6 perlcygwin - Perl for Cygwin
7
9 This document will help you configure, make, test and install Perl on
10 Cygwin. This document also describes features of Cygwin that will
11 affect how Perl behaves at runtime.
12
13 NOTE: There are pre-built Perl packages available for Cygwin and a
14 version of Perl is provided in the normal Cygwin install. If you do
15 not need to customize the configuration, consider using one of those
16 packages.
17
19 Cygwin = GNU+Cygnus+Windows (Don't leave UNIX without it)
20 The Cygwin tools are ports of the popular GNU development tools for
21 Win32 platforms. They run thanks to the Cygwin library which provides
22 the UNIX system calls and environment these programs expect. More
23 information about this project can be found at:
24
25 <http://www.cygwin.com/>
26
27 A recent net or commercial release of Cygwin is required.
28
29 At the time this document was last updated, Cygwin 1.7.10 was current.
30
31 Cygwin Configuration
32 While building Perl some changes may be necessary to your Cygwin setup
33 so that Perl builds cleanly. These changes are not required for normal
34 Perl usage.
35
36 NOTE: The binaries that are built will run on all Win32 versions. They
37 do not depend on your host system (WinXP/Win2K/Win7) or your Cygwin
38 configuration (binary/text mounts, cvgserver). The only dependencies
39 come from hard-coded pathnames like "/usr/local". However, your host
40 system and Cygwin configuration will affect Perl's runtime behavior
41 (see "TEST").
42
43 · "PATH"
44
45 Set the "PATH" environment variable so that Configure finds the
46 Cygwin versions of programs. Any not-needed Windows directories
47 should be removed or moved to the end of your "PATH".
48
49 · nroff
50
51 If you do not have nroff (which is part of the groff package),
52 Configure will not prompt you to install man pages.
53
55 The default options gathered by Configure with the assistance of
56 hints/cygwin.sh will build a Perl that supports dynamic loading (which
57 requires a shared cygperl5_16.dll).
58
59 This will run Configure and keep a record:
60
61 ./Configure 2>&1 | tee log.configure
62
63 If you are willing to accept all the defaults run Configure with -de.
64 However, several useful customizations are available.
65
66 Stripping Perl Binaries on Cygwin
67 It is possible to strip the EXEs and DLLs created by the build process.
68 The resulting binaries will be significantly smaller. If you want the
69 binaries to be stripped, you can either add a -s option when Configure
70 prompts you,
71
72 Any additional ld flags (NOT including libraries)? [none] -s
73 Any special flags to pass to g++ to create a dynamically loaded library?
74 [none] -s
75 Any special flags to pass to gcc to use dynamic linking? [none] -s
76
77 or you can edit hints/cygwin.sh and uncomment the relevant variables
78 near the end of the file.
79
80 Optional Libraries for Perl on Cygwin
81 Several Perl functions and modules depend on the existence of some
82 optional libraries. Configure will find them if they are installed in
83 one of the directories listed as being used for library searches. Pre-
84 built packages for most of these are available from the Cygwin
85 installer.
86
87 · "-lcrypt"
88
89 The crypt package distributed with Cygwin is a Linux compatible
90 56-bit DES crypt port by Corinna Vinschen.
91
92 Alternatively, the crypt libraries in GNU libc have been ported to
93 Cygwin.
94
95 · "-lgdbm_compat" ("use GDBM_File")
96
97 GDBM is available for Cygwin.
98
99 NOTE: The GDBM library only works on NTFS partitions.
100
101 · "-ldb" ("use DB_File")
102
103 BerkeleyDB is available for Cygwin.
104
105 NOTE: The BerkeleyDB library only completely works on NTFS
106 partitions.
107
108 · "cygserver" ("use IPC::SysV")
109
110 A port of SysV IPC is available for Cygwin.
111
112 NOTE: This has not been extensively tested. In particular,
113 "d_semctl_semun" is undefined because it fails a Configure test and
114 on Win9x the shm*() functions seem to hang. It also creates a
115 compile time dependency because perl.h includes <sys/ipc.h> and
116 <sys/sem.h> (which will be required in the future when compiling
117 CPAN modules). CURRENTLY NOT SUPPORTED!
118
119 · "-lutil"
120
121 Included with the standard Cygwin netrelease is the inetutils
122 package which includes libutil.a.
123
124 Configure-time Options for Perl on Cygwin
125 The INSTALL document describes several Configure-time options. Some of
126 these will work with Cygwin, others are not yet possible. Also, some
127 of these are experimental. You can either select an option when
128 Configure prompts you or you can define (undefine) symbols on the
129 command line.
130
131 · "-Uusedl"
132
133 Undefining this symbol forces Perl to be compiled statically.
134
135 · "-Dusemymalloc"
136
137 By default Perl does not use the "malloc()" included with the Perl
138 source, because it was slower and not entirely thread-safe. If you
139 want to force Perl to build with the old -Dusemymalloc define this.
140
141 · "-Uuseperlio"
142
143 Undefining this symbol disables the PerlIO abstraction. PerlIO is
144 now the default; it is not recommended to disable PerlIO.
145
146 · "-Dusemultiplicity"
147
148 Multiplicity is required when embedding Perl in a C program and
149 using more than one interpreter instance. This is only required
150 when you build a not-threaded perl with "-Uuseithreads".
151
152 · "-Uuse64bitint"
153
154 By default Perl uses 64 bit integers. If you want to use smaller
155 32 bit integers, define this symbol.
156
157 · "-Duselongdouble"
158
159 gcc supports long doubles (12 bytes). However, several additional
160 long double math functions are necessary to use them within Perl
161 ({atan2, cos, exp, floor, fmod, frexp, isnan, log, modf, pow, sin,
162 sqrt}l, strtold). These are not yet available with newlib, the
163 Cygwin libc.
164
165 · "-Uuseithreads"
166
167 Define this symbol if you want not-threaded faster perl.
168
169 · "-Duselargefiles"
170
171 Cygwin uses 64-bit integers for internal size and position
172 calculations, this will be correctly detected and defined by
173 Configure.
174
175 · "-Dmksymlinks"
176
177 Use this to build perl outside of the source tree. Details can be
178 found in the INSTALL document. This is the recommended way to
179 build perl from sources.
180
181 Suspicious Warnings on Cygwin
182 You may see some messages during Configure that seem suspicious.
183
184 · Win9x and "d_eofnblk"
185
186 Win9x does not correctly report "EOF" with a non-blocking read on a
187 closed pipe. You will see the following messages:
188
189 But it also returns -1 to signal EOF, so be careful!
190 WARNING: you can't distinguish between EOF and no data!
191
192 *** WHOA THERE!!! ***
193 The recommended value for $d_eofnblk on this machine was "define"!
194 Keep the recommended value? [y]
195
196 At least for consistency with WinNT, you should keep the
197 recommended value.
198
199 · Compiler/Preprocessor defines
200
201 The following error occurs because of the Cygwin "#define" of
202 "_LONG_DOUBLE":
203
204 Guessing which symbols your C compiler and preprocessor define...
205 try.c:<line#>: missing binary operator
206
207 This failure does not seem to cause any problems. With older gcc
208 versions, "parse error" is reported instead of "missing binary
209 operator".
210
212 Simply run make and wait:
213
214 make 2>&1 | tee log.make
215
217 There are two steps to running the test suite:
218
219 make test 2>&1 | tee log.make-test
220
221 cd t; ./perl harness 2>&1 | tee ../log.harness
222
223 The same tests are run both times, but more information is provided
224 when running as "./perl harness".
225
226 Test results vary depending on your host system and your Cygwin
227 configuration. If a test can pass in some Cygwin setup, it is always
228 attempted and explainable test failures are documented. It is possible
229 for Perl to pass all the tests, but it is more likely that some tests
230 will fail for one of the reasons listed below.
231
232 File Permissions on Cygwin
233 UNIX file permissions are based on sets of mode bits for
234 {read,write,execute} for each {user,group,other}. By default Cygwin
235 only tracks the Win32 read-only attribute represented as the UNIX file
236 user write bit (files are always readable, files are executable if they
237 have a .{com,bat,exe} extension or begin with "#!", directories are
238 always readable and executable). On WinNT with the ntea "CYGWIN"
239 setting, the additional mode bits are stored as extended file
240 attributes. On WinNT with the default ntsec "CYGWIN" setting,
241 permissions use the standard WinNT security descriptors and access
242 control lists. Without one of these options, these tests will fail
243 (listing not updated yet):
244
245 Failed Test List of failed
246 ------------------------------------
247 io/fs.t 5, 7, 9-10
248 lib/anydbm.t 2
249 lib/db-btree.t 20
250 lib/db-hash.t 16
251 lib/db-recno.t 18

253 lib/ndbm.t 2
254 lib/odbm.t 2
255 lib/sdbm.t 2
256 op/stat.t 9, 20 (.tmp not an executable extension)
257
258 NDBM_File and ODBM_File do not work on FAT filesystems
259 Do not use NDBM_File or ODBM_File on FAT filesystem. They can be built
260 on a FAT filesystem, but many tests will fail:
261
262 ../ext/NDBM_File/ndbm.t 13 3328 71 59 83.10% 1-2 4 16-71
263 ../ext/ODBM_File/odbm.t 255 65280 ?? ?? % ??
264 ../lib/AnyDBM_File.t 2 512 12 2 16.67% 1 4
265 ../lib/Memoize/t/errors.t 0 139 11 5 45.45% 7-11
266 ../lib/Memoize/t/tie_ndbm.t 13 3328 4 4 100.00% 1-4
267 run/fresh_perl.t 97 1 1.03% 91
268
269 If you intend to run only on FAT (or if using AnyDBM_File on FAT), run
270 Configure with the -Ui_ndbm and -Ui_dbm options to prevent NDBM_File
271 and ODBM_File being built.
272
273 With NTFS (and no CYGWIN=nontsec), there should be no problems even if
274 perl was built on FAT.
275
276 "fork()" failures in io_* tests
277 A "fork()" failure may result in the following tests failing:
278
279 ext/IO/lib/IO/t/io_multihomed.t
280 ext/IO/lib/IO/t/io_sock.t
281 ext/IO/lib/IO/t/io_unix.t
282
283 See comment on fork in "Miscellaneous" below.
284
286 Script Portability on Cygwin
287 Cygwin does an outstanding job of providing UNIX-like semantics on top
288 of Win32 systems. However, in addition to the items noted above, there
289 are some differences that you should know about. This is a very brief
290 guide to portability, more information can be found in the Cygwin
291 documentation.
292
293 · Pathnames
294
295 Cygwin pathnames are separated by forward (/) slashes, Universal
296 Naming Codes (//UNC) are also supported Since cygwin-1.7 non-POSIX
297 pathnames are disencouraged. Names may contain all printable
298 characters.
299
300 File names are case insensitive, but case preserving. A pathname
301 that contains a backslash or drive letter is a Win32 pathname, and
302 not subject to the translations applied to POSIX style pathnames,
303 but cygwin will warn you, so better convert them to POSIX.
304
305 For conversion we have "Cygwin::win_to_posix_path()" and
306 "Cygwin::posix_to_win_path()".
307
308 Since cygwin-1.7 pathnames are UTF-8 encoded.
309
310 · Text/Binary
311
312 Since cywgin-1.7 textmounts are deprecated and stronlgy
313 discouraged.
314
315 When a file is opened it is in either text or binary mode. In text
316 mode a file is subject to CR/LF/Ctrl-Z translations. With Cygwin,
317 the default mode for an "open()" is determined by the mode of the
318 mount that underlies the file. See "Cygwin::is_binmount"(). Perl
319 provides a "binmode()" function to set binary mode on files that
320 otherwise would be treated as text. "sysopen()" with the "O_TEXT"
321 flag sets text mode on files that otherwise would be treated as
322 binary:
323
324 sysopen(FOO, "bar", O_WRONLY|O_CREAT|O_TEXT)
325
326 "lseek()", "tell()" and "sysseek()" only work with files opened in
327 binary mode.
328
329 The text/binary issue is covered at length in the Cygwin
330 documentation.
331
332 · PerlIO
333
334 PerlIO overrides the default Cygwin Text/Binary behaviour. A file
335 will always be treated as binary, regardless of the mode of the
336 mount it lives on, just like it is in UNIX. So CR/LF translation
337 needs to be requested in either the "open()" call like this:
338
339 open(FH, ">:crlf", "out.txt");
340
341 which will do conversion from LF to CR/LF on the output, or in the
342 environment settings (add this to your .bashrc):
343
344 export PERLIO=crlf
345
346 which will pull in the crlf PerlIO layer which does LF -> CRLF
347 conversion on every output generated by perl.
348
349 · .exe
350
351 The Cygwin "stat()", "lstat()" and "readlink()" functions make the
352 .exe extension transparent by looking for foo.exe when you ask for
353 foo (unless a foo also exists). Cygwin does not require a .exe
354 extension, but gcc adds it automatically when building a program.
355 However, when accessing an executable as a normal file (e.g., cp in
356 a makefile) the .exe is not transparent. The install program
357 included with Cygwin automatically appends a .exe when necessary.
358
359 · Cygwin vs. Windows process ids
360
361 Cygwin processes have their own pid, which is different from the
362 underlying windows pid. Most posix compliant Proc functions expect
363 the cygwin pid, but several Win32::Process functions expect the
364 winpid. E.g. $$ is the cygwin pid of /usr/bin/perl, which is not
365 the winpid. Use "Cygwin::winpid_to_pid()" and
366 "Cygwin::winpid_to_pid()" to translate between them.
367
368 · Cygwin vs. Windows errors
369
370 Under Cygwin, $^E is the same as $!. When using Win32 API
371 Functions, use "Win32::GetLastError()" to get the last Windows
372 error.
373
374 · rebase errors on fork or system
375
376 Using "fork()" or "system()" out to another perl after loading
377 multiple dlls may result on a DLL baseaddress conflict. The
378 internal cygwin error looks like like the following:
379
380 0 [main] perl 8916 child_info_fork::abort: data segment start: parent
381 (0xC1A000) != child(0xA6A000)
382
383 or:
384
385 183 [main] perl 3588 C:\cygwin\bin\perl.exe: *** fatal error - unable to remap C:\cygwin\bin\cygsvn_subr-1-0.dll to same address as parent(0x6FB30000) != 0x6FE60000
386 46 [main] perl 3488 fork: child 3588 - died waiting for dll loading, errno11
387
388 See
389 http://cygwin.com/faq/faq-nochunks.html#faq.using.fixing-fork-failures
390 <http://cygwin.com/faq/faq-nochunks.html#faq.using.fixing-fork-
391 failures> It helps if not too many DLLs are loaded in memory so the
392 available address space is larger, e.g. stopping the MS Internet
393 Explorer might help.
394
395 Use the perlrebase or rebase utilities to resolve the conflicting
396 dll addresses. The rebase package is included in the Cygwin setup.
397 Use setup.exe from <http://www.cygwin.com/setup.exe> to install it.
398
399 1. kill all perl processes and run "perlrebase" or
400
401 2. kill all cygwin processes and services, start dash from cmd.exe
402 and run "rebaseall".
403
404 · "chown()"
405
406 On WinNT "chown()" can change a file's user and group IDs. On
407 Win9x "chown()" is a no-op, although this is appropriate since
408 there is no security model.
409
410 · Miscellaneous
411
412 File locking using the "F_GETLK" command to "fcntl()" is a stub
413 that returns "ENOSYS".
414
415 Win9x can not "rename()" an open file (although WinNT can).
416
417 The Cygwin "chroot()" implementation has holes (it can not restrict
418 file access by native Win32 programs).
419
420 Inplace editing "perl -i" of files doesn't work without doing a
421 backup of the file being edited "perl -i.bak" because of windowish
422 restrictions, therefore Perl adds the suffix ".bak" automatically
423 if you use "perl -i" without specifying a backup extension.
424
425 Prebuilt methods:
426 "Cwd::cwd"
427 Returns the current working directory.
428
429 "Cygwin::pid_to_winpid"
430 Translates a cygwin pid to the corresponding Windows pid (which may
431 or may not be the same).
432
433 "Cygwin::winpid_to_pid"
434 Translates a Windows pid to the corresponding cygwin pid (if any).
435
436 "Cygwin::win_to_posix_path"
437 Translates a Windows path to the corresponding cygwin path
438 respecting the current mount points. With a second non-null
439 argument returns an absolute path. Double-byte characters will not
440 be translated.
441
442 "Cygwin::posix_to_win_path"
443 Translates a cygwin path to the corresponding cygwin path
444 respecting the current mount points. With a second non-null
445 argument returns an absolute path. Double-byte characters will not
446 be translated.
447
448 "Cygwin::mount_table()"
449 Returns an array of [mnt_dir, mnt_fsname, mnt_type, mnt_opts].
450
451 perl -e 'for $i (Cygwin::mount_table) {print join(" ",@$i),"\n";}'
452 /bin c:\cygwin\bin system binmode,cygexec
453 /usr/bin c:\cygwin\bin system binmode
454 /usr/lib c:\cygwin\lib system binmode
455 / c:\cygwin system binmode
456 /cygdrive/c c: system binmode,noumount
457 /cygdrive/d d: system binmode,noumount
458 /cygdrive/e e: system binmode,noumount
459
460 "Cygwin::mount_flags"
461 Returns the mount type and flags for a specified mount point. A
462 comma-separated string of mntent->mnt_type (always "system" or
463 "user"), then the mntent->mnt_opts, where the first is always
464 "binmode" or "textmode".
465
466 system|user,binmode|textmode,exec,cygexec,cygdrive,mixed,
467 notexec,managed,nosuid,devfs,proc,noumount
468
469 If the argument is "/cygdrive", then just the volume mount
470 settings, and the cygdrive mount prefix are returned.
471
472 User mounts override system mounts.
473
474 $ perl -e 'print Cygwin::mount_flags "/usr/bin"'
475 system,binmode,cygexec
476 $ perl -e 'print Cygwin::mount_flags "/cygdrive"'
477 binmode,cygdrive,/cygdrive
478
479 "Cygwin::is_binmount"
480 Returns true if the given cygwin path is binary mounted, false if
481 the path is mounted in textmode.
482
483 "Cygwin::sync_winenv"
484 Cygwin does not initialize all original Win32 environment
485 variables. See the bottom of this page
486 http://cygwin.com/cygwin-ug-net/setup-env.html
487 <http://cygwin.com/cygwin-ug-net/setup-env.html> for "Restricted
488 Win32 environment".
489
490 Certain Win32 programs called from cygwin programs might need some
491 environment variable, such as e.g. ADODB needs
492 %COMMONPROGRAMFILES%. Call Cygwin::sync_winenv() to copy all Win32
493 environment variables to your process and note that cygwin will
494 warn on every encounter of non-POSIX paths.
495
497 This will install Perl, including man pages.
498
499 make install 2>&1 | tee log.make-install
500
501 NOTE: If "STDERR" is redirected "make install" will not prompt you to
502 install perl into /usr/bin.
503
504 You may need to be Administrator to run "make install". If you are
505 not, you must have write access to the directories in question.
506
507 Information on installing the Perl documentation in HTML format can be
508 found in the INSTALL document.
509
511 These are the files in the Perl release that contain references to
512 Cygwin. These very brief notes attempt to explain the reason for all
513 conditional code. Hopefully, keeping this up to date will allow the
514 Cygwin port to be kept as clean as possible.

712 Support for swapping real and effective user and group IDs is
713 incomplete. On WinNT Cygwin provides "setuid()", "seteuid()",
714 "setgid()" and "setegid()". However, additional Cygwin calls for
715 manipulating WinNT access tokens and security contexts are required.
