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 <https://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 3.0.7 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 or your Cygwin configuration
38 (binary/text mounts, cygserver). The only dependencies come from hard-
39 coded pathnames like /usr/local. However, your host system and Cygwin
40 configuration will affect Perl's runtime behavior (see "TEST").
41
42 • "PATH"
43
44 Set the "PATH" environment variable so that Configure finds the
45 Cygwin versions of programs. Any not-needed Windows directories
46 should be removed or moved to the end of your "PATH".
47
48 • nroff
49
50 If you do not have nroff (which is part of the groff package),
51 Configure will not prompt you to install man pages.
52
54 The default options gathered by Configure with the assistance of
55 hints/cygwin.sh will build a Perl that supports dynamic loading (which
56 requires a shared cygperl5_16.dll).
57
58 This will run Configure and keep a record:
59
60 ./Configure 2>&1 | tee log.configure
61
62 If you are willing to accept all the defaults run Configure with -de.
63 However, several useful customizations are available.
64
65 Stripping Perl Binaries on Cygwin
66 It is possible to strip the EXEs and DLLs created by the build process.
67 The resulting binaries will be significantly smaller. If you want the
68 binaries to be stripped, you can either add a -s option when Configure
69 prompts you,
70
71 Any additional ld flags (NOT including libraries)? [none] -s
72 Any special flags to pass to g++ to create a dynamically loaded
73 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 As of libcrypt 1.3 (March 2016), you will need to install the
96 libcrypt-devel package for Configure to detect crypt().
97
98 • "-lgdbm_compat" ("use GDBM_File")
99
100 GDBM is available for Cygwin.
101
102 NOTE: The GDBM library only works on NTFS partitions.
103
104 • "-ldb" ("use DB_File")
105
106 BerkeleyDB is available for Cygwin.
107
108 NOTE: The BerkeleyDB library only completely works on NTFS
109 partitions.
110
111 • "cygserver" ("use IPC::SysV")
112
113 A port of SysV IPC is available for Cygwin.
114
115 NOTE: This has not been extensively tested. In particular,
116 "d_semctl_semun" is undefined because it fails a Configure test.
117 It also creates a compile time dependency because perl.h includes
118 <sys/ipc.h> and <sys/sem.h> (which will be required in the future
119 when compiling CPAN modules). CURRENTLY NOT SUPPORTED!
120
121 • "-lutil"
122
123 Included with the standard Cygwin netrelease is the inetutils
124 package which includes libutil.a.
125
126 Configure-time Options for Perl on Cygwin
127 The INSTALL document describes several Configure-time options. Some of
128 these will work with Cygwin, others are not yet possible. Also, some
129 of these are experimental. You can either select an option when
130 Configure prompts you or you can define (undefine) symbols on the
131 command line.
132
133 • "-Uusedl"
134
135 Undefining this symbol forces Perl to be compiled statically.
136
137 • "-Dusemymalloc"
138
139 By default Perl does not use the malloc() included with the Perl
140 source, because it was slower and not entirely thread-safe. If you
141 want to force Perl to build with the old -Dusemymalloc define this.
142
143 • "-Uuseperlio"
144
145 Undefining this symbol disables the PerlIO abstraction. PerlIO is
146 now the default; it is not recommended to disable PerlIO.
147
148 • "-Dusemultiplicity"
149
150 Multiplicity is required when embedding Perl in a C program and
151 using more than one interpreter instance. This is only required
152 when you build a not-threaded perl with "-Uuseithreads".
153
154 • "-Uuse64bitint"
155
156 By default Perl uses 64 bit integers. If you want to use smaller
157 32 bit integers, define this symbol.
158
159 • "-Duselongdouble"
160
161 gcc supports long doubles (12 bytes). However, several additional
162 long double math functions are necessary to use them within Perl
163 ({atan2, cos, exp, floor, fmod, frexp, isnan, log, modf, pow, sin,
164 sqrt}l, strtold). These are not yet available with newlib, the
165 Cygwin libc.
166
167 • "-Uuseithreads"
168
169 Define this symbol if you want not-threaded faster perl.
170
171 • "-Duselargefiles"
172
173 Cygwin uses 64-bit integers for internal size and position
174 calculations, this will be correctly detected and defined by
175 Configure.
176
177 • "-Dmksymlinks"
178
179 Use this to build perl outside of the source tree. Details can be
180 found in the INSTALL document. This is the recommended way to
181 build perl from sources.
182
184 Simply run make and wait:
185
186 make -jn 2>&1 | tee log.make
187
188 where n is the maximum number of simultaneous compilations you want;
189 omitting this parameter is the same as specifying "-j1".
190
192 There are two steps to running the test suite:
193
194 make test 2>&1 | tee log.make-test
195
196 cd t; ./perl harness 2>&1 | tee ../log.harness
197
198 The same tests are run both times, but more information is provided
199 when running as "./perl harness", and you can run the tests in parallel
200 by instead specifying
201
202 cd t; TEST_JOBS=n ./perl harness 2>&1 | tee ../log.harness
203
204 where n is the maximum number of tests to run simulataneously.
205
206 Test results vary depending on your host system and your Cygwin
207 configuration. If a test can pass in some Cygwin setup, it is always
208 attempted and explainable test failures are documented. It is possible
209 for Perl to pass all the tests, but it is more likely that some tests
210 will fail for one of the reasons listed below.
211
212 File Permissions on Cygwin
213 UNIX file permissions are based on sets of mode bits for
214 {read,write,execute} for each {user,group,other}. By default Cygwin
215 only tracks the Win32 read-only attribute represented as the UNIX file
216 user write bit (files are always readable, files are executable if they
217 have a .{com,bat,exe} extension or begin with "#!", directories are
218 always readable and executable). On WinNT with the ntea "CYGWIN"
219 setting, the additional mode bits are stored as extended file
220 attributes. On WinNT with the default ntsec "CYGWIN" setting,
221 permissions use the standard WinNT security descriptors and access
222 control lists. Without one of these options, these tests will fail
223 (listing not updated yet):
224
225 Failed Test List of failed
226 ------------------------------------
227 io/fs.t 5, 7, 9-10
228 lib/anydbm.t 2
229 lib/db-btree.t 20
230 lib/db-hash.t 16
231 lib/db-recno.t 18
232 lib/gdbm.t 2
233 lib/ndbm.t 2
234 lib/odbm.t 2
235 lib/sdbm.t 2
236 op/stat.t 9, 20 (.tmp not an executable extension)
237
238 NDBM_File and ODBM_File do not work on FAT filesystems
239 Do not use NDBM_File or ODBM_File on FAT filesystem. They can be built
240 on a FAT filesystem, but many tests will fail:
241
242 ../ext/NDBM_File/ndbm.t 13 3328 71 59 83.10% 1-2 4 16-71
243 ../ext/ODBM_File/odbm.t 255 65280 ?? ?? % ??
244 ../lib/AnyDBM_File.t 2 512 12 2 16.67% 1 4
245 ../lib/Memoize/t/errors.t 0 139 11 5 45.45% 7-11
246 ../lib/Memoize/t/tie_ndbm.t 13 3328 4 4 100.00% 1-4
247 run/fresh_perl.t 97 1 1.03% 91
248
249 If you intend to run only on FAT (or if using AnyDBM_File on FAT), run
250 Configure with the -Ui_ndbm and -Ui_dbm options to prevent NDBM_File
251 and ODBM_File being built.
252
253 With NTFS (and no CYGWIN=nontsec), there should be no problems even if
254 perl was built on FAT.
255
256 fork() failures in io_* tests
257 A fork() failure may result in the following tests failing:
258
259 ext/IO/lib/IO/t/io_multihomed.t
260 ext/IO/lib/IO/t/io_sock.t
261 ext/IO/lib/IO/t/io_unix.t
262
263 See comment on fork in "Miscellaneous" below.
264
266 Script Portability on Cygwin
267 Cygwin does an outstanding job of providing UNIX-like semantics on top
268 of Win32 systems. However, in addition to the items noted above, there
269 are some differences that you should know about. This is a very brief
270 guide to portability, more information can be found in the Cygwin
271 documentation.
272
273 • Pathnames
274
275 Cygwin pathnames are separated by forward (/) slashes, Universal
276 Naming Codes (//UNC) are also supported. Since cygwin-1.7 non-
277 POSIX pathnames should not be used. Names may contain all
278 printable characters.
279
280 File names are case insensitive, but case preserving. A pathname
281 that contains a backslash or drive letter is a Win32 pathname, and
282 not subject to the translations applied to POSIX style pathnames,
283 but cygwin will warn you, so better convert them to POSIX.
284
285 For conversion we have Cygwin::win_to_posix_path() and
286 Cygwin::posix_to_win_path().
287
288 Since cygwin-1.7 pathnames are UTF-8 encoded.
289
290 • Text/Binary
291
292 Since cygwin-1.7 textmounts are deprecated and strongly
293 discouraged.
294
295 When a file is opened it is in either text or binary mode. In text
296 mode a file is subject to CR/LF/Ctrl-Z translations. With Cygwin,
297 the default mode for an open() is determined by the mode of the
298 mount that underlies the file. See "Cygwin::is_binmount"(). Perl
299 provides a binmode() function to set binary mode on files that
300 otherwise would be treated as text. sysopen() with the "O_TEXT"
301 flag sets text mode on files that otherwise would be treated as
302 binary:
303
304 sysopen(FOO, "bar", O_WRONLY|O_CREAT|O_TEXT)
305
306 lseek(), tell() and sysseek() only work with files opened in binary
307 mode.
308
309 The text/binary issue is covered at length in the Cygwin
310 documentation.
311
312 • PerlIO
313
314 PerlIO overrides the default Cygwin Text/Binary behaviour. A file
315 will always be treated as binary, regardless of the mode of the
316 mount it lives on, just like it is in UNIX. So CR/LF translation
317 needs to be requested in either the open() call like this:
318
319 open(FH, ">:crlf", "out.txt");
320
321 which will do conversion from LF to CR/LF on the output, or in the
322 environment settings (add this to your .bashrc):
323
324 export PERLIO=crlf
325
326 which will pull in the crlf PerlIO layer which does LF -> CRLF
327 conversion on every output generated by perl.
328
329 • .exe
330
331 The Cygwin stat(), lstat() and readlink() functions make the .exe
332 extension transparent by looking for foo.exe when you ask for foo
333 (unless a foo also exists). Cygwin does not require a .exe
334 extension, but gcc adds it automatically when building a program.
335 However, when accessing an executable as a normal file (e.g., cp in
336 a makefile) the .exe is not transparent. The install program
337 included with Cygwin automatically appends a .exe when necessary.
338
339 • Cygwin vs. Windows process ids
340
341 Cygwin processes have their own pid, which is different from the
342 underlying windows pid. Most posix compliant Proc functions expect
343 the cygwin pid, but several Win32::Process functions expect the
344 winpid. E.g. $$ is the cygwin pid of /usr/bin/perl, which is not
345 the winpid. Use Cygwin::pid_to_winpid() and
346 Cygwin::winpid_to_pid() to translate between them.
347
348 • Cygwin vs. Windows errors
349
350 Under Cygwin, $^E is the same as $!. When using Win32 API
351 Functions, use Win32::GetLastError() to get the last Windows error.
352
353 • rebase errors on fork or system
354
355 Using fork() or system() out to another perl after loading multiple
356 dlls may result on a DLL baseaddress conflict. The internal cygwin
357 error looks like like the following:
358
359 0 [main] perl 8916 child_info_fork::abort: data segment start:
360 parent (0xC1A000) != child(0xA6A000)
361
362 or:
363
364 183 [main] perl 3588 C:\cygwin\bin\perl.exe: *** fatal error -
365 unable to remap C:\cygwin\bin\cygsvn_subr-1-0.dll to same address
366 as parent(0x6FB30000) != 0x6FE60000 46 [main] perl 3488 fork: child
367 3588 - died waiting for dll loading, errno11
368
369 See
370 <https://cygwin.com/faq/faq.html#faq.using.fixing-fork-failures> It
371 helps if not too many DLLs are loaded in memory so the available
372 address space is larger, e.g. stopping the MS Internet Explorer
373 might help.
374
375 +Use the rebase utilities to resolve the conflicting dll addresses.
376 The rebase package is included in the Cygwin setup. Use setup.exe
377 from <https://cygwin.com/install.html> to install it.
378
379 1. kill all perl processes and run
380 "</bin/find <dir" -xdev -name \*.dll | /bin/rebase -OT ->> or
381
382 2. kill all cygwin processes and services, and run setup.exe.
383
384 • Miscellaneous
385
386 File locking using the "F_GETLK" command to fcntl() is a stub that
387 returns "ENOSYS".
388
389 The Cygwin chroot() implementation has holes (it can not restrict
390 file access by native Win32 programs).
391
392 Inplace editing "perl -i" of files doesn't work without doing a
393 backup of the file being edited "perl -i.bak" because of windowish
394 restrictions, therefore Perl adds the suffix ".bak" automatically
395 if you use "perl -i" without specifying a backup extension.
396
397 Prebuilt methods:
398 "Cwd::cwd"
399 Returns the current working directory.
400
401 "Cygwin::pid_to_winpid"
402 Translates a cygwin pid to the corresponding Windows pid (which may
403 or may not be the same).
404
405 "Cygwin::winpid_to_pid"
406 Translates a Windows pid to the corresponding cygwin pid (if any).
407
408 "Cygwin::win_to_posix_path"
409 Translates a Windows path to the corresponding cygwin path
410 respecting the current mount points. With a second non-null
411 argument returns an absolute path. Double-byte characters will not
412 be translated.
413
414 "Cygwin::posix_to_win_path"
415 Translates a cygwin path to the corresponding cygwin path
416 respecting the current mount points. With a second non-null
417 argument returns an absolute path. Double-byte characters will not
418 be translated.
419
420 Cygwin::mount_table()
421 Returns an array of [mnt_dir, mnt_fsname, mnt_type, mnt_opts].
422
423 perl -e 'for $i (Cygwin::mount_table) {print join(" ",@$i),"\n";}'
424 /bin c:\cygwin\bin system binmode,cygexec
425 /usr/bin c:\cygwin\bin system binmode
426 /usr/lib c:\cygwin\lib system binmode
427 / c:\cygwin system binmode
428 /cygdrive/c c: system binmode,noumount
429 /cygdrive/d d: system binmode,noumount
430 /cygdrive/e e: system binmode,noumount
431
432 "Cygwin::mount_flags"
433 Returns the mount type and flags for a specified mount point. A
434 comma-separated string of mntent->mnt_type (always "system" or
435 "user"), then the mntent->mnt_opts, where the first is always
436 "binmode" or "textmode".
437
438 system|user,binmode|textmode,exec,cygexec,cygdrive,mixed,
439 notexec,managed,nosuid,devfs,proc,noumount
440
441 If the argument is "/cygdrive", then just the volume mount
442 settings, and the cygdrive mount prefix are returned.
443
444 User mounts override system mounts.
445
446 $ perl -e 'print Cygwin::mount_flags "/usr/bin"'
447 system,binmode,cygexec
448 $ perl -e 'print Cygwin::mount_flags "/cygdrive"'
449 binmode,cygdrive,/cygdrive
450
451 "Cygwin::is_binmount"
452 Returns true if the given cygwin path is binary mounted, false if
453 the path is mounted in textmode.
454
455 "Cygwin::sync_winenv"
456 Cygwin does not initialize all original Win32 environment
457 variables. See the bottom of this page
458 <https://cygwin.com/cygwin-ug-net/setup-env.html> for "Restricted
459 Win32 environment".
460
461 Certain Win32 programs called from cygwin programs might need some
462 environment variable, such as e.g. ADODB needs
463 %COMMONPROGRAMFILES%. Call Cygwin::sync_winenv() to copy all Win32
464 environment variables to your process and note that cygwin will
465 warn on every encounter of non-POSIX paths.
466
468 This will install Perl, including man pages.
469
470 make install 2>&1 | tee log.make-install
471
472 NOTE: If "STDERR" is redirected "make install" will not prompt you to
473 install perl into /usr/bin.
474
475 You may need to be Administrator to run "make install". If you are
476 not, you must have write access to the directories in question.
477
478 Information on installing the Perl documentation in HTML format can be
479 found in the INSTALL document.
480
482 These are the files in the Perl release that contain references to
483 Cygwin. These very brief notes attempt to explain the reason for all
484 conditional code. Hopefully, keeping this up to date will allow the
485 Cygwin port to be kept as clean as possible.
