9 cswrap [--help | --print-path-to-wrap]
10
12 cswrap is a generic compiler wrapper that translates relative paths to
13 absolute paths in diagnostic messages. Create a symbolic link to cswrap
14 named as your compiler (gcc, g++, ...) and put it to your $PATH.
15 Translated diagnostic messages are decorated by suffix <--[TOOL] if
17 they are produced by a tool named TOOL (given by cswrap invokation via
18 symlink named TOOL). This only applies to translated diagnostic
19 messages, which does not include code snippets, for instance.
20 If cswrap is installed on system, the following command activates the
22 wrapper:
23 export PATH="$(cswrap --print-path-to-wrap):$PATH"
25
27 --help
28 Prints basic usage information.
29 --print-path-to-wrap
31 Prints path to the directory with symlinks to the cswrap
32 executable.
33
35 cswrap propagates the exit status returned by the compiler (in case
36 cswrap succeeds to run the compiler).
37
39 CSWRAP_CAP_FILE
40 If set to a non-empty string, cswrap captures diagnostic messages
41 into a file named $CSWRAP_CAP_FILE. In this case, the capture file
42 is protected by a lock named /cswrap_cap_file_lock in order to
43 obtain consistent output when running multiple compiler processes
44 in parallel.
45 CSWRAP_TIMEOUT
47 If set to a positive integer, cswrap installs a timeout for the
48 compiler being wrapped. If the specified amount of time (given in
49 seconds) elapses the compiler process is signalled by SIGTERM. Note
50 the cswrap process waits till the compiler process finishes in any
51 case.
52 CSWRAP_TIMEOUT_FOR
54 Colon-separated list of programs (compilers) that $CSWRAP_TIMEOUT
55 should be applied to. If $CSWRAP_TIMEOUT_FOR is unset or empty,
56 $CSWRAP_TIMEOUT applies to all programs.
57 CSWRAP_DEL_CFLAGS, CSWRAP_DEL_CXXFLAGS
59 cswrap expects a colon-separated list of compiler flags that should
60 be removed from command line prior to invoking the compiler. The
61 parameters are matched for exact match and they are case-sensitive.
62 If a compiler flag appears in the command line multiple times, all
63 its occurrences are removed. $CSWRAP_DEL_CFLAGS applies to
64 compilation of C sources only. $CSWRAP_DEL_CXXFLAGS applies to
65 compilation of C++ sources only. Flags to be removed can be
66 specified by shell wildcard patterns (using the format accepted by
67 fnmatch(3)).
68 CSWRAP_ADD_CFLAGS, CSWRAP_ADD_CXXFLAGS
70 cswrap expects a colon-separated list of compiler flags that should
71 be appended to command line prior to invoking the compiler. The
72 flags are appended even if they already appear in the command line
73 and they are always appended at the end of the command line.
74 $CSWRAP_ADD_CFLAGS applies to compilation of C sources only.
75 $CSWRAP_ADD_CXXFLAGS applies to compilation of C++ sources only.
