14 # This script acts as a simple interface for building extensions. | |
15 | |
16 # It's actually a cut and shut of the Unix version ext/utils/makeext and the | |
17 # Windows version win32/build_ext.pl hence the two invocation styles. | |
18 | |
19 # On Unix, it primarily used by the perl Makefile one extension at a time: | |
20 # | |
21 # d_dummy $(dynamic_ext): miniperl preplibrary FORCE | |
22 # @$(RUN) ./miniperl make_ext.pl --target=dynamic $@ MAKE=$(MAKE) LIBPERL_A=$(LIBPERL) | |
23 # | |
24 # On Windows or VMS, | |
25 # If '--static' is specified, static extensions will be built. | |
26 # If '--dynamic' is specified, dynamic extensions will be built. | |
27 # If '--nonxs' is specified, nonxs extensions will be built. | |
28 # If '--dynaloader' is specified, DynaLoader will be built. | |
29 # If '--all' is specified, all extensions will be built. | |
30 # | |
31 # make_ext.pl "MAKE=make [-make_opts]" --dir=directory [--target=target] [--static|--dynamic|--all] +ext2 !ext1 | |
32 # | |
33 # E.g. | |
34 # | |
35 # make_ext.pl "MAKE=nmake -nologo" --dir=..\ext | |
36 # | |
37 # make_ext.pl "MAKE=nmake -nologo" --dir=..\ext --target=clean | |
38 # | |
39 # make_ext.pl MAKE=dmake --dir=..\ext | |
40 # | |
41 # make_ext.pl MAKE=dmake --dir=..\ext --target=clean | |
42 # | |
43 # Will skip building extensions which are marked with an '!' char. | |
44 # Mostly because they still not ported to specified platform. | |
45 # | |
46 # If any extensions are listed with a '+' char then only those | |
47 # extensions will be built, but only if they aren't countermanded | |
48 # by an '!ext' and are appropriate to the type of building being done. | |
49 # An extensions follows the format of Foo/Bar, which would be extension Foo::Bar | |
50 | |
51 # It may be deleted in a later release of perl so try to | |
52 # avoid using it for other purposes. | |
