18 | # This script acts as a simple interface for building extensions. |

20 | # It's actually a cut and shut of the Unix version ext/utils/makeext and the |
21 | # Windows version win32/build_ext.pl hence the two invocation styles. |
22 | |
23 | # On Unix, it primarily used by the perl Makefile one extention at a time: |
a0d0e21e |
24 | # |
25 | # d_dummy $(dynamic_ext): miniperl preplibrary FORCE |
e2fabae1 |
26 | # @$(RUN) ./miniperl make_ext.pl --target=dynamic $@ MAKE=$(MAKE) LIBPERL_A=$(LIBPERL) |

28 | # On Windows or VMS, |
286d62c2 |
29 | # If '--static' is specified, static extensions will be built. |
a34ce875 |
30 | # If '--dynamic' is specified, dynamic extensions will be built. |
31 | # If '--nonxs' is specified, nonxs extensions will be built. |
286d62c2 |
32 | # If '--all' is specified, all extensions will be built. |
33 | # |
34 | # make_ext.pl "MAKE=make [-make_opts]" --dir=directory [--target=target] [--static|--dynamic|--all] +ext2 !ext1 |
35 | # |
36 | # E.g. |
37 | # |
38 | # make_ext.pl "MAKE=nmake -nologo" --dir=..\ext |
39 | # |
40 | # make_ext.pl "MAKE=nmake -nologo" --dir=..\ext --target=clean |
41 | # |
42 | # make_ext.pl MAKE=dmake --dir=..\ext |
43 | # |
44 | # make_ext.pl MAKE=dmake --dir=..\ext --target=clean |
45 | # |
46 | # Will skip building extensions which are marked with an '!' char. |
47 | # Mostly because they still not ported to specified platform. |
48 | # |
49 | # If any extensions are listed with a '+' char then only those |
50 | # extensions will be built, but only if they arent countermanded |
51 | # by an '!ext' and are appropriate to the type of building being done. |
