7 # This script acts as a simple interface for building extensions.
9 # It's actually a cut and shut of the Unix version ext/utils/makeext and the
10 # Windows version win32/build_ext.pl hence the two invocation styles.
12 # On Unix, it primarily used by the perl Makefile one extention at a time:
14 # d_dummy $(dynamic_ext): miniperl preplibrary FORCE
15 # @$(RUN) ./miniperl make_ext.pl --target=dynamic $@ MAKE=$(MAKE) LIBPERL_A=$(LIBPERL)
18 # If '--static' is specified, static extensions will be built.
19 # If '--dynamic' is specified, dynamic (and nonxs) extensions will be built.
20 # If '--all' is specified, all extensions will be built.
22 # make_ext.pl "MAKE=make [-make_opts]" --dir=directory [--target=target] [--static|--dynamic|--all] +ext2 !ext1
26 # make_ext.pl "MAKE=nmake -nologo" --dir=..\ext
28 # make_ext.pl "MAKE=nmake -nologo" --dir=..\ext --target=clean
30 # make_ext.pl MAKE=dmake --dir=..\ext
32 # make_ext.pl MAKE=dmake --dir=..\ext --target=clean
34 # Will skip building extensions which are marked with an '!' char.
35 # Mostly because they still not ported to specified platform.
37 # If any extensions are listed with a '+' char then only those
38 # extensions will be built, but only if they arent countermanded
39 # by an '!ext' and are appropriate to the type of building being done.
41 # It may be deleted in a later release of perl so try to
42 # avoid using it for other purposes.
