I've been working on getting the Gtk2-Perl stack to compile under
MSWin32 without as much pain as there is now. Windows has something
called 'import libraries' [1], which currently I have to create by
hand when I compile Cairo and Glib in order to get Gtk2 to compile. I
create these import libraries by hacking up the Makefile and adding
something similar to this:
dlltool --input-def Cairo.def --dllname Cairo.dll --output-lib libCairoPerl.a
$(CP) libCairoPerl.a C:/camelbox/lib
I have been able to abstract the above and add it to the Makefile.PL
file. My questions right now are:
1) I created a dynamic_lib method in the Makefile.PL for
Cairo/Glib/Gtk2, and added Makefile code similar to the above. It
didn't work, as MakeHelper overrides my dynamic_lib method later on in
order to quiet things somewhere. I disabled dynamic_lib in MakeHelper
and my overridden dynamic_lib method gets fired. Is there a better
place for my extra code than the dynamic_lib method? Oh, I just
found the extra copy of MakeHelper.pm in the Glib source, I'm now
doing my sad panda face :(
2) What should I call my import libraries? I've been using
libGlibPerl, libCairoPerl and libGtk2Perl. They would only needed if
( $^O ~= /MSWin32/), they shouldn't be needed on cygwin or anywhere
else for that matter.
3) I was going to add a test in Makefile.PL to decide if the above
import libraries get added to the Makefile via
ExtUtils::Depends->set_libs, it would end up looking something like
this (taken from a patch I have made to the Gtk2 Makefile.PL):
use Config;
if ( $^O =~ /Win32/ ) {
$gtk2->set_libs (q(-L) . $Config{bin} . q( ) . $pkgcfg_gtk{libs}
. q(-lGlibPerl -lCairoPerl));
} else {
$gtk2->set_libs ($pkgcfg_gtk{libs});
}
Can someone think of a better way to do this? Is this not worth
pursuing at all because? Too much hassle?
My demo patches for the Makefile.PL included with Cairo/Glib/Gtk2 are
available at [2], [3] and [4]. They all work but only as long as
dynamic_lib has been disabled in $PERL5LIB/Glib/MakeHelper.pm (or
MakeHelper.pm in Glib source).
Thanks,
Brian
