[RESOLVED] Crosscompiling from Linux for Windows

[MarcoBi]

Hi Devs,
I'm currently attempting to cross compile latest git version (20/09/2010) from a custom Linux toolchain (MinGW-Cross-Env) to Windows.

with a

Code: [Select]

SDL_LIBS="`/opt/mingw/usr/i686-pc-mingw32/bin/sdl-config --libs` -lrtmp -lz -lws2_32 -lwinmm -lssl -lgdi32 -lcrypto -lws2_32 -lgdi32 -lcrypt32 -lz -lfreetype -lwinmm" ./configure --host='i686-pc-mingw32' --with-curl-config=/opt/mingw/usr/i686-pc-mingw32/bin/curl-config
I get this error while linking:

Ehm... to tell the truth I have _timeBeginPeriod@4 defined in winmm.a, anyway do I need to put -lwinmm in a particular place?

Thanks!

[Mattn]

well - i don't know about that linking problem - maybe add the -lwinmm stuff to build/plattform_specific.mk

it would be very nice if you could test the patch for the new build system with mingw-cross-env. the patch is at http://mattn.ninex.info/files/newbuildsystem.diff

Do I need to apply it to latest git? I'm asking because of lot of "rejected" errors... { Reversed (or previously applied) patch detected!  Assume -R? [n] } 

[bayo]

I dont check to patch, but it is not yet applied to the repository.

[Mattn]

yes, you have to apply it - but try to use git apply patch.diff

I have only static libraries, so... do I need shared libraries? (that's not the case of mingw cross env)

Best reagrds

[Mattn]

yes, in mingw32.mk is the pkg-config call for the libs of gtkglext missing.

[Mattn]

btw. please post a diff when you fixed something on the makefile, not the full file.

[MarcoBi]

Here is the patch for my modified mingw32.mk Makefile.

Can I repost my compilation attempt when I'll rebuild a shared version of the GTK stack in my cross compile env?

Bye!

It's not missing, I have

Code: [Select]

GTK_GLEXT_CFLAGS         ?= $(call PKG_CFLAGS,gtkglext-1.0)
GTK_GLEXT_LIBS           ?= $(call PKG_LIBS,gtkglext-1.0)
Bye

[Mattn]

you should add your the mingw-cross-env bin dir to your path then you don't have to patch the makefiles (see Makefile.local)

about the missing libs for mingw - that should not be added like this but like this:

Code: [Select]

ufo_LDFLAGS              += -lws2_32 -lwinmm -lgdi32 -lintl -lfreetype
ufoded_LDFLAGS           += -lws2_32 -lwinmm -lgdi32
testall_LDFLAGS          += -lwinmm -lgdi32
ufo2map_LDFLAGS          += -lwinmm
ufomodel_LDFLAGS         += -lwinmm
uforadiant_LDFLAGS       += -lglib-2.0 -lgtk-win32-2.0 -lgobject-2.0


[Mattn]

there is still a problem in the makefiles about linking, even if i only type "make ufo" the game.so/dll is linked again.

I prefer to keep isolated a program I use to get a x-compiled binary from a x-compiled binary itself but you're right... keeping everythin in $PATH is a lot easier to manage!
Also if I don't add -lstdc++ in uforadiant_LDFLAGS I get a very long list of errors as shown in this attachment

OK, the new build system now works for me.
Just for reference:
- build shared GTK
- add -lstdc++ for uforadiant & uforadiant-brushexport

Now I only need to find how to compile maps and to find a way to package everything!

[Mattn]

what is -lrtmp?
