Compile mingw32 libs with emerge

[andreas99]

Hello,

I've build a mingw32 compiler in gentoo. Now I could build win32 binaries. But many libraries in win32 format are missing for real world application. For example boost. Is it possible to compile boost in portage for mingw32? Or do I have to compile all libs beside portage?

I've seen here[1] a tutorial with ARCH="arm". But it seems there's no ARCH="mingw32". With xmingw before it was easier to get some basic mingw32 packages compiled and up-to-date. Is there a similar way with crossdev?

Now I found two tutorials:

http://gentoo-wiki.com/HOWTO_MinGW
http://www.gentoo.org/proj/en/base/embedded/cross-development.xml

I made it exact as explained. Now I like to xmerge glibc:

> xmerge -vp glibc

Calculating dependencies... done!
[ebuild N ] sys-libs/timezone-data-2007k to /usr/i686-mingw32/ USE="-elibc_FreeBSD -elibc_glibc -nls" 0 kB
[ebuild N ] sys-libs/glibc-2.6.1 to /usr/i686-mingw32/ USE="-debug -gd -glibc-omitfp -hardened -multilib -nls -profile -selinux -vanilla" 16,007 kB

But then it dies with:

>>> Compiling source in /var/tmp/portage/sys-libs/timezone-data-2007k/work ...

Ok, where is sys/wait.h

> epm -qf /usr/include/sys/wait.h
glibc-2.6.1

I need timezone-data to compile glibc and I need glibs to compile timezone-data on mingw32.

Maybe I installed the toolchain not complete. Any ideas or hints?
