[gentoo-embedded] problems crosscompiling libX11

[David Thomas]

I've been having problems with libX11.  First it tries to build a binary
with the crosscompiler then execute it:

/bin/sh: ../src/util/makekeys: cannot execute binary file

I wrote a patch that fixes this... See below.

I'm still having a problem with libtool.  The last step of the build process
it does the following:
/bin/sh ../libtool --mode=link armv5l-softfloat-linux-uclibc-gcc ... -L /newroot/usr/lib ...
...(much more)... -lXau -lXdmcp -ldl

This calls the crosscompiler replacing -lXau and -lXdmcp with /usr/lib/libXau.so and
/usr/lib/libXdmcp.so INSTEAD of the crosscompiled ones in /newroot/usr/lib

Same thing even if I hardcode values in ../libtool for sys_lib_search_path_spec.
I also tried setting an LDPATH in /etc/env.d/05crosscompiler.

Am I missing something in /etc/ld.so.conf environment?

Thanks!

Here are the fixes:
Added to ebuild (is this right? comments? it seems to work):
src_unpack()
{
        x-modular_unpack_source
        x-modular_patch_source
        cd ${S}
        epatch /path/to/patchfile
        x-modular_reconf_source
}
