Cross-compilation: linking fail

I am trying to crosscompile mc for arm x11-less linux. That system has glibc 2.10 and linux 2.6.22
I think that is important, because it seems that something goes wrong with preprocessor's defines.

PS
What a shame that current stable (for a long time) version can't be compiled. So far I use mc-4.7.5.6 and try to upgrade from previous stable to current.

What a shame that developers cannot compile mc for any platforms that are existing in the Universe!

So far I use mc-4.7.5.6 and try to upgrade from previous stable to current.

Try to compile 4.8.1-stable branch from repo. After #2906, compilation should be successful.

It is not interesting at all. config.h is interesting instead.

Ok. I will try.

But nevertheless, here you are (see attached file).

[laborer]

So, compilation was successful. But I got linking error.
For some reason glib was not picked up.

and so on.
I pass GLIB_LIBS,GLIB_CFLAGS,GMODULE_CFLAGS,GMODULE_LIBS variables as parameters of configure script. They are present in Makefile. I see them. But they are not used! May be something important in linking mechanism changed since 4.7.5.6? Could you have a look at my Makefile please?

CCLD mc

Please, provide to us output of the command 'make V=1'

Hm.. I don't see glib in list of libraries. Which cross-platform framework you use? buildroot? crosstool-ng? How you compile GLib library? Where library is placed? Provide more info about your cross-build environment, please. I'll try to reproduce.

How I build mc

[laborer]

slavazanko,
I don't use buildroot or any other similiar framework. Buildroot was too buggy when I started. The other frameworks might be better but sometimes did not upgrade packages for a long time (for instance mc). So, I decided to build rootfs on my own. This means that I wrote several build scripts. I can control patches, compiler options, configure parameters and so on.
For compilation I use
arm-xscale-linux-gnueabi-gcc (crosstool-NG 1.12.0) 4.3.6
I think you can use any available arm crosscompiler.
For reproducing bug I have extracted from my build system some mc build related stuff.
So, there are 7 scripts: build.sh get.sh make_glib.sh make_libffi.sh make_mc.sh make_ncurses.sh make_zlib.sh

For starting build process just run ./build.sh from extracted archive. All required settings (version of each package, paths, common compilation options) are present in this file. I guess my code will tell you more than my words. Besides, keep in mind that there is no mc git support. You should clone required branch and pack it as release archive with name mc-4.8.1.6.tar.bz2
