I tried to crossbuild media-libs/freetype-2.3.4-r2 for arm-softfloat-linux-uclibc using the xmerge script provided in the Cross development guide (http://www.gentoo.org/proj/en/base/embedded/cross-development.xml) The host is a i486-pc-linux-gnu clean chroot (stage3 unpacked, emerge sync-ed, portage updated, installed crossdev for arm-softfloat-linux-uclibc). <eddyp> I found a bug when trying to cross compile freetype <eddyp> the configure script detects the i486-pc-linux-gnu-gcc as i486-pc-liunx-gnu <eddyp> no trailing -gcc and, of course, if fails to crossbuild <eddyp> I tried to configure by hand in the source directory the CC_BUILD variable and it(the configuration stage) works if overridden <eddyp> I don't know where to report this since I don't know if is an ebuild/package/toolchain issue <eddyp> this is what happens ... http://paste.debian.net/32916 <eddyp> I am trying to cross compile rrdtool for arm-softfloat-linux-uclibc Here is a listing that proves that CC_BUILD is valid workaround (I haven't checked the results, 'though) (chroot) twix freetype-2.3.4 # ./configure --prefix=/usr --host=arm-softfloat-linux-uclibc --mandir=/usr/share/man --infodir=/usr/share/info --datadir=/usr/share --sysconfdir=/etc --localstatedir=/var/lib --with-zlib --build=i486-pc-linux-gnu FreeType build system -- automatic system detection The following settings are used: platform unix compiler cc configuration directory ./builds/unix configuration rules ./builds/unix/unix.mk If this does not correspond to your system or settings please remove the file `config.mk' from this directory then read the INSTALL file for help.

Forgot to say, the package builds fine when exporting CC_BUILD
hmm, i don't have much time to look into this at the moment, but does something like this help? diff -Naur freetype-2.3.5-orig/builds/unix/configure.ac freetype-2.3.5/builds/unix/configure.ac --- freetype-2.3.5-orig/builds/unix/configure.ac 2007-07-02 15:41:39.000000000 -0600 +++ freetype-2.3.5/builds/unix/configure.ac 2007-07-17 22:48:08.000000000 -0600 @@ -40,7 +40,7 @@ # checks for native programs to generate building tool if test ${cross_compiling} = yes; then - AC_CHECK_PROG(CC_BUILD, ${build}-gcc, ${build-gcc}) + AC_CHECK_PROG(CC_BUILD, ${build}-gcc, ${build}-gcc) test -z "${CC_BUILD}" && AC_CHECK_PROG(CC_BUILD, gcc, gcc) test -z "${CC_BUILD}" && AC_CHECK_PROG(CC_BUILD, cc, cc, , , /usr/ucb/cc) test -z "${CC_BUILD}" && AC_MSG_ERROR([cannot find native C compiler])
Created attachment 125227 [details, diff] freetype-2.3.5-crossbuild.patch here's the full patch.
with this patch it compiles correctly. https://bugs.gentoo.org/attachment.cgi?id=125227
Applied to freetype-2.3.4-r2 and freetype-2.3.5. I've sent this patch upstream as well. Thanks for reporting.
