I've basically followed the documentation for embedded development (cross-compiling inside an x86 virtual machine towards a PowerPC uClibc (powerpc-gentoo-linux-uclibc) target) http://www.gentoo.org/proj/en/base/embedded/cross-development.xml I built myself a powerpc-gentoo-linux-uclibc toolchain, it all works and even makes working binaries. Then, basically did xmerge --root /cross/root system Which causes the libperl build (eventually) to complain; === Which of these apply? [linux] ./hints/linux.sh: line 126: ./a.out: cannot execute binary file You don't have an ELF gcc. I will use dld if possible. If you are === And so on. It goes on to say: === Checking your choice of C compiler and flags for coherency... I've tried to compile and run the following simple program: #include <stdio.h> .. and I got the following output: /usr/libexec/gcc/powerpc-gentoo-linux-uclibc/ld: cannot find -lgbdm collect2: ld returned 1 exit status I can't compile the test program === I believe the first error is quite prominently broken (since it shouldn't be running PPC binaries here!) and the second one worries me since it never tried to emerge libgdbm in the first place although I manually emerged it, it still doesn't find it, which I think is as these two bug: http://bugs.gentoo.org/show_bug.cgi?id=157774 http://bugs.gentoo.org/show_bug.cgi?id=157778 Any help would be really appreciated, it's quite important that the build process can be semi-automated this way and we'd rather use Gentoo standard tools and Catalyst etc. for building our system image than making our own.

(In reply to comment #2) > > *** This bug has been marked as a duplicate of bug 157778 *** > here are two different problems: 1) -lgbdm error that can be fixed with Diego's patch linked 2) execution of non-native binaries which is a complete different issue and is the title of the bugreport itself. As far as I am aware this bug shouldn't be marked as duplicate but should try to address cross compilation issues when this kind of checks happens.
