Hi, I've been trying to build gcc 4.7.3 with C and Ada support for target powerpc-eabispe. I am using gcc-4.8.1 with gnat installed on a linux host. The problem I am facing is that when linking gnat1 I get undefined reference errors regarding symbols like __gnat_rcheck_CE_Explicit_Raise. I also trie to build a native gcc 4.7.3 with support for C and Ada but got the exact same result. Here is the configuration I am using : ../configure --prefix=/home/glabarthe/gcc/install --target=powerpc-eabispe --enable-languages=c,ada --disable-boostrap Does anyone already saw that kind of error ? Best regards. Guillaume.
