Hi Eduardo, > I'm using the following commands: > ./configure --target=mipsel-elf --prefix=/usr/local/ ... ..^^ As mentioned in the GCC documentation... http://gcc.gnu.org/install/ http://gcc.gnu.org/install/configure.html ...running configure in the self-same directory of the GCC source code is not supported. (Nor from any subdirectory within the GCC source code tree.) Your GCC source is likely tainted. You should rm -rf it, tar x fresh, and start from there. HTH, --Eljay
