I am attempting to compile gcc, configured as a cross compiler. I explicitly do not have libgmp, libmpfr, or libmpc installed on my system. The documentation at http://gcc.gnu.org/wiki/InstallingGCC indicates that I may compile these libraries as part of the gcc compilation process overall. To cut a long story short: $ tar -xjf gcc-4.8.2.tar.bz2 $ mkdir objdir $ cd gcc-4.8.2/ $ contrib/download_prerequisites ... [sources downloaded, extracted, symlinks created] ... $ cd ../objdir/ $ ../gcc-4.8.2/configure \ --target=avr \ --enable-languages=c \ --prefix=/home/sam/local ... $ make ... [compilation proceeds for a while] ... configure: error: cannot compute suffix of object files: cannot compile See `config.log' for more details. make[1]: *** [configure-target-libgcc] Error 1 make[1]: Leaving directory `/home/sam/objdir' make: *** [all] Error 2 The error is logged in objdir/avr/libgcc/config.log. I understand this indicates that the prerequisite libraries weren't set up correctly prior to the compilation? Further, no compiled libraries (static or dynamic) seem to be present in objdir/. Why do the dependent libraries not seem to be compiled as per the above wiki document? Was there a configure script flag I needed to pass to tell the compiler to also compile the dependent libraries? Thanks for any insight you might have.
