Hi, I want to compile gcc 4.9.0 as a cross compiler for the msp430 architecture. About the prerequisites ----------------------- Binutils 2.24 sources have been downloaded, a symbolic link "binutils" has been created in the gcc source dir. Then ... cd /usr/local/src/gcc-4.9.0 ./contrib/download_prerequisites mkdir /usr/local/src/gcc-4.9.0-build-msp430-elf cd /usr/local/src/gcc-4.9.0-build-msp430-elf ../gcc-4.9.0/configure --target=msp430-elf \ --prefix=/usr/local/msp430-elf --enable-languages=c,c++ make -j8 The whole output of configure is attached. The error --------- make of gcc fails with the following error: ... checking for msp430-elf-gcc... \ /usr/local/src/gcc-4.9.0-build-msp430-elf/./gcc/xgcc \ -B/usr/local/src/gcc-4.9.0-build-msp430-elf/./gcc/ \ -B/msp430-elf/bin/ -B/msp430-elf/lib/ \ -isystem /msp430-elf/include -isystem /msp430-elf/sys-include checking for suffix of object files... configure: error: \ in `/usr/local/src/gcc-4.9.0-build-msp430-elf/msp430-elf/libgcc': configure: error: cannot compute suffix of object files: cannot compile See `config.log' for more details. make[1]: *** [configure-target-libgcc] Fehler 1 make[1]: Leaving directory `/usr/local/src/gcc-4.9.0-build-msp430-elf' make: *** [all] Fehler 2 "cannot compute suffix ..." seems to be a common error message. I read that in the gcc faq, but didn't find a solution myself. Investigation of the problem ---------------------------- There are errors in /usr/local/src/gcc-4.9.0-build-msp430-elf/msp430-elf/libgcc/config.log: <snip> /usr/local/src/gcc-4.9.0-build-msp430-elf/./gcc/as: \ 106: exec: -mP: not found </snip> The corresponding file "config.log" is attached. Compiler & system info ---------------------- # gcc -v Using built-in specs.
