Now I get almost the same error message at the console, but a different error in config.log: 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/ -nostdinc -B/usr/local/src/gcc-4.9.0-build-msp430-elf/msp430-elf/newlib/ -isystem /usr/local/src/gcc-4.9.0-build-msp430-elf/msp430-elf/newlib/targ-include -isystem /usr/local/src/gcc-4.9.0/newlib/libc/include -B/usr/local/src/gcc-4.9.0-build-msp430-elf/msp430-elf/libgloss/msp430 -L/usr/local/src/gcc-4.9.0-build-msp430-elf/msp430-elf/libgloss/libnosys -L/usr/local/src/gcc-4.9.0/libgloss/msp430 -B/usr/local/msp430-elf/msp430-elf/bin/ -B/usr/local/msp430-elf/msp430-elf/lib/ -isystem /usr/local/msp430-elf/msp430-elf/include -isystem /usr/local/msp430-elf/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 config.log snippet (whole file as attachment): /tmp/cctnz0X9.s: Assembler messages: /tmp/cctnz0X9.s:24: Error: unknown pseudo-op: `.refsym' Hope you can help me with this one, too.
