Hello all, I was building gcc 3.2 as a cross-compiler from i686 linux to mips-sgi-irix6.5. I used the following configure command: ./configure --target=mips-sgi-irix6.5 --with-bfd-assembler --with-gnu-as --with-gnu-ld --program-suffix=-mips --prefix=/home/dimav/mipsgcc --enable-targets=mips-sgi-irix6.5 Binutils configured and built fine, I configured the gcc 3.2 core, but when I did make, i got the following error: /include -g -DIN_LIBGCC2 -D__GCC_FLOAT_NOT_NEEDED -Dinhibit_libc -I. -I. -I. -I./. -I./config -I./../include -DL_muldi3 -c ./libgcc2.c -o libgcc/./_muldi3.oas: unrecognized option `-O0' make[2]: *** [libgcc/./_muldi3.o] Error 1 What went wrong, and is there a way for me to create a MIPS cross-compiler for i686-linux by using GCC 3.2? Thanks for everybody's help.
