I downloaded and installed cygwin, version of cygwin1.dll is 1.5.12-1. I downloaded gcc-3.4.3 sources, gcc-3.4.3.tar.gz, and unpacked it to /home/gcc-3.4.3 Then I wanted to build a gcc cross-compiler for target powerpc-eabi (mpc5xx) I used this to configure: @ /home/gcc-3.4.3: mkdir obj @ /home/gcc-3.4.3: cd obj @ /home/gcc-3.4.3/obj: ../configure --prefix=/usr/local --with-gnu-as --with-gn u-ld --disable-threads --with-cpu=powerpc --enable-languages=c,c++ --target=pow erpc-ppc-eabi I even tried this: @ /home/gcc-3.4.3/obj: ../configure --prefix=/usr/local --with-gnu-as --with-gn u-ld --disable-threads --with-cpu=powerpc --enable-languages=c,c++ --target=pow erpc-eabi
and I issued make: @ /home/gcc-3.4.3/obj: make Then I got this error message (in both configure cases) ... /home/gcc-3.4.3/obj/gcc/xgcc -B/home/gcc-3.4.3/obj/gcc/ -B/usr/local/powerpc-ppc -eabi/bin/ -B/usr/local/powerpc-ppc-eabi/lib/ -isystem /usr/local/powerpc-ppc-ea bi/include -isystem /usr/local/powerpc-ppc-eabi/sys-include -O2 -DIN_GCC -DCROS S_COMPILE -W -Wall -Wwrite-strings -Wstrict-prototypes -Wmissing-prototypes -W old-style-definition -isystem ./include -g -DIN_LIBGCC2 -D__GCC_FLOAT_NOT_NE EDED -Dinhibit_libc -I. -I. -I../../gcc -I../../gcc/. -I../../gcc/../include -I. ./intl -mrelocatable-lib -mno-eabi -mstrict-align -DL_muldi3 -c ../../gcc/libgc c2.c -o libgcc/./_muldi3.o as: unrecognized option `-mppc' make[2]: *** [libgcc/./_muldi3.o] Error 1 make[2]: Leaving directory `/home/gcc-3.4.3/obj/gcc' make[1]: *** [stmp-multilib] Error 2 make[1]: Leaving directory `/home/gcc-3.4.3/obj/gcc' make: *** [all-gcc] Error 2 which as gives the following: /usr/bin/as as --version gives the following: @ /home/gcc-3.4.3/obj: as --version GNU assembler 2.15.94 20041229 Copyright 2002 Free Software Foundation, Inc.
