Good evening, I'm trying to configure gcc 3.4.5 to be cross compiler with i686 as host and powerpc-wxworks (with altivec support) as target. I'm working under msys and I'm using the mingws's compiler (gcc
3.4.2). I have lunched configure command as:../configure --with-gcc --with-gnu-ld --with-gnu-as --with-gnu-ar
--enable-threads --target=powerpc-vxworks --enable-language=c,c++
--enable-altivec --disable-install-libiberty --without-headers
The configure command generates a Makefile, and the report is the follow:
creating cache ./config.cache checking host system type... i686-pc-mingw32 checking target system type... powerpc-wrs-vxworks checking build system type... i686-pc-mingw32 checking for a BSD compatible install... /bin/install -c

It sounds as the vxWorks configuration isn't correct! Have you any idea or suggests?
