> I've configure GCC with: > > ../gcc-4.4.3/configure --target=sparc-edisoft-rtems --with-gnu-as > --with-gnu-as --without-newlib --disable-bootstrap --verbose > --enable-threads --enable-languages="c" > --prefix=/rtems/mcoutinho/ri/gcc-without-newlib/prefix I'm far from being an expert, but I suggest you the following things: - use a different triplet (the form should be sparc-vendor-os) - also specify the --build and --host arguments - drop one --with-gnu-as argument (you repeated it twice) - drop --disable-bootstrap, as it is implicit when building a cross-compilator - put --enable-languages=c instead of --enable-languages="c" - specify the --with-sysroot argument - make sure to build binutils before building gcc, and add the path to the binutils binaries to your PATH environment variable For more informations, please have a look at: - http://gcc.gnu.org/onlinedocs/gccint/Configure-Terms.html - http://gcc.gnu.org/install/configure.html
