You can simply build ia64 crosscompiler with (you don't need to install binutils): $ ../gcc-svn/trunk/configure --target=ia64-linux-gnu --enable-languages=c $ make [... the build will fail, but cc1 will be compiled correctly ... ] ~/gcc-build-ia64/gcc/cc1 -O3 -quiet pr42196-2.c pr42196-2.c: In function foo: pr42196-2.c:10:7: internal compiler error: in vectorizable_operation, at tree-vect-stmts.c:1989 Please submit a full bug report, with preprocessed source if appropriate.
