When I added the -print-sysroot option to see what gcc was thinking was the sysroot setting it revealed this: WITH -m4 option: $ sh4-oe-linux-gcc -ml -m4 --sysroot=sysroots/sh775x-oe-linux -print-sysroot sysroots/sh775x-oe-linux/m4 WITHOUT -m4 option: $ sh4-oe-linux-gcc -ml --sysroot=sysroots/sh775x-oe-linux -print-sysroot sysroots/sh775x-oe-linux It appears some arguments are getting mangled and somehow the m4 option is concatinated to the end of the sysroot. My workaround was to add symlink sysroots/sh775x-oe-linux/m4 to point to "./". $ sh4-oe-linux-gcc --version sh4-oe-linux-gcc (GCC) 4.7.2 ^ permalink raw reply [flat|nested] 4+ messages in thread

I'm also using symbolic links for those issues and have no good idea for multilibs handling itself. Clearly a true fix will be welcome, though our handling/setting for SH multilibs looks a bit too complicated already. ^ permalink raw reply [flat|nested] 4+ messages in thread
