By this libmudflap got configured for x86/linux target. Now I built the gcc compiler for (RENESAS)sh-elf target and tried to configure the libmudflap by this method. However I got the same error "error: [configure-target-libmudflap]". So I followed following steps for libmudflap configuration: I created a separate build folder and from there a) [libmudflap source path]/configure --target=sh-elf --prefix=[My prefix folder path] b) make c) make install By this, libmudflap.a got created but for i386-redhat-linux target. Is it the case that, libmudflap does not support the sh-elf target? Regards, Deepen Mantri KPIT Cummins InfoSystems Ltd.
