As the Freetz router project had to deal with BE/LE issues, we (yes, I was more active these days) decided to define the Kconfig logic in: extra/Configs/Config.mips ...and added the the CPU_FLAGS-* (CPU optimization etc.) stuff to... Rules.mak Please see the patch in [1] for more details. - Sedat - [1] http://freetz.org/browser/trunk/toolchain/make/target/uclibc/0.9.33.2/100-fritzbox_specific_arch_flags.freetz.patch _______________________________________________ uClibc mailing list uClibc@uclibc.org http://lists.busybox.net/mailman/listinfo/uclibc
