ok, i've sort of isolated an error that's causing me grief and it might either cause more general problems than just for my combination, or i could just be an idiot. once again, trying to build sh3eb toolchain with the absolute latest and greatest parts (including an SH-ified 2.6.13 kernel source tree). i can build the toolchain *and* compile the kernel if i do it in stages: * build the toolchain using the sanitized headers (no kernel source) * augment PATH to include new toolchain executables * export CROSS_COMPILE=sh3eb-unknown-linux-gnu- * configure kernel source tree with fairly generic config file * go to top of kernel source tree and "make ARCH=sh zImage" the above works just fine, so we know it can be done in stages. (SIDE NOTE: previously, to select sh3eb, i had the following line in the .dat file: TARGET_CFLAGS="-O -m3 -mb" however, based on this excerpt from arch/sh/Makefile: cflags-y := -mb cflags-$(CONFIG_CPU_LITTLE_ENDIAN) := -ml ... cflags-$(CONFIG_CPU_SH3) += -m3 it appears that i can delete those two -m flags and it won't make any difference, so i dropped them and it still worked.) now, since it can be done in stages, i tried to do it all at once. i changed the crosstool config files to point at the kernel source tree and the kernel config file. i also (could this have been a mistake?) unset CROSS_COMPILE and removed the crosstool bin directory from PATH, and started the build. after a short while (and about 60,000 lines of output), i got the following error: ... + KERNEL_PATCHLEVEL=6 + case "$KERNEL_VERSION.$KERNEL_PATCHLEVEL.x" in + case $ARCH in + make ARCH=sh prepare include/linux/version.h SPLIT include/linux/autoconf.h -> include/config/* CC scripts/mod/empty.o cc1: error: invalid option â'b' cc1: error: invalid option â'3' make[2]: *** [scripts/mod/empty.o] Error 1 make[1]: *** [scripts/mod] Error 2 make: *** [scripts] Error 2 what that tells me is that the perfectly valid SH3 options -mb and -m3 are unrecognized, which further suggests that the wrong compiler is being used since it doesn't recognize SH3-specific options. what have i misunderstood here? how are those option settings getting in the way, because that's clearly what's happening. thoughts? rday p.s. uh oh ... i think i have a glimmer ...
