When compiling any gentoo-sources-2.6.32 with gcc-4.4.4 (or any spec of gcc-4.4.4-r1) on 32-bit userland ppc, the build fails with CC arch/powerpc/platforms/chrp/setup.o cc1: warnings being treated as errors arch/powerpc/platforms/chrp/setup.c: In function 'chrp_event_scan': arch/powerpc/platforms/chrp/setup.c:378: error: the frame size of 1040 bytes is larger than 1024 bytes make[2]: *** [arch/powerpc/platforms/chrp/setup.o] Error 1 make[1]: *** [arch/powerpc/platforms/chrp] Error 2 make: *** [arch/powerpc/platforms] Error 2 This is apparently a long standing bug and was hit by Coviello at cruxppc.org for >=2.6.31. See http://article.gmane.org/gmane.linux.ports.ppc64.devel/61517/match= This problem does not affect gcc-4.3*. You can also work around this problem by disabling CONFIG_PPC_CHRP which may be undesirable. Reproducible: Always Steps to Reproduce: 1. emerge =sys-devel/gcc-4.4.4 (or 4.4.4-r1) 2. emerge gentoo-sources (currently 2.6.32-r7 is stable on ppc) 3. compile kernel

Post a make V=1 build log please. Does it work if you turn off -Werror?
i see no indication this is a bug in gcc. find the fix that went into upstream, or disable the config option as suggested. i doubt you'll find anyone here that would actually write a fix if upstream hasnt done it.
If you turn off -Werror by setting CONFIG_PPC_DISABLE_WERROR=y you get past the error. I'm going to close this RESOLVED INVALID but will continue to poke around and post here if I find more for the records.
