Compilation problem on sparc64

Postby linkfanel » Mon Feb 12, 2007 9:18 am

A 2.6.19.3 kernel patched with the latest grsecurity-2.1.10-2.6.19.3-200702061822.patch (at least) fails to compile on sparc64:

Code: Select all
  CC      arch/sparc64/kernel/setup.o
cc1: warnings being treated as errors
arch/sparc64/kernel/setup.c:64: warning: missing initializer
arch/sparc64/kernel/setup.c:64: warning: (near initialization for 'screen_info.lfb_width')

make[2]: *** [arch/sparc64/kernel/setup.o] Erreur 1
make[1]: *** [arch/sparc64/kernel] Erreur 2


Indeed, arch/sparc64/kernel/Makefile and arch/sparc64/mm/Makefile contain the "EXTRA_CFLAGS := -Werror" flag. Those warnings do not appear on a vanilla kernel. The complete list of problematic warnings is (when commenting the flag):

thanks for the list, but in the end i ended up removing -Werror instead, it's the easier way out.
