Hello,
while trying to debug a problem using git bisect, I am now at a point
where I cannot build the kernel at all. This is the error message I
get:
$ LANG=C make ARCH=powerpc \
CROSS_COMPILE=powerpc-linux- \
CONFIG_MODULE_COMPRESS_GZIP=true \
INSTALL_MOD_STRIP=1 CONFIG_MODULE_COMPRESS=1 \
-j4 INSTALL_MOD_PATH=$BOOT INSTALL_PATH=$BOOT \
CONFIG_DEBUG_INFO_COMPRESSED=1 \
install modules_install
make[2]: *** No rule to make target 'vmlinux', needed by
Surprising.
Did you make any change to Makefiles ?
No
Are you in the middle of a bisect ? If so, if the previous builds
worked, I'd do 'git bisect skip'
Yes, the previous one worked.
What's the result with:
LANG=C make ARCH=powerpc CROSS_COMPILE=powerpc-linux- vmlinux
$ LANG=C make ARCH=powerpc CROSS_COMPILE=powerpc-linux- vmlinux

cc1: some warnings being treated as errors
make[1]: *** [scripts/Makefile.build:267: kernel/module.o] Error 1
make: *** [Makefile:1735: kernel] Error 2
So, should I 'git bisect skip'?
Ah yes, I had the exact same problem last time I bisected.
So yes do 'git bisect skip'. You'll probably hit this problem half a
dozen of times, but at the end you should get a usefull bisect anyway.
