Hi there,

Does anyone has working defconfig for a Mac Mini G4 ?

Here is what I tried:

$ cat ./arch/powerpc/configs/g4_defconfig
CONFIG_PPC_FPU=y
CONFIG_ALTIVEC=y
$ make ARCH=powerpc g4_defconfig
$ make -j8 ARCH=powerpc CROSS_COMPILE=powerpc-linux-gnu- V=1
set -e; : '  CHK     include/config/kernel.release'; mkdir -p

That is odd. Doing a quick git bisect:

$ git checkout 3298b690b21cdbe6b2ae8076d9147027f396f2b1
$ make -n ARCH=powerpc CROSS_COMPILE=powerpc-linux-gnu- -f ./Makefile
silentoldconfig V=1
+ make -n ARCH=powerpc CROSS_COMPILE=powerpc-linux-gnu- -f ./Makefile
silentoldconfig V=1
/bin/sh: line 0: [: -ge: unary operator expected
make -f ./scripts/Makefile.build obj=scripts/basic

I cannot make sense of this shell error, maybe this is unrelated but
things start breaking around this commit.

Even if I discard this shell error, the next error comes with:

433dc2ebe7d17dd21cba7ad5c362d37323592236 is the first bad commit

With:

Comments ?

Solution is:

$ rm .cache.mk

I guess the cache was not cleared in between my different kernel compilations.

Sorry for the noise
