After configuring ppc-source, a make boot fails to complete with errors about zlib.h missing. Copying /usr/src/linux/arch/ppc/boot/include/zlib.h to /usr/src/linux/arch/ppc/boot/lib/ fixed the problem. Reproducible: Always Steps to Reproduce: 1. emerge ppc-sources 2. make menuconfig 3. make boot Actual Results: make boot fails with errors about missing zlib.h Expected Results: built vmlinuz
ppc-sources has been updated since long, closing this bug.
