Previously klibc $(objtree)/.config depended on the kernel output directory. This would cause 'defconfig has changed, please remove or edit .config' build errors if $(KLIBCKERNELOBJ) directory was modified. This directory dependency is a false dependency that does not indicate that the target, $(objtree)/.config, ne...

We currently use KLIBCKERNELSRC and KLIBCKERNELOBJ variables which used to be required to point to a kernel source and object directories. However the kernel headers were reorganised starting in Linux 3.7 such that that doesn't work properly. This series removes KLIBCKERNELOBJ and changes the use and documentation of KLIBCKERNELSRC to be consistent. Ben. Ben Hutchings (4): [klibc]

The following patchset implements 3 seperate series of changes. External Building ================= Patches 1 through 8 enable to use of klibc's build system while leaving the src tree pristine (and potentially read only). Specifically: - srctree=<Sources for klibc> - objtree=<Ouput directory for klibc> - KLIBCKERNELSRC=<Kernel sources> - KLIBCKERNELOBJ=<Kernel output directory> As an example, with these patches, one can call 'make' as follows (assuming /usr/local/src/linux-2.6 are kernel sources and object files and /usr/local/src/klibc a...
