I am not sure if this answers your question but to build a 2.6 Linux kernel using the buildroot uclibc ppc cross compiler you would issue the following make command
make ARCH=ppc CROSS_COMPILE=powerpc-linux-uclibc- If you were using the crosstools compiler rather than buildroot, the CROSS_COMPILE value would change. For older version of GCC it might require a full path to the crosscompiler. If you are building a BSP in the powerpc tree use ARCH=powerpc I am fairly certain that when you are building a Linux kernel it is irrelevant whether you use a glibc or uclibc or ... compiler. The kernel is not going to link against any standard C library, those library functions the kernel uses must be coded in the kernel. However, when you are cross compiling applications for your target it is a good idea to stick to the same standard C library and associated cross compiler. rodolfo wrote: > I'm sorry. > > I want build kernel linux 2.6 for ml403. > Did I have to change the predefined compiler flags for ppc_4xx?
