in 2.6.31, it is no longer possible to build kernel modules for some platforms (the ones that need include2) outside the kernel src tree if the src tree was built using O= to specify an alternate directory for the build output. i think this broke with the following commit: commit b8b572e1015f81b4e748417be2629dfe51ab99f9 Author: Stephen Rothwell <sfr@xxxxxxxxxxxxxxxx> Date: Fri Aug 1 15:20:30 2008 +1000 powerpc: Move include files to arch/powerpc/include/asm when the platform specific include directories were shuffled around without updating the top level Makefile. however, i think this FAIL is generic, and not limited to powerpc. here's a patch to the top level Makefile to teach it about the shuffled files: --- /local/caveh/linux/linux-2.6.31/Makefile 2009-09-09 15:13:59.000000000 -0700 +++ Makefile 2009-09-16 12:23:05.000000000 -0700 @@ -958,9 +958,9 @@ ifneq ($(KBUILD_SRC),) echo " in the '$(srctree)' directory.";\ /bin/false; \ fi; - $(Q)if [ ! -d include2 ]; then \ - mkdir -p include2; \ - ln -fsn $(srctree)/include/asm-$(SRCARCH) include2/asm; \ + $(Q)if [ ! -d include2 ]; then \ + mkdir -p include2; \ + ln -fsn $(srctree)/arch/$(SRCARCH)/include/asm include2/asm; \ fi endif -- To unsubscribe from this list: send the line "unsubscribe linux-kbuild" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
