From dcc2da1a9693807096e9ac5137b499a829c51268 Mon Sep 17 00:00:00 2001 From: Sam Ravnborg Date: Sat, 25 Oct 2008 22:58:23 +0200 Subject: [PATCH] kbuild: improve check-symlink o if include/asm point to a nonexisting directory remove the asm symlink o if include/asm is a directory error out This fixes a situation where one could be left with a symlink to asm-x86 but that directory no longer exist and thus the build would error out. include/asm may be a directory if the kernel tree has been copied Signed-off-by: Sam Ravnborg --- Makefile | 5 +++++ 1 file changed, 5 insertions(+) diff --git a/Makefile b/Makefile index a7f2068..ffac712 100644 --- a/Makefile +++ b/Makefile @@ -961,6 +961,7 @@ export CPPFLAGS_vmlinux.lds += -P -C -U$(ARCH) # The asm symlink changes when $(ARCH) changes. # Detect this and ask user to run make mrproper +# If asm is a stale symlink (point to dir that does not exist) remove it define check-symlink set -e; \ if [ -L include/asm ]; then \ @@ -970,6 +971,10 @@ define check-symlink echo " set ARCH or save .config and run 'make mrproper' to fix it"; \ exit 1; \ fi; \ + test -e $$asmlink || rm include/asm; \ + elif [ -d include/asm ]; then \ + echo "ERROR: $@ is a directory but a symlink was expected";\ + exit 1; \ fi endef -- 2.7.4
