[PATCH] kbuild: external module build warnings when KBUILD_OUTPUT set and W=1

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Commit db547ef19064 ("Kbuild: don't add obj tree in additional includes")
causes warnings (-Wmissing-include-dirs) when compiling external modules
with KBUILD_OUTPUT set and W=1.  This is because $src can be an absolute
path to the external module source which when prefixed with -I$(srctree)/
generates an incorrect directory path.
