Actually on the good build it seems the -I wasn't there at > all. I tracked it down now (a simple bisect would have doen the trick too). It was the introduction of KBUILD_EXTRA_SYMBOLS that caused us troubles because we started to include the Makefile in Makefile.modpost and thus ccflags-y (EXTRA_CFLAGS) were assigned the value "-I$(src)" but $(src) was not defined so we ended up with an empty -I which then picked up the following parameter on the command line. I cooked up the following fix: diff --git a/scripts/Makefile.modpost b/scripts/Makefile.modpost index a098a04..28ef233 100644 --- a/scripts/Makefile.modpost +++ b/scripts/Makefile.modpost @@ -37,6 +37,10 @@ # symbols in the final module linking stage # KBUILD_MODPOST_NOFINAL can be set to skip the final link of modules. # This is solely usefull to speed up test compiles + +# Assign src as it may be used in ccflags-y +src = . + PHONY := _modpost _modpost: __modpost Please let me know if this solves your problem or more issues reamin.
