From edb950c17de09ed04be1ed2c451ba207e3b0a29b Mon Sep 17 00:00:00 2001 From: Masahiro Yamada Date: Wed, 16 Jul 2014 16:12:20 +0900 Subject: kbuild: fix a bug of C++ host program handling The comment claims: C++ executables compiled from at least one .cc file and zero or more .c files But C++ executables with zero .c file fail in build. For example, assume we have a Makefile like this: hostprogs-y := foo foo-cxxobjs := bar.o In this case, foo is treated as host-csingle and Kbuild tries to search non-existing foo.c source.
