HOSTCFLAGS is an environment variable. See Documentation/kbuild/kbuild.rst HOSTCFLAGS ---------- Additional flags to be passed to $(HOSTCC) when building host programs. If you do not want to type it every time, add the following to ~/.profile or ~/.bashrc, etc. export HOSTCFLAGS="$(pkg-config --cflags bee-headers) -D_UUID_T -D__GETHOSTUUID_H" Or, if you want to limit this HOSTCFLAGS definition only to a specific kernel tree, you can add GNUmakefile to wrap Makefile. This is how people often add local setups without typing a long command. GNUmakefile: export HOSTCFLAGS = $(shell pkg-config --cflags bee-headers) -D_UUID_T -D__GETHOSTUUID_H include Makefile Then, you do not need to bother the upstream kernel. > We can detect we are in a non-linux based environment and enable a > Makefile <VAR> (e.g., NOLINUX=1) and handle the NOLINUX build case > (with pkg-config/bee-headers) inside the Makefiles for these non-linux > cases.
