[patch 01/16] user-cppflags.patch

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

 



Without this patch there is no straight forward way to pass additional
CPPFLAGS at configure-time.  At TWW, everything non-vendor package is
installed to its own subdirectory, so we need the following to show
the preprocessor where the headers for the libraries we will link
later can be found:

	$SHELL ./configure \
	CPPFLAGS="-I${SB_VAR_CURL_INC}\
	 -I${SB_VAR_LIBEXPAT_INC}\
	 -I${SB_VAR_LIBZ_INC}\
	${CPPFLAGS+ $CPPFLAGS}" <<...>>
