Sorry folks, this question seemed so simple, but obviously thinking "auto" differs a lot from what I was used to. Shame on me, but the docs did not reveal an answer.
Consider my configure.in contains ---------------------------------- # diet headers? AC_MSG_CHECKING([path to diet headers (http://diet.sf.net/)]) AC_ARG_WITH(diet, AC_HELP_STRING([--with-diet=DIET_PREFIX], [place where diet headers reside]), [ DIETDIR="$withval"; echo $withval; ], AC_MSG_ERROR([Please rerun using flag --with-diet=DIET_PREFIX ]) ) CPPFLAGS="-I$DIETDIR $CPPFLAGS" -------------------------------------- Now in my Makefile.am I want to do 2 things: First of all I want to add $DIET to VPATH Second: I want to use $DIET e.g in other definitions: test_linalg_SOURCES = $(DIET)/demos/linalg/TestLinalg.C But somehow variable DIET is not propagated from configure.in to Makefile.am. Is there a workaround for this? Any solutions welcome, best regards, Markus
