There are two things I am not quite clear on from the autoconf and automake documentation, and hoped to get some pointers on what is considered ?best practice?: (1) If I have flags that I do not want overridden by users when configure is executed, it seems like the recommendation is to place those flags in variables such as AM_CFLAGS and AM_LDFLAGS. But what wasn't clear was whether or not it was kosher, or recommended, or bad practice to set the values of these in configure.ac as a result of some tests and then AC_SUBST([...]) those variables at the end of configure.ac so that they are written to the Makefile. What is the current recommended practice? (2) If I want to add includes (e.g., "-I/path/to/include" to only certain modules within my build tree where they apply, how do I go about it? My concern is that thinks like foo_CPPFLAGS overrides the CPPFLAGS setting, and I want to add the includes, not override the defaults. Thanks in advance, Greg -- J.
