Dear all, I can't imagine that I am the first to have this problem, but did not manage to find a solution in the manual or on the Internet: if I missed it, I apologize for that. In our project, we are using the superlu code. On some systems, the headers are present in <prefix>/include, on others in <prefix>/include/superlu. We therefore #include the files without the superlu/ part, as in "#include "slu_util.h" and append the directory <prefix>/superlu/ to the CPPFLAGS variable in our project. How can I achieve this with autoconf? I mean: I know how to write a test like AC_CHECK_HEADER(superlu/slu_util.h, foo, bar), but how do I obtain (in 'foo') the path relative to which the file superlu/slu_util.h was found? I was hoping that a variable, let's say 'header_location' is set, so I can implement 'foo' as something like: SUPERLU_CPPFLAGS="-I$header_location/superlu" Is there such variable? Or can this be accomplished in a different way? Your help is appreciated. With kind regards, Jan van Dijk. _______________________________________________ Autoconf mailing list Autoconf@xxxxxxx https://lists.gnu.org/mailman/listinfo/autoconf
