I need the libraries for some executables, not all. But perhaps you know something about my project that I don't. If that's the case, please tell me more. In the meantime, I noticed Bob uses things like: LIB_MATH='' AC_CHECK_LIB(m,sqrt,LIB_MATH="-lm",,) LIBS="$LIB_MATH $LIBS" AC_SUBST(LIB_MATH) in the configure.ac, so I'm inclined to write a macro that I can use like this: LIB_MATH='' AC_SUBST([LIB_MATH]) ... FOO_SEARCH_LIB([LIB_MATH], [sqrt], [m], [AIF], [AINF], [OL]) and FOO_SEARCH_LIB would expand to something like: AC_SEARCH_LIBS([sqrt], [m], [case "$ac_cv_search_sqrt" in 'none required') ;; 'no') ;; *) LIB_MATH="$ac_cv_search_sqrt $LIB_MATH" ;; esac [AIF]], [AINF], [OL]) and I bet I blew some of the quoting...
