Hi, I'm wondering. I'm trying to use AC_LINK_IFELSE to link a small program against libexpat. I set the flags LIBS="$LIBS $EXPAT_LDADD" CPPFLAGS="$CPPFLAGS $EXPAT_INCLUDES" LDFLAGS="$LDFLAGS $EXPAT_LDFLAGS" appropriatly. The problem is, I use the program to determine if libexpat has been compiled already. If that doesn't work, I go ahead and ./configure && make the libexpat that i've packed in my distro. Now, if libexpat is already installed on the system, this test always passes, because gcc finds it in the standard location. Is there anything I can do to force gcc and autoconf to link that program and only use the libraries and headers that I give it?
