The manual says of AC_PATH_X (emphasis added): If either method is successful, set the shell variables `x_includes' and `x_libraries' to their locations, *unless they are in directories the compiler searches by default*.
On my Fedora 9 x86_64 system, I've noted that x_libraries is getting set to /usr/lib64. As this is a directory that the linker searches by default, I would have expected x_libraries to be empty. -- Braden McDaniel e-mail: <[EMAIL PROTECTED]> <http://endoframe.com> Jabber: <[EMAIL PROTECTED]>
