Created attachment 134932 [details] config.log I'm trying to build GnuTLS from sources on Fedora 26, x64. libtasn1 is installed in /usr/local (/usr/local/include and /usr/local/lib64). The issue does not occur on Ubuntu 17 x86_64, where libraries are installed in /usr/local/lib. Configure claims it cannot be found: checking for LIBTASN1... no configure: error: libtasn1 not found. Building without it results in significant loss of functionality. To proceed use --without-libtasn1 Failed to configure p11-glue I've tried --with-libtasn1=/usr/local and --with-libtasn1-prefix=/usr/local with no joy. Configure --help does not list them, but I thought it was worth a try. ************************************************** $ cat config.log This file contains any messages produced by compilers while running configure, to aid debugging if configure makes a mistake.

Also see "Install to lib64", https://lists.gnu.org/archive/html/automake/2009-01/msg00043.html. I'm using --libdir=/usr/local/lib64 as detailed in the thread.
GnuTLS has the same issue on Fedira - it can't find things in lib64/ directories. Fedora's gnutls.spec file actually runs sed over the configure script (thnaks NM): http://pkgs.fedoraproject.org/cgit/rpms/gnutls.git/tree/gnutls.spec Using sed seems wrong. I'm not an Autotools guy, but this seems like something Autoconf should handle for us. I'm trying to learn how things should be handled at https://lists.gnu.org/archive/html/autoconf/2017-10/msg00000.html.
