Hi folks! This bug is eerily similar to this one: https://issues.apache.org/bugzilla/show_bug.cgi?id=15679 except that failure occurs when invoking 'make', not when running './configure.' To be clear, if your '<Layout blah>' line is the first line of the file, make will fail with a libtool-related error. The following is the end of the build output. This is Ubuntu 10.10, Apache 2.4.2: make[2]: Entering directory `/home/ubuntu/matt/apache_foolings/httpd-2.4.2/os' make[3]: Entering directory `/home/ubuntu/matt/apache_foolings/httpd-2.4.2/os/unix' make[3]: Leaving directory `/home/ubuntu/matt/apache_foolings/httpd-2.4.2/os/unix' make[2]: Leaving directory `/home/ubuntu/matt/apache_foolings/httpd-2.4.2/os' make[2]: Entering directory `/home/ubuntu/matt/apache_foolings/httpd-2.4.2/server' make[3]: Entering directory `/home/ubuntu/matt/apache_foolings/httpd-2.4.2/server/mpm' make[4]: Entering directory `/home/ubuntu/matt/apache_foolings/httpd-2.4.2/server/mpm/event' make[4]: Leaving directory `/home/ubuntu/matt/apache_foolings/httpd-2.4.2/server/mpm/event' make[3]: Leaving directory `/home/ubuntu/matt/apache_foolings/httpd-2.4.2/server/mpm' make[2]: Leaving directory `/home/ubuntu/matt/apache_foolings/httpd-2.4.2/server' make[2]: Entering directory `/home/ubuntu/matt/apache_foolings/httpd-2.4.2/modules' make[3]: Entering directory `/home/ubuntu/matt/apache_foolings/httpd-2.4.2/modules/aaa' Building shared: mod_authn_file.la mod_authn_dbm.la mod_authn_anon.la mod_authn_dbd.la mod_authn_socache.la mod_authn_core.la mod_authz_host.la mod_authz_groupfile.la mod_authz_user.la mod_authz_dbm.la mod_authz_owner.la mod_authz_dbd.la mod_authz_core.la mod_authnz_ldap.la mod_access_compat.la mod_auth_basic.la mod_auth_form.la mod_auth_digest.la mod_allowmethods.la make[4]: Entering directory `/home/ubuntu/matt/apache_foolings/httpd-2.4.2/modules/aaa' /usr/share/apr-1.0/build/libtool --silent --mode=compile x86_64-linux-gnu-gcc -std=gnu99 -pthread -DLINUX=2 -D_REENTRANT -D_GNU_SOURCE -I. -I/home/ubuntu/matt/apache_foolings/httpd-2.4.2/os/unix -I/home/ubuntu/matt/apache_foolings/httpd-2.4.2/include -I/usr/include/apr-1.0 -I/home/ubuntu/matt/apache_foolings/httpd-2.4.2/modules/aaa -I/home/ubuntu/matt/apache_foolings/httpd-2.4.2/modules/cache -I/home/ubuntu/matt/apache_foolings/httpd-2.4.2/modules/core -I/home/ubuntu/matt/apache_foolings/httpd-2.4.2/modules/database -I/home/ubuntu/matt/apache_foolings/httpd-2.4.2/modules/filters -I/home/ubuntu/matt/apache_foolings/httpd-2.4.2/modules/ldap -I/home/ubuntu/matt/apache_foolings/httpd-2.4.2/modules/loggers -I/home/ubuntu/matt/apache_foolings/httpd-2.4.2/modules/lua -I/home/ubuntu/matt/apache_foolings/httpd-2.4.2/modules/proxy -I/home/ubuntu/matt/apache_foolings/httpd-2.4.2/modules/session -I/home/ubuntu/matt/apache_foolings/httpd-2.4.2/modules/ssl -I/home/ubuntu/matt/apache_foolings/httpd-2.4.2/modules/test -I/home/ubuntu/matt/apache_foolings/httpd-2.4.2/server -I/home/ubuntu/matt/apache_foolings/httpd-2.4.2/modules/arch/unix -I/home/ubuntu/matt/apache_foolings/httpd-2.4.2/modules/dav/main -I/home/ubuntu/matt/apache_foolings/httpd-2.4.2/modules/generators -I/home/ubuntu/matt/apache_foolings/httpd-2.4.2/modules/mappers -prefer-pic -c mod_authn_file.c && touch mod_authn_file.slo /usr/share/apr-1.0/build/libtool --silent --mode=link x86_64-linux-gnu-gcc -std=gnu99 -pthread -o mod_authn_file.la -rpath NONE/libexec -module -avoid-version mod_authn_file.lo libtool: link: only absolute run-paths are allowed make[4]: *** [mod_authn_file.la] Error 1 make[4]: Leaving directory `/home/ubuntu/matt/apache_foolings/httpd-2.4.2/modules/aaa' make[3]: *** [shared-build-recursive] Error 1 make[3]: Leaving directory `/home/ubuntu/matt/apache_foolings/httpd-2.4.2/modules/aaa' make[2]: *** [shared-build-recursive] Error 1 make[2]: Leaving directory `/home/ubuntu/matt/apache_foolings/httpd-2.4.2/modules' make[1]: *** [shared-build-recursive] Error 1 make[1]: Leaving directory `/home/ubuntu/matt/apache_foolings/httpd-2.4.2' make: *** [all-recursive] Error 1 Thanks!
