It would appear that altering the code into two AC_CONFIG_FILE statements worked. Thank you for the help. I'll up to the later version of m4 too.

AC_CONFIG_FILES expects literal file names, but the text "[AS_IF..." is not a literal filename. Meanwhile, it is safe to call AC_CONFIG_FILES more than once. AC_CONFIG_FILES([... list of unconditional makefiles]) AS_IF([test...], [AC_CONFIG_FILES([makefile1.am makefile2.am makefile3.am])]) > > I have verified that the list does not contain duplicate Makefile entries. The configuration script works fine when I remove the [AS_IF] statement, but not when it is included. I am fairly confident that the syntax used is correct and I have removed all trailing whitespace etc... Also, all of the Makefiles have been verified to be in UNIX format. > > I am using autoconf 2.68 and m4 1.4.15. Consider upgrading to m4 1.4.16; there was a nasty strstr() bug in m4 1.4.15 that has been proven to generate broken configure files in some cases. -- Eric Blake eblake@xxxxxxxxxx +1-801-349-2682 Libvirt virtualization library http://libvirt.org _______________________________________________ Autoconf mailing list Autoconf@xxxxxxx http://lists.gnu.org/mailman/listinfo/autoconf
