When the development version of Autoconf is used to generate a configure script from CVS libltdl's configure.in this error occurs. configure.in:36: error: m4_require: circular dependency of AC_LTDL_SYMBOL_USCORE configure.in:36: AC_LTDL_SYMBOL_USCORE is required by... ./aclocal.m4:3382: AC_LTDL_DLSYM_USCORE is expanded from... ./aclocal.m4:3318: AC_LTDL_SYMBOL_USCORE is expanded from... configure.in:36: AC_LTDL_SYMBOL_USCORE is required by... ./aclocal.m4:3142: AC_LIB_LTDL is expanded from... configure.in:36: the top level The end result is that an empty configure script is generated. These actions should be taken: o Libltdl's configure.in should be fixed so that it is compatible with both released and development Autoconf. o Autoconf should either preserve an existing configure script, or should leave no configure script at all after an error. Empty configure scripts have a nasty habit of accidentally getting into distributions.
