The following values are permitted: - - internal: Use Open MPI's internal copy of libltdl. - external: Use an external libltdl installation (rely on default - compiler and linker paths to find it) - : Same as "internal". - : Specify the location of a specific libltdl - installation to use - - By default (or if --with-libltdl is specified with no VALUE), Open - MPI will build and use the copy of libltdl that it has in its source - tree. However, if the VALUE is "external", Open MPI will look for - the relevant libltdl header file and library in default compiler / - linker locations. Or, VALUE can be a directory tree where the - libltdl header file and library can be found. This option allows - operating systems to include Open MPI and use their default libltdl - installation instead of Open MPI's bundled libltdl. +--with-libltdl= + Specify the directory where the GNU Libtool libltdl libraries and + header files are located. This option is generally only necessary + if the libltdl headers and libraries are not in default + compiler/linker search paths. Note that this option is ignored if --disable-dlopen is specified.
