(autoconf-2.60 and 2.61 IIRC; I can't remember if it was fixed in 2.62 or not, but it is, in 2.63). > I suppose Autoconf could provide a macro to access this variable > which we could then document. That would be useful. I've used $ac_configure_args, filtered, to pass to a sub-configure in a hybrid build, (where the main application is cross-compiled, but the build process needs to create some tools, for its own use on the `build' platform; the sub-configure needs to be invoked with the --host spec filtered out, along with any reference to host_alias, and IIRC, I also filtered out similar references which relate to the --build spec; furthermore, the sub-configure cannot share a cache file, with the main configure process). A documented, and therefore hopefully stable, mechanism to achieve that objective would be much preferred, to a technique based on an undocumented feature, such as is currently required. -- Regards, Keith. _______________________________________________ Autoconf mailing list Autoconf@xxxxxxx http://lists.gnu.org/mailman/listinfo/autoconf
