David, just tried to refresh my build after an update and have run into a problem with GRP_LIST. A "make check" in grp now says: ./.libs/libgrp.so: undefined reference to `grp_list_' a quick scan reveals this makes sense as the test target links against the standalone version of GRP, but GRP_LIST is an ADAM routine, which has sneaked in via a recent update to grp.c. Must be time to introduce a grp_adam.c file. Cheers, Peter. -- Peter W. Draper, http://astro.dur.ac.uk/~pdraper
