Open MPI is now set up to use either of Solaris's two versions of STL. The problem is that if libtool links in libCrun/libCstd, then bad things happen if the user code contains code for the other STL version. (Not sure if I got that 100% right.) Dan overhauled Open MPI's handling of STL a while ago (r17448, r17418, r17409, ...). -Ethan > > george. > > On Nov 19, 2008, at 09:11 , Ethan Mallove wrote: > >> ---------------------------------------------------------------------------- >> WHAT: Add patch-libtool-for-sun-studio.pl script >> >> ---------------------------------------------------------------------------- >> WHY: >> >> There are a couple issues with SunStudio and Libtool: >> >> 1.
