In trying to resolve a C++ issue within Open MPI we've run into an issue
with Libtool automatically linking in Cstd.
Because Sun Studio supports two different types of C++ STL libraries
(Cstl and stlport4) we needed to remove Open MPI's reliance on STL
functions so applications being compiled with Sun Studio could use
either version of STL libraries (note once you link with one you cannot
use the other STL library).
After making Open MPI STL agnostic we found out that libtool is
automatically adding in "-lCstd -lCrun" to CXXFLAGS which is causing our
fix to make Open MPI STL agnostic useless. We currently are hacking
aclocal's LT macros to *not* add the Cstd library to any of OMPI's
CXXFLAGS to work around this issue.
We are wondering if there is a way libtool could remove the addition of
-lCstd and -lCrun to CXXFLAGS when it detects Sun Studio Compilers being
used?
