I would suggest build a 64-bit libxml2 instead of using ‘-m64’ for MPICH. — Huiwei On Jun 25, 2014, at 1:26 AM, Siegmar Gross <[email protected]> wrote:

Solaris uses LD_LIBRARY_PATH for 32-bit libraries/executables and LD_LIBRARY_PATH_64 for 64-bit ones. When I build "mpich" as 64-bit version, the 32-bit library for "libxml2.so" will be used without rpath. I don't know if that is a problem of our gcc-installation or your Makefile, but I could solve the problem with rpath.
