Tim,

Thanks for pointing this out (and thanks also to Shiqing and Damien under separate cover). I created a new project which uses the WIN64 preprocessor flag and the changed the machinetype from x86 to x64 in the linker and my app compiles/links and runs successfully.

Thanks Again,

Alan

During compilation I get warning messages such as :

cmsolver.cpp

Which indicates that the openmpi version “openmpi_v1.6-x64” is 64 bit. And I’m sure that I installed the 64 bit version. I am compiling on a 64 bit version of Windows 7.

setting X64 compiler project options?
