[Paraview] Question about build paraview

[Moreland, Kenneth]

Actually I find the easiest way to do it is, assuming you have icc in your path, to set the CC and CXX environment variables on the command of the first run of cmake (or ccmake or cmake-gui, whichever one you are using). So the start of your build would be something like this:

mkdir paraview-build
cd paraview-build
CC=icc CXX=icc cmake ../paraview

That should ignore gcc. (Remember, you have to delete all of any build files you have created so far and start over. Once CMake picks a compiler, you cannot change it without starting over.)

It's kind of a quirk of CMake, but once CMAKE_CXX_COMPILER is set by the initial CMake configuration, you can't change it. So what should you do?

The solution is to set an environment variable named CMAKE_CXX_COMPILER in your shell prior to running CMake for the first time. Set that variable to the path of version of gcc or icc you want to use, and that should do it. You may also need to set CMAKE_C_COMPILER as well.

HTH,
Cory
