================================================================================
    : Required packages
================================================================================
    gcc-c++ (use other compilers at your own risk)
    OpenMP devel library (libgomp or the omp that comes with your compiler)
Optional packages for Graphics display
    glew devel 1.5 or higher
    freeglut devel 2.6.0  or higher
    Working OpenGL/GLU headers and libraries (you most definitely have these)

================================================================================
    : NOTES
================================================================================

1) llvm/clang  status:
clang++ is not yet mature enough to compile electromag without errors.
If you still wish to give it a try, change the CMAKE_C_COMPILER to clang, and
CMAKE_CXX_COMPILER to clang++.

2) Older versions of gcc
I have recieved several reports of compilation issues with gcc 4.1.2.
gcc 4.4.4 and later should work fine. Earlier versions have known issues about
some exotic c++ tricks which electromag uses.

3) Earlier versions of CMake
Some distributions package old versions of cmake. You may edit
CMakeLists.txt to select a lower cmake_minimum_required,
but your your milage may vary. The best option is to upgrade your cmake.

================================================================================
    : Compiling
================================================================================

0) cd to trunk directory
1) $ mkdir build
2) $ cd build
3) $ cmake ..
4) Optional: select Release build using ccmake ..
5) $ make

electromag-with-cuda's Issues

Compilation with GCC yields Undefined reference to constructor of template class CudaElectrosFunctor

What steps will reproduce the problem?
1. Compile ElectroMag with GCC

What is the expected output? What do you see instead?
Expected to compile and link.
Compiles, but linking generates the following error
In Electrostatics.coo: undefined reference to 
CudaElectrosFunctor<float>::CudaElectrosFunctor();
