An GNEIS facility modeling library based on Geant4 toolkit.

• GCC 4.9.2 or higher
• CMake 3.1 or higher
• Geant4 10.4 or higher
• Google Test 1.7 or higher

• gneis-geant4 - library itself.
• basic - a very basic executable that invokes library.
• examples - macro files with GNEIS-related examples.

• Geant4 installed and configured

1. Go to your working directory, for example ~/workspace (all directory names are arbitrary).

2. Create gneis-geant4 subdirectory within the working directory.

3. Download content of gneis-geant4 repository into ~/workspace/gneis-geant4.

4. Create gneis-geant4-build subdirectory within the working directory.

5. Enter ~/workspace/gneis-geant4-build directory.

6. Run cmake:

cmake ~/workspace/gneis-geant4

6.1. If you need to install the library into your profile-specific directory rather than system directory, then set CMAKE_INSTALL_PREFIX system property for cmake as follows:

cmake -DCMAKE_INSTALL_PREFIX=~ ~/workspace/gneis-geant4

7. Build and install library and executables:

make && make install

8. Run example

cd ~/workspace/gneis-geant4
