Building for Linux

Version Requirements

Following are the minimum required versions for the tools and libraries you need for building Pie Noon for Linux:

• OpenGL: libglapi-mesa 8.0.4 (tested with libglapi-mesa 8.0.4-0ubuntu0)
• GLU: libglu1-mesa-dev 8.0.4 (tested with libglu1-mesa-dev 8.0.4.0ubuntu0)
• cmake: 2.8.12 or newer
• automake: 1.141 or newer
• autoconf: 2.69 or newer
• libtool: 2.4.2 or newer
• Python: 2.7.*
• cwebp: 0.4.0 or newer (available from the WebP Precompiled Utilities page)
• Ragel: 6.9 or newer

Before Building

Prior to building, install the following components using the Linux distribution's package manager:

• cmake. You can also manually install from cmake.org.
• OpenGL (libglapi-mesa).
• GLU (libglu1-mesa-dev).
• autoconf, automake, and libtool
• Python: 2.7.*
• cwebp: 0.4.0 or newer
• Ragel: 6.9 or newer

For example, on Ubuntu:

sudo apt-get install cmake
sudo apt-get install libglapi-mesa
sudo apt-get install libglu1-mesa-dev
sudo apt-get install autoconf automake libtool
sudo apt-get install python
sudo apt-get install webp
sudo apt-get install ragel

Building

• Generate makefiles from the cmake project in the pie_noon directory.
• Execute make to build the game.

For example:

cd pie_noon
cmake -G'Unix Makefiles'
make

To perform a debug build:

cd pie_noon
cmake -G'Unix Makefiles' -DCMAKE_BUILD_TYPE=Debug
make

Build targets can be configured using options exposed in pie_noon/CMakeLists.txt by using cmake's -D option. Build configuration set using the -D option is sticky across subsequent builds.

For example, if a build is performed using:

cmake -G"Unix Makefiles" -DCMAKE_BUILD_TYPE=Debug
make

to switch to a release build CMAKE_BUILD_TYPE must be explicitly specified:

cmake -G"Unix Makefiles" -DCMAKE_BUILD_TYPE=Release
make

Executing the game.

After building the project, you can execute the game from the command line. For example:

./bin/pie_noon
