Crusta Installation Instructions From Source Code


To checkout code:

To build:

For Mac OS X you will also need to install the XQuartz X server:

Quick Build and Install

Assuming you've also installed Vrui from source in some non-standard place:

git clone git://
cd crusta
PKG_CONFIG_PATH=/path/to/Vrui/pkgconfig cmake . -DCMAKE_INSTALL_PREFIX=/path/for/crusta
make install

(Vrui's pkgconfig directory should be somewhere beneath its lib directory.)

crusta commands will end up in /path/for/crusta/bin

Developer Build and Install

Follow these directions if you want to possibly mess around with the source code.

Checkout the source

The Crusta source code is available as a git repository on Github.

Please use the following to obtain a copy of the repository:

git clone git://

If you have write access on GitHub, you may clone this way:

git clone

Configure and build

Crusta uses cmake as the build management system. Please see the cmake webpage for detailed information about cmake. The build files are located in the 'build' subfolder of the source folder.

Assuming the source folder is ~/src/crusta, a typical release build would be setup as follows:

Step 1: Create a new folder for the specific build

cd ~/src/crusta
mkdir build
cd build

Step 2: Create a make file. Please note the trailing two dots as they are part of the command line.

cmake .. -DCMAKE_BUILD_TYPE=<Debug|Release> -DCMAKE_INSTALL_PREFIX=<crusta install path>

If you have installed Vrui in the default path and would like to install a release version of Crusta in your home folder (/home/username under linux and /Users/username under Mac OS; in the example these will be denoted with $HOME) the example cmake command is:

PKG_CONFIG_PATH=$HOME/Vrui-3.1/lib/x86_64-linux-gnu/pkgconfig cmake .. -DCMAKE_BUILD_TYPE=Release -DCMAKE_INSTALL_PREFIX=$HOME/crusta

(Vrui's pkgconfig directory may be somewhere else, depending on how your system is configured.)

(The Release build type is default, so you don't need to specify it if that is what you want.)

Step 3: Build and install

make install

Or for faster compilation on e.g. a dual-cored computer:

make -j2 install

The Crusta files should now be available at $HOME/crusta

Updating to the Latest Version

Once you have the git clone of the sources, fetching the latest updates is very quick and easy:

Step 1: Use the terminal to navigate to the Crusta folder. In our example:

cd ~/src/crusta

Step 2: Use git to fetch the latest source updates:

git pull

Step 3: Navigate to the release build folder and rebuild the executable:

cd build
make install

You now have bleeding-edge Crusta.
