Getting started

(More in-depth guide here)

Downloading utopia

Clone the repository and its submodules

• git clone --recurse-submodules https://bitbucket.org/zulianp/utopia.git

or for older git versions

• git clone https://bitbucket.org/zulianp/utopia.git
• cd utopia
• git submodule update --init --recursive

Compiling utopia

Define the utopia path (you can also add it to your .bash_profile) export UTOPIA_DIR=

Go to the folder utopia/utopia:

• mkdir bin
• cd bin
• cmake .. -DCMAKE_INSTALL_PREFIX=$UTOPIA_DIR
• make
• make install.

For compiling the very experimental FE library follow the instructions HERE. In the future the Utopia FE library will be removed from this repository and will have its own repo (after a large scale refactoring).

MacOS Big Sur

For avoiding problems with cmake define the following env variable export SYSTEM_VERSION_COMPAT=1.
