Building and Installing

The project can be built by running:

mkdir build && cd build
cmake ..
make

and installed to /usr/ by running:

mkdir build && cd build
cmake -DCMAKE_BUILD_TYPE=Release ..
make install

Common Install Problems:

• Configuration files are not able to be saved!
  • If you installed using sudo make install, run:

sudo chown $USER:$USER -R ~/.QtLean

• Python libraries cannot be found!
  • See the section "Python Config Errors". Otherwise...
  • Try installing using a Python 3.6 Conda environment.
  • Try installing Python 3.6 independently of Conda (that is, using your package manager or from https://www.python.org/downloads/release/python-368/).

Python Config Errors

If your Python is unable to be configured via CMake, run the following in your Lean root directory and then modify the generated PythonConfig.h file in your build directory with the result: py_configure.sh

Usage

Note, it is best to run QtLean from the console. Such must be done in order to see console output!

From your build directory, clone Lean (git clone http://github.com/QuantConnect/Lean), cd into the Lean subdirectory and execute

../QtLean

If QtLean is installed, it can be called from any Lean directory by executing:

QtLean
