XFLR5 for Ubuntu

This repo provides the latest XFLR5 (currently v6.47) patched for Ubuntu 18.04 LTS using Qt 5.13


1 First of all, start by installing the required dependencies:

sudo apt install build-essential mesa-common-dev mesa-utils libgl1-mesa-dev libglu1-mesa-dev

2 Next, head over to and download the Linux installer. Run it and make sure to install Qt 5.13.0 for GCC 64-bit. If you don't change the default options, it will be installed in ~/Qt/5.13.0.

3 Download the files from this repo and extract them:

cd /path/to/repo
git clone

4 Move the main xflr5 folder to your preferred install location:

cd /path/to/repo
sudo mv xflr5/ /opt/

5 Follow the standard install procedure:

cd /opt/xflr5/
make # will take a while
sudo make install # create executable
sudo ldconfig # make the new shared libraries available

At this point, you should be all ready to go. You can check by running XFLR5 from the command line:


6 Finally, in order to run the software more easily, move the provided *.desktop file to your preferred location:

cd /path/to/repo
mv xflr5.desktop ~/.local/share/applications/

And now you should be able to launch XFLR5 from the Activities Overview.
