Error when I run Projucer (segmentation fault (core dumped)) ubuntu WSL2

Hello everyone,

For the last 2 days ive been trying to get Projucer to work using WSL2 with Ubuntu.

What I have done so far:

  • Cloned the JUCE repo

  • Created a Develop branch and pulled the latest commits

  • Download the necessary dependencies

  • went to “JUCE/extras/Projucer/Builds/LinuxMakefile” and rant he linux command to compile the make file

  • ran command ‘./Projucer’

Error I received:

JUCE v6.0.8

What I have done so far:

I also ran ‘gdb Projcuer’ then ‘run’ and i get this error:

The last thing I tried was downloading the prebuilt windows Projucer from their website. This method allows me to open Projucer and create the project. However, I kept getting pathing issues which I fixed but then when I tried to build it I got hit with this error.

Ive only really messed around with JavaScript and Python to make full stack applications. So any help with this will be greatly appreciated because I really want to make music software. Thank you for all the help!

We don’t test the Projucer under WSL on Windows, and I’m not aware of any other users attempting to build under WSL - there’s a fair chance you’re the first person to attempt building with this particular setup!

On Windows, the best-supported toolchain is probably building with the Projucer’s Visual Studio exporter. I’d strongly recommend installing a copy of Visual Studio 2019 and using this for development, especially if you’re just starting out with C++.

We also support development on Windows using CMake, which supports a few more build tools (including Ninja and CodeBlocks), but this is a bit more involved to set up and I wouldn’t recommend it to a beginner.

Thanks for the speedy reply. You really saved me from bashing my head against the wall.

I am trying to do this tutorial using JUCE framework from freecodecamp (Learn Modern C++ by Building an Audio Plugin (w/ JUCE Framework) - Full Course - YouTube)

Will the first windows option with using Visual Studio 2019 have the necessary tools to build out this Simple EQ?

Thank you again for the help!

Yes, the Projucer and Visual Studio workflow I mentioned above should have everything you need to follow that tutorial.

Thank you for all the help. I cant wait to start using this framework!
