Build error: #include "faust/dsp/libfaust.h"

[Bubobubobubobubo]

Hi! I ended up with a compilation error that you might want to investigate. I am using macOS Big Sur version 11.5.2. The system is up to date, to the best of my knowledge:

• supercollider and faustgen sources are stored in my root directory.
• the first step worked as intended. The error is encountered when running cmake --build . --config Release from the build directory.

I do not use Cmake very often. It might be something trivial that I overlooked.

Hmm. Interesting. It can't find the Faust source. Did you run the submodule update command as described in the readme ?

git submodule update --init --recursive

This should download a folder called Faust within the project. Get Outlook for Android

I runned git submodule update --init --recursive. The faust folder is here but does not contain any dsp folder.

There is a faustgen.h inside the faust/compiler/generator folder.

Ah then it has something to do with where Faust is installed on your system. Did you install Faust before running this ? I might have to tweak cmakelists to better pick this up on macos

[Bubobubobubobubo]

Faust is installed on my system, version 2.28.8. The command which faust returns /usr/local/bin/faust but isn't the build process using the freshly cloned submodule?

I'll try to uninstall Faust to see if it changes something.

Yeah you're right. As far as I can see, the CMake setup as it is now should pick this up if the submodule has been downloaded correctly. Hmm.

@madskjeldgaard : tried again this morning but stumbled upon the same error as two years ago.

Thanks. I'm not working on this anymore or at the moment at least, but I think this might be solved by having CMake manage Faust as a dependency using CPM, sort of how PortedPlugins does it https://github.com/madskjeldgaard/portedplugins/blob/main/CMakeLists.txt
