Arch Linux User Repository

Thanks @ArchMcGee! I've gone ahead and updated the PKGBUILD so that it clones the submodules

EDIT: Fixed PKGBUILD at bottom.

The source does not compile using this AUR package or from the GitHub repo directly.

I have raised the issue at GitHub and received a reply to run the following command before config and build:

git submodule init && git submodule update

Running the above command fixes the issue although I do not know how to incorporate this into the PKGBUILD file to test it so thought I'd mention it here so the maintainer can maybe fix it.

Below is the error from the GitHub build although the error is the same when trying from the AUR.

And a few hints on getting this working...

Some hotkeys like F1 don't work, this has more info and the link mentions other hotkeys that do work:

https://github.com/projectM-visualizer/frontend-sdl2/issues/50#issuecomment-1679276936

Also, the user should make a config file (see https://github.com/projectM-visualizer/frontend-sdl2?tab=readme-ov-file#linux):

mkdir ~/.config/projectM
cp /usr/share/doc/projectm-sdl2-git/projectMSDL.properties ~/.config/projectM/

To get presets to load, replace ${application.dir} with /usr/share/projectM in the config file (~/.config/projectM/projectMSDL.properties).

There's currently an error building this:

CMake Error at /usr/lib/cmake/Poco/PocoConfig.cmake:29 (find_package):
  Found package configuration file:

    /usr/lib/cmake/Poco/PocoUtilConfig.cmake

  but it set PocoUtil_FOUND to FALSE so package "PocoUtil" is considered to
  be NOT FOUND.  Reason given by package:

  The following imported targets are referenced, but are missing: Poco::XML
  Poco::JSON

Call Stack (most recent call first):
  CMakeLists.txt:29 (find_package)

I found this patch which gets it to build:

https://gist.github.com/trinitronx/5f2d45e3f3f23e0ed905fff4d8a82f3e#file-poco-cmakelists-patch

Thanks for this package!
