Arch Linux Build Fails (CMAKE_MAKE_PROGRAM is not set. && /usr/bin/cc - broken)

[aemonge]

Describe the bug When trying to install the VPN with a arch linux (steam deck), i'm getting the following error after instlled the QT library:

❯ cmake --fresh -S . -B build -DCMAKE_PREFIX_PATH=~/opt/qt/6.6.0/gcc_64/lib/cmake
Configuring for Unix Makefiles
Setting build type Debug
CMake Error: CMake was unable to find a build program corresponding to "Unix Makefiles".  CMAKE_MAKE_PROGRAM is not set.  You probably need to select a different build tool.
CMake Error: CMAKE_C_COMPILER not set, after EnableLanguage
CMake Error: CMAKE_CXX_COMPILER not set, after EnableLanguage
-- Configuring incomplete, errors occurred!

which I've fixed with the following, but got another error

❯ cmake --fresh -S . -B build -DCMAKE_PREFIX_PATH=~/opt/qt/6.6.0/gcc_64/lib/cmake -DCMAKE_MAKE_PROGRAM=/home/deck/.conda/envs/vpn/bin/cmake

Hey @aemonge I think you have specified the value of CMAKE_MAKE_PROGRAM incorrectly here. The typical build flow for this software is that we use CMake to find build dependencies and generate makefiles, which then hands off the building of the software to a program like GNU Make. The error happening here is that you have provided CMake in place of GNU Make.

Normally, we would expect to find the make program in the $PATH environment variable, and the fact that it was not found points to a lack of build tools in the environment.

Furthermore, Arch Linux is not a currently supported Linux distribution, so I am afraid that you are also in uncharted territory here. I believe that the software should be buildable on Arch, but we don't have any experience or documentation on hand to draw from.

Hi @oskirby ,

Thanks a lot for the support. I know Arch is a bit different, but performance wise it excels (ask steam and the steam deck), so it would be great if mozilla can do more effort in this sense.

I'll keep this thread open for me, right now I need to update the packages; and that would take a bit more time for me to do so. As soon as a I find a solution, I'll post it here for anyone else looking for Arch support :)
