Cmake Build Issues on Arch Based Linux.

[Zeludon]

Hey I followed the build instructions included in the readme, adapting the packages for what is available on Arch

This guide was used for the switch packages and they (switch-dev switch-bzip2 switch-freetype switch-glad switch-glm switch-libdrm_nouveau switch-libpng switch-mesa switch-pkg-config switch-sdl2 switch-zlib ) all installed successfully.

The linux build packages libsdl2-dev libfreetype6-dev libglm-dev were replaced by their pacman equivalents, sdl2 freetype2 glm as arch does not use separate dev packages.

Unfortunately, attempting to build with DBUILD_LINUX=1 results in the following

make texture.elf  
Scanning dependencies of target texture.data
[  0%] Built target texture.data

make[1]: *** [CMakeFiles/Makefile2:322: examples/texture/CMakeFiles/texture.elf.dir/rule] Error 2
make: *** [Makefile:183: texture.elf] Error 2

Similarly building the switch package with DBUILD_SWITCH=1 results in a different error

make texture.nro

It would be very much appreciated if I could be pointed in the right direction on how to fix this, aside from switching linux distributions, as that really shouldn't be necessary.

Hi,

for the switch error, are you sure you did install devkitpro to "/opt/devkitpro " and you did export the swtich sdk variables ( export DEVKITPRO=/opt/devkitpro ) ?

Else, can you provide me the exact distribution and version you are using? I'm going to make a VM and take a closer look.

[Zeludon]

Yes I'm fairly sure.

I added these lines to my ~/.profile and they are accessible from my zsh instance.

export DEVKITPRO=/opt/devkitpro
export DEVKITARM=/opt/devkitpro/devkitARM
export DEVKITPPC=/opt/devkitpro/devkitPPC

As for my distribution it is Manjaro KDE 18.0. Available here https://manjaro.org/download/kde/

Thanks for your time as I'd enjoy trying this library out.
