meson build fails

[Tetsujinfr]

hi, not sure what I did wrong. I installed all the dependencies, then I am doing the following (I am on a Jetson with Jetpack 4.4, with ARM64 CPUs):

tetsfr@tets:/media/tetsfr/SSD$ git clone --recurse-submodules  https://github.com/meghprkh/libgamepad.git

Hi, it seems that the vala compilation for meson has changed

https://mesonbuild.com/Vala.html#building-libraries

We need to build all three, a header, a GIR and a VAPI. I don't have access to a setup right now, but this shall be an easy change, let me know if you need help

More detailed steps afaik:

• Remove vala_args in src/meson.build
• For additional VAPI search path of /drivers/linux/vapis, use add_project_arguments as mentioned here
• Get rid of the manual installs and use install_dir: [true, true, true, true]) as mentioned here

[Tetsujinfr]

yes I would need more details on the steps to follow. I am not familiar with Meson, neither with Vala I am afraid. I do not know which path to add to the search with add_project_arguments and I do know how to use install_dir and where. I am quite confused on how to get it to compile properly.
thanks a lot for your help
