Is there some way to tell flatpak-builder
to cache the target
directory and run cargo build
only when there’s no cached target
? For big rust apps it may easily take more then 15 minutes to compile in debug mode, that makes everything very annoying to work with.
Try running flatpak-builder with --ccache
I tried that, and it seems like nothing changed. Maybe there’s something a have to configure, so it works with cargo? I didn’t find much about that option. Can you link/give more in-depth explanation of how it works and what to do?
This is for gcc / clang, not for Rust.
flatpak-builder doesn’t cache build artifacts. Only installation artifacts.
For C/C++, ccache works because it’s external and flatpak-builder does it’s thing with. There is no such thing with Rust or other languages.
