Cross-compiling Rust for Pinephone
07-16-2020, 01:22 PM
I successfully cross-compiled the examples 
The way I did it was less than optimal though I think. I read through the errors listed when trying to compile them and searched for those libraries on https://archlinuxarm.org/packages. All the packages I needed were available there so I downloaded each package and extracted them. Some had the extension .tar-1 or something similar after unpacking. I renamed them to .tar and unpacked them again. They all had a folder called usr. I copied the folder /usr/aarch64-linux-gnu to make sure I can revert the changes in case I break something and then copied the content of the usr folder of all the downloaded packages into the folder /usr/aarch64-linux-gnu. Then I tried compiling again. Now different libraries were missing (the dependencies of the newly added libraries) and I repeated the whole process for those missing libraries until none were missing and I successfully compiled the examples.
Its not a very elegant solution and involved a lot of copy and pasting so now I will look into how to add the necessary packages to the AUR so others can get those libraries easier
