Good afternoon.
I’m trying to build an apk from its source code on github. The application is SimpleX from this repository. I talked to the developers and they told me I had to use Nix. I don’t know much about Nix, but I saw that in the project there is a flake.nix script. From this folder run the nix build command however after a minute an error message appeared:
error: flake <PATH> does not provide attribute 'packages.x86_64-linux.default' or 'defaultPackage.x86_64-linux'
I don’t know what I should do to solve the problem. Thank you
I put the beginning of the flake.nix script. I don’t put it in full because of the character limit, but it is in this link.
