using dpkg-deb in a Guix package definition

using dpkg-deb in a Guix package definition

[Benjamin Slade]

Hello Guix,

I've been using this package [ <https://github.com/NixOS/nixpkgs/blob/nixos-unstable/pkgs/applications/networking/browsers/brave/default.nix#L177> ] from Nix on top of Guix System, but I'd like to create my own Guix package for it instead. Are there any good examples of writing a Guix package definition using dpkg?

best,
 —Ben

I do not know what is «this package». :-)

Well, if by using ’dpkg’ you mean reuse the binary inside a .deb
archive, then no, not good examples.  Guix tries hard to build from
source.

For your curiosity, you could give a look at the ’copy-build-system’;
maybe that could fit your needs.


Cheers,
simon

I'm not sure if this helps, but I had to consume a deb and wrote a package that
unpacks it to get the binary:

Thanks!  I got a partial definition done; it at least downloads and dpkg's, though I have to figure out what to patchelf still (and would rather have in /bin than /opt).
