Hello all,

I'm trying to create a package definition, following mainly the manual pages :
- Packaging Guidelines
- Defining-Packages

- and Debugging-Build-Failures

In the attached .scm file, here is what I gathered it might look like as a first try.

The thing is that I can not debug the build process, even though I use the --keep-failed option : I'm not getting a temp build directory (/tmp/guix-build-...) as I expect :
arnaud@brix ~$ guix build -f /home/arnaud/freefilesync.scm --keep-failed
guix build: error: #<unspecified>: not something we can build
arnaud@brix ~$ cd /tmp/
babel-10188XJP/      guix-inst/           mozilla_arnaud0/    
emacs-guix-101889w1/ icecat_arnaud/       .overlayfs-workdir/ 
.esd-1000/           .ICE-unix/           .X11-unix/          
arnaud@brix ~$

One thing to add is that the downloaded source file is not tar.gz file format but zip file, perhaps that's part of the problem ?

This is a GuixSD install with guix pull done yesterday.

Thanks in advance

Arnaud
