Hi, Thank you for your efforts. --8<---------------cut here---------------start------------->8--- The latest revision of this patch series rebases the changes against the latest Guix master. Further, upon trying to build the package, I noticed that an update recently made to the go-golang-org-x-net package causes an error on go-mau-fi-whatsmeow's build, so I've decided to revert its commit, and I presume it's related to the package having an "embed:" directive (which gives issues when building Go packages in Guix). I'd highly appreciate it if you could help me further debug this issue or guide me on another course of action. --8<---------------cut here---------------end--------------->8--- Try not to downgrade packages and place an adjusted package with specific version to cover your chain of dependencies. To resolve recently introduced "embed" option I've got semi simple solution https://git.savannah.gnu.org/cgit/guix.git/commit/gnu/packages/golang-build.scm?h=go-team&id=cf990a27810ce1938933d6e5edb7b6d1c5f1bf94 --8<---------------cut here---------------start------------->8--- + (add-after 'unpack 'fix-embed-files + (lambda _ + (for-each (lambda (file) + (let ((file-store-path (readlink file))) + (delete-file file) + (copy-recursively file-store-path file))) + (find-files "src" ".*(editions_defaults.binpb)$")))) --8<---------------cut here---------------end--------------->8--- Logic is - remove symlink and copy required file into build directory path which helps golang to happy. I'm not quite sure what did you try to archive in patches like "[PATCH v2 54/71] gnu: Add go-mau-fi-libsignal-state-store." Please feel free to submit v3 if you are still interested in this patch series. -- Oleg
