I am trying to package lix for openSUSE. I have all of the dependencies and got the build to start (with the workaround from #470).

However, the build fails:

I tried to translate the just build commands to meson to have one layer of abstraction less. That should not be the problem.

I think I need to set the $mesonFlags to set enable-docs to true, if I understand the part in the packages.nix file correctly.

Line 207 in 278fddc
(lib.mesonBool "enable-docs" canRunInstalled)

Maybe the README could be expanded to contain a safe set of $mesonFlags for builds on non-NixOS machines?

Kind Regards,
Johannes

this is poor documentation, but what you're actually experiencing here is that we punted on the issue of compiling lix-doc/ with meson for the sake of time. this will be fixed in the in-development 2.92 release by building it with meson instead.

the piece of packaging that you're missing is lix-doc/package.nix, which just builds lix-doc as a rust staticlib. this is then put in the linker search path by nix magic in our case, but you probably have to jam in LDFLAGS in your case.

this is not related to enable-docs, actually. lix-doc is part of nix repl, and it's kind of an evil little trap that we carelessly set to have it not be declared as a meson dependency anywhere so it randomly fails to link if you've not injected it into the link search path.

i would not make it a separate package for opensuse, it is an implementation detail of lix that just is built as a separate package in our case because of technical limitations in nix plus it having been the most expedient thing to do at the time, when we weren't meson-only.

the actual thing enable-docs is saying that you're reading is "enable the documentation if the building system can run the host-platform code" i.e. it's not cross compilation. this is because of settings default values/docs and a bunch of other stuff that is extracted from the nix binary and put into the manual. we consider this technical debt that will be eliminated given sufficient time.

Thanks for the fast reply. Is there any flag I can set to skip the lix-doc part when building with meson?

Thanks for the detailed explanation. If I understand you correctly I would first compile the nix-docs, before I compile lix. All within the same openSUSE package and from the same git repository?

If this is work in the making, then I will wait for 2.92 to be released and try again then.

Have a nice day!

Thanks for the fast reply. Is there any flag I can set to skip the lix-doc part when building with meson?

No. It is a required part of the program that is necessary for proper repl functionality. You have to cargo build it outside of meson, currently, then provide it somewhere in the linking search path so the linking command you saw fail above will work.

OK, I'll try that and report back. Thanks, @jade
