@tfl5034 - yeah, that was my conclusion as well, see also my rejected PR here (which also sets a few more -X... flags): https://github.com/AdaCore/ada_language_server/pull/470

Thanks for the help! Figured the issue out: I had to explicitly set the make variable LIBRARY_TYPE=relocatable to build and then I had to patch the Makefile to add a variable to a gprbuild command. https://aur.archlinux.org/packages/ada_language_server/

Hello,

There’s a known bug somewhere between GCC and GPRbuild: one one hand some Linux distros (ArchLinux and Ubuntu at least) configure GCC to automatically pass -pie when linking, and on the other hand, for GPRbuild passes the -r option to do a partial link when building standalone libraries in static mode (and Libadalang is a a standalone library).

Since -r and -pie are mutually incompatible, building Libadalang in static mode does not work on such distros. This is what I have documented in the libadalang-git package, and very likely why this package does not build LAL in static mode.

Now, if I understand correctly, ArchLinux packages should contain dynamically linked programs (to save disk space, avoid rebuilds on dependency update, …). So shouldn’t ada_language_server be built in dynamic mode, working around this static link issue?

If that helps, I’m also available on IRC (pmderodat@freenode, on #ada) :-)

@tfl5034: ah, I get it now! That's a weird one. Most of the Ada packages are built in three versions - static, static-pic and relocatable. Picking out xmlada_dom as a random example, the xmlada PKGBUILD builds both a usr/lib/xmlada/xmlada_dom.static/libxmlada_dom.a (static) as well as a usr/lib/xmlada/xmlada_dom.relocatable/libxmlada_dom.so (relocatable), so I'm really not sure what it's complaining about there.

One thing I noticed in that log is that it's building with -XBUILD_MODE=dev, might want to use make BUILD_MODE=prod.

I'd gladly assist with bug hunting (I have some experience now after updating all the AdaCore packages to 2020...), just poke me on IRC (lambda@freenode) if you want.

@xiretza I wanted to clarify that this is not necessarily an issue building your libadalang package. It builds and installs fine. What I want to do is leverage this package to build ada_language_server version 21.0.11. I am creating a PKGBUILD for ada_language_server and it fails on the build step when executing make. The error is as follows:

@tfl5034: please post the error you get when building the actual package, without messing around in the sources yourself. FWIW it builds fine in a clean chroot here.

I'm getting an error when using this package to compile ada_language_server. The error is that libadalang is compiled as a shared project while seemingly every other dependency of ada_language_server is static. I tried adding --library-type static to all the ada/manage.py commands, but got the following linking error. Got any idea on a fix?

Thank you very much for the quick answer, I would like to wait a few days to update the gnatcoll-iconv package, so far I can use eg VSCode with ADA extension.

@krouziciorel: as the error says, files from gnatcoll-iconv and libadalang were compiled with different GNAT/compiler versions - you probably have to rebuild gnatcoll-iconv. You can either do that manually right now or wait a few days for a TU to accept the open merge request into gnatcoll-bindings, at which point I'll bump the pkgrel and your AUR helper will presumably update it anyway.
