error: the runtime load version 17 is not compatible with this compiler 16

Trying to compile MulleObjC with mulle-clang 10.0.0 results in that error.

Command line:

It's basically as the error says, the compiler is too old. It shows runtime-load-version: 16 but 17 is required. So you need to upgrade the compiler. The runtime internal structs sometimes change and a matching compiler is required to produce these structs (like Classes or Methods)

[bugravirgomercury]

Oh, I understand it now. I needed to double-check it as I just used the install-mulle-clang script to build mulle-clang recently. Guess the version numbers need to be updated there. Thanks for your help nonetheless 👍

[mulle-nat]

Hmm, no. The version numbers should be consistent already in the projects. You need the proper projects, otherwise things go bad in very subtle ways. What might trip you up, as it did me on occasions, is, that the mulle-clang repository is no longer used and the compiler has to be built with the mulle-clang-project repository. That's because llvm changed to a mono-repo and I had to follow suite. Otherwise it would have become even more tedious, as it is already, to keep the mainline and the mulle-objc branch in sync.

[bugravirgomercury]

Yeah, I missed the "superseded" notification at mulle-clang repository, guess I have to compile mulle-clang-project repository, which makes my computer unusable for a couple of hours. But I will take advantage of LTO+PGO this time. Maybe I can compile mulle-objc-runtime + MulleObjC with LTO maybe, for extra optimization. Thankfully, patience is one of my virtues.

[mulle-nat]

I know the pain :) As I see CMAKE_SYSTEM_NAME is Linux you could take one of the prefabricated builds for Debian/Ubuntu. I think a dpkg is just a tar or cpio archive that unpacks into /opt (in the mulle-clang case) and adds some symlinks. That's maybe good enough for other linuxes as well, not sure though.

[bugravirgomercury]

I actually tried the prefab builds first, but my distro needs to be updated (for glibc etc), and the updates haven't delivered yet, as new version of glibc is still being tested by distro manager. I'm using deepin btw :D So I build it from source, (and sleep on it).

[mulle-nat]

If one could link glibc statically that would be a win :)

[bugravirgomercury]

Yeah, definitely!

[mulle-nat]

Is it working now for you ? Should I close this ?
