Not sure if it's enough information, my python version prints Python 3.13.9

[DavidSpickett]

I don't think this is specific to lldb-dap, it just happens to build the SBAPI files on the way there.

The file with the error is generated by SWIG, what version of that do you have installed? We require 4 or later (https://lldb.llvm.org/resources/build.html#preliminaries), but I would hope that if you had < 4, we would have errored during cmake configuration.

Are you building with a recent version of llvm-project, or is it a release of llvm?

@JDevlieghere has been in this area a lot and will be more familiar with it.

[tuliom]

We're also seeing this on Fedora Rawhide, which has SWIG 4.4.0.
Interestingly, this doesn't happen on Fedora 42 or 43. They both have SWIG 4.3.1.

We were running our daily snapshots using commit 5305a53
We didn't see this issue when we used this commit.

[tuliom]

By the way, we have a full log available at: https://download.copr.fedorainfracloud.org/results/@fedora-llvm-team/llvm-snapshots-big-merge-20251115/fedora-rawhide-x86_64/09800044-llvm/builder-live.log.gz

[tuliom]

I wonder if this is actually a bug in SWIG: swig/swig#3283

[JDevlieghere]

I believe 26.04 is still under development, right?

Knowing your SWIG version would be helpful (preferably from the CMake configuration output to make sure we're looking at the one used by the build, rather than the one that happens to be first in your PATH). We have bots building against Python 3.13 so I don't expect that to be an issue.

[Zorgatone]

Hey sorry I will check again next week when I'll be on a windows machine again!

Yes Ubuntu 26.04 is under development. I was using a release version of llvm to build llvm-project, I don't remember the version of release llvm that was installed, and I will check the SWIG version too.

And during cmake configuration I didn't get any error, only on build. I was trying to get a built lldb-dap executable for that system, because the prebuilt one was linked to the wrong dynamic libraries (different versions not found on my system), and that's why I tried building from source

[Zorgatone]

I also get the same build error on a Ubuntu 26.04 (aarch64) Orbstack machine on macOS (so not tied to Windows 10 WSL2 Ubuntu 26.04 x86_64):

I didn't get any configuration errors with cmake either.

I'll try checking which SWIG version I have

Knowing your SWIG version would be helpful (preferably from the CMake configuration output to make sure we're looking at the one used by the build, rather than the one that happens to be first in your PATH). We have bots building against Python 3.13 so I don't expect that to be an issue.

$> swig -version

SWIG Version 4.4.0

Compiled with g++ [aarch64-unknown-linux-gnu]

Configured options: +pcre

Please see https://www.swig.org for reporting bugs and further information

$> python3 --version
Python 3.13.9
