Cxx.jl seems not compatible with docker,about juliainterop/cxx.jl

This issue has nothing to do with Docker. I've been seeing the same thing with Ryzen 5900x (without Docker) and was just about to file a new issue. Cxx works fine with Ryzen 3900x so this seems somehow related to Ryzen 5000 series.

from cxx.jl.

A workaround might be passing target="..." to

Cxx.jl/src/initialization.jl

Line 430 in 896ec3c

C = setup_instance(GlobalPCHBuffer; PCHTime=PCHTime)

or directly create a correct llvm::Triple and put it here.

from cxx.jl.

@Gnimuc Thanks for answering my question :)

But I'm sorry I don't get it cuz I'm not aware of details.

I corrected the line you suggested as

C = setup_instance(GlobalPCHBuffer; PCHTime=PCHTime, target="...")

and it gives me

And I've tried "generic", "-triple", etc. .

Could you explane what I should do in detail?

from cxx.jl.

Gnimuc commented on June 11, 2024

I guess it should be something that matches ROS2's TARGET_TRIPLE.

from cxx.jl.

JinraeKim commented on June 11, 2024

I guess it should be something that matches ROS2's TARGET_TRIPLE.

I've changed it to target="aarch64-linux-gnu" and it produced a huge error message.
I think it's not correct because the ROS implementation (ROS.jl) is based on ROS(1), not ROS(2).
I tried to find a similar way, containing something like TARGET_TRIPLE for ROS(1), but I failed to search it :(
Thanks for helping me. If you have another idea for this issue, please tell me whenver you want :)

Notes

A huge error message (sorry but the beginning part is omitted due to space limit of my terminal)

I believe that's just an example. What's the cpu architecture type of the device that your docker instance is running on?

The docker container is run on Ryzen 5900x, and I guess that it's architecture is amd64.
The answer would be really poor due to the lack of my knowledge about cpu architectures.

Maybe the cpu architecture of Ryzen 5000 series is too new so that the old LLVM/Clang on which Cxx.jl based fails to make a correct detection.

This issue has nothing to do with Docker. I've been seeing the same thing with Ryzen 5900x (without Docker) and was just about to file a new issue. Cxx works fine with Ryzen 3900x so this seems somehow related to Ryzen 5000 series.

Oh, my cpu is also Ryzen 5000 series (5950x, probably?).
It might be an issue about cpu...!

Cxx.jl seems not compatible with docker about cxx.jl HOT 11 OPEN
