Only older GLIBCXX versions available on system

Hi, I am currently trying to use Bear with Vitis. In Vitis I use the custom command bear --output <output_path> -- make.
When running, I get these errors:

bear: /opt/Xilinx/Vitis/2022.2/lib/lnx64.o/Ubuntu/libstdc++.so.6: version `GLIBCXX_3.4.29' not found (required by bear)
bear: /opt/Xilinx/Vitis/2022.2/lib/lnx64.o/Ubuntu/libstdc++.so.6: version `GLIBCXX_3.4.26' not found (required by bear)
bear: /opt/Xilinx/Vitis/2022.2/lib/lnx64.o/Ubuntu/libstdc++.so.6: version `GLIBCXX_3.4.29' not found (required by /lib/x86_64-linux-gnu/libspdlog.so.1)
bear: /opt/Xilinx/Vitis/2022.2/lib/lnx64.o/Ubuntu/libstdc++.so.6: version `GLIBCXX_3.4.29' not found (required by /lib/x86_64-linux-gnu/libfmt.so.8)

We are using Vitis 2022.2 and Ubuntu 22.04 so the Bear version is 3.0.18.
We only have GLIBCXX up to 3.4.25 and I cannot really change our build environment.

Can someone tell me, which older Version of Bear I could use or if you have any other idea for a workaround?

We have similar issues in the past: #255, #556, #472

This could be because there are multiple version of the compilers/libraries installed. It looks like your case go with that too. Bear was compiled with the system libstdc++ (probably located in /lib/x86_64-linux-gnu), but when it is loaded it picks up the one from /opt/Xilinx/Vitis/2022.2/lib.

Hi, thanks for the answer. Since I could not change the gcc version used by Vitis I solved my issue by just building and installing Bear 4 manually on the system. Since it is written in Rust, it does not need the libstdc++ and therefore that solved the issue.
