Thanks for reaching out. How are you starting cuda-gdb in this case? Are you trying to invoke /usr/local/cuda-12.5/bin/cuda-gdb-python3.12-tui directly?

Hi
i started the CUDA_GDB as follows : cuda-gdb --version

now i have installed the CUDA 12.5 Update 1 the same Error

Without a working CUDA-GDB debugger, the NVIDIA CUDA 12.5 toolkit is worthless and unusable

regards
Franz

the invoke of directly of cuda-gdb-python3.12.tui produce the same error

As a workaround, you can try explicitly starting:

/usr/local/cuda-12.5/bin/cuda-gdb-minimal

This variant lacks python and TUI integration. We will fix the decision logic in a future CUDA release. When fixed, the workaround will no longer be necessary.

@fbernasek535 can you also provide us with the output from:

ldd /usr/local/cuda-12.5/bin/cuda-gdb-python3.12-tui
