Libcudadebugger.so is missing

Hi,

this is a follow-up of Can't use Cuda-gdb. I run into the same issue, but on Debian (testing). I also get

Could not find CUDA Debugger back-end. Please try upgrading/re-installing the GPU driver
[New Thread 0x7fff65a846c0 (LWP 58893)]

The CUDA driver has hit an internal error.

I use cuda-repo-debian11-12-0-local_12.0.0-525.60.13-1_amd64.deb downloaded from https://developer.nvidia.com/cuda-downloads?target_os=Linux&target_arch=x86_64&Distribution=Debian&target_version=11&target_type=deb_local.

Using CUDBG_USE_LEGACY_DEBUGGER=1 works as a workaround. I thought I report it, as I’d expect that the official downloads contain all the files that are needed.

Update: I forgot to mention that also apt-file search libcudadebugger.so doesn’t give any result.

Hi @volker.mische

I use cuda-repo-debian11-12-0-local_12.0.0-525.60.13-1_amd64.deb downloaded from CUDA Toolkit 12.3 Update 1 Downloads | NVIDIA Developer.

This link points to the CUDA Toolkit installation packages

libcudadebugger.so is a part of Nvidia GPU Driver package (e.g. Linux x64 (AMD64/EM64T) Display Driver | 525.60.11 | Linux 64-bit | NVIDIA )

E.g. for Arch Linux (Can't use Cuda-gdb) the distro GPU driver installer package re-packs the official Nvidia GPU driver package (https://github.com/archlinux/svntogit-packages/blob/packages/nvidia-utils/trunk/PKGBUILD ), so their installer has to be updated every time we add/remove files from the GPU Driver.

Assuming that Debian follows similar approach (rather then using the official Nvidia GPU driver package directly), the Debian packages would have to be updated as well.

Please note that I’m not using any packages from the official Debian distro repos. I’ve only installed Nvidias CUDA Toolkit from the link above. It contains those packages:

It contains the cuda-gdb package, so I would expect that it contains all files required to run cuda-gdb correctly.

Though I might missing the point here. Aren’t those Debian packages from the Nvidia website officially supported? Are they connected to the Debian project packaging effort?

And one more question: isn’t the Nvidia GPU Driver package included in the CUDA Toolkit installation package? I don’t seem to need to install any drivers after I’ve installed the CUDA Toolkit.

Please note that I’m not using any packages from the official Debian distro repos. I’ve only installed Nvidias CUDA Toolkit from the link above. It contains those packages:

Yes, but the libcudadebugger.so is a part of the Nvidia GPU Driver package (which is not part of CUDA toolkit)

Most likely the GPU Driver package was already installer as a part of base Debian installation (e.g. if you use any X applications).

I believe the package is called nvidia-driver:

Yes, it is called nvidia-driver.

$ apt-cache policy nvidia-driver
nvidia-driver:

As you can see, the installed version comes from the CUDA toolkit package and not from the distro packages. To me it looks like that the driver are part of the CUDA toolkit package. What am I missing?

Sorry, my bad. I re-checked the repo - you are right, libcuda.so is provided by the libcuda1 package.

There is also a libcudadebugger1 package (libcudadebugger1_525.60.13-1_amd64.deb), which contains the debugger library - could you try installing it?

7

That works! How could I’ve missed that. Thanks a lot.

May I propose to change the packaging, so that libcudadebugger1 is automatically installed if cuda-gdb is installed?

8

Sure, this is something we missed when creating the debugger library package - we will get it fixed.

Thank you for reporting this!!
