Linking Error: "fatbindata already defined" and LTO wrapper issue

Accelerated Computing CUDA CUDA Programming and Performance
1

Hello,

I’m encountering an issue during the linking phase of my CUDA project. All my CUDA files compile successfully, but I get the following error when linking:

  fatbindata already defined
  error with lto wrapper

I am using the same code that was working before but I changed the server and gpu I run my code.

CUDA Version: [CUDA V12.0.140]
Compiler: [ C Compiler: /usr/bin/gcc-12 -- C++ Compiler: /usr/bin/g++-12]
Build System: [CMake, Unix Makefiles]
OS: [Ubuntu 24.04.1 LTS]

I Verified that there are no duplicate definitions in my code.

However, the issue persists. Has anyone encountered this before, or does anyone have suggestions on how to resolve it?

Thank you in advance for your help!

Rafael Scatena
