TensorRT v9.2 installation error due to CUDA version. ""-- The CUDA compiler identification is unknown""

[jamil-z]

Hello everyone, I'm trying to install TensorRT version 9.2. I followed the requirements and switched to CUDA 12.2 on a 16GB GPU machine running Ubuntu 20.

When I run the command: cmake .. -DTRT_LIB_DIR=$TRT_LIBPATH -DTRT_OUT_DIR=pwd/out

I get the following error: (venv_tensorrt) azureuser@myUser1:~/cloudfiles/code/Users/myUser/tensorrt/TensorRT/build$ cmake .. -DTRT_LIB_DIR=$TRT_LIBPATH -DTRT_OUT_DIR=pwd`/out Building for TensorRT version: 8.6.1, library version: 8 -- The CUDA compiler identification is unknown -- Check for working CUDA compiler: /usr/bin/nvcc -- Check for working CUDA compiler: /usr/bin/nvcc -- broken CMake Error at /usr/local/share/cmake-3.15/Modules/CMakeTestCUDACompiler.cmake:46 (message): The CUDA compiler

"/usr/bin/nvcc"

is not able to compile a simple test program.

It fails with the following output:

The output of my command: nvcc --version

is as follows: nvcc: NVIDIA (R) Cuda compiler driver Copyright (c) 2005-2023 NVIDIA Corporation Built on Tue_Jun_13_19:16:58_PDT_2023 Cuda compilation tools, release 12.2, V12.2.91 Build cuda_12.2.r12.2/compiler.32965470_0

From what I understand, it's an error related to CUDA not recognizing its installation correctly, but I've been trying to solve it and can't pinpoint the specific cause. Please, if anyone could help me with this, I would appreciate it.
