Trouble with linker on yolo plugin x86 #598

Closed sgriset closed 1 year ago

sgriset commented 1 year ago

I'm building the yolo plugin for x86 compute architecture 86 (Cuda 11.8 & TensorRT-8.5.2.2). The compile has a if few warning but the linker is giving me the following message:

/usr/bin/ld: skipping incompatible /usr/local/TensorRT-8.5.2.2/lib/libnvinfer.so when searching for -lnvinfer /usr/bin/ld: skipping incompatible /usr/local/TensorRT-8.5.2.2/lib/libnvparsers.so when searching for -lnvparsers /usr/bin/ld: skipping incompatible /usr/local/TensorRT-8.5.2.2/lib/libnvinfer_plugin.so when searching for -lnvinfer_plugin

Any thoughts?

Could this be a problem of mismatching TensorRT and CUDA libraries? If that's the case, you should remove the incompatible library and install a proper one instead.

Take "TensorRT 8.5 GA Update 2" as an example, NVIDIA offers the libraries for either "CUDA 11.x" or "CUDA 10.2". Make sure you choose the correct one.

You were correct there was some mix up in libraries (cuda and tensorrt). Since the server I'm using is used by several developers I decided to use a cuda and tensorrt container from NVIDIA's catalog. The plugin compiled and linked cleanly. Thank you for your help.
