@dbermond Thank you for the prompt response and resolution! Once I reinstalled that package, this one was successfully built

@FuzzyAtish You need to rebuild python-onnx against protobuf 3.20.x, as protobuf got a soname bump. Remember that you must carefully take care of all the needed AUR rebuilds, otherwise your AUR packages becomes broken as you could see.

Hello, I'm receiving the following error when running makepkg -si

Did anyone else come across this by any chance?

@Draghi Package updated. Thanks for the notice and for appreciating the package.

trtexec does not work anymore because of a missing library: [E] [TRT] 6: [libLoader.h::DynamicLibrary::49] Error Code 6: Internal Error (Unable to load library: libnvinfer_builder_resource.so.8.2.1)

Please add it to PKGBUILD at package_tensorrt(): cp -dr --no-preserve='ownership' "TensorRT-${pkgver}/lib"/libnvinfer_builder_resource.so* "${pkgdir}/usr/lib"

Thanks for maintaining this package!

@nxxxx Take a look at the following issue: https://github.com/NVIDIA/TensorRT/issues/1064

tldr: if you want to manually install nvrtc for cuda 11.1 it works with cuda 11.2, but otherwise you need the nvrtc version provided in cuda 11.1, which means you need 11.1 for tensorrt as of now.

tensorrt 7.2.3 is capable for cuda 11.2, could you remove the version constraint of cuda? thanks.

@ilpanich As you could see, it does not build against cuda 11.2. The closed source components (downloaded from the nvidia website) strictly links to cuda 11.1 libraries and this cannot be changed, since the files are pre-compiled. So, the current source file for tensorrt 7.2.2.3 is not for cuda 11.2, but for 11.1 only. There is nothing to be fixed here, as the package is building fine. It just requires cuda11.1 from the AUR.

Despite NVIDIA says that the tarball is valid both for CUDA 11.1 & 11.2 ("TensorRT 7.2.2 for Linux and CUDA 11.1 & 11.2"), it seems not to build correctly with the latter. Will it be fixed?

collect2: error: ld returned 1 exit status make[2]: [parsers/onnx/CMakeFiles/getSupportedAPITest.dir/build.make:125: parsers/onnx/getSupportedAPITest] Error 1 make[1]: [CMakeFiles/Makefile2:1194: parsers/onnx/CMakeFiles/getSupportedAPITest.dir/all] Error 2

@gsiolas cuda 11.1 broke this package. The nvidia pre-compiled binary files depends on libraries from cuda 11.0. Reverting to use only the pre-compiled files without without building the open source components (as it was made before) will not work because there would still be pre-compiled binary files linking to cuda 11.0 libraries. Workaround is to usa cuda 11.0 if you are willing to, or wait for nvidia to release a tensorrt version that supports cuda 11.1.
