thrust_create_target dependency

[sononix]

I'm trying to build the basic example on ubuntu 20.04 > cuda 11.8 and having trouble in getting the example to compile, I had it working on an older install be for some reason Im getting the following error

CMake Error at /usr/lib/cmake/cudf/cudf-config.cmake:178 (thrust_create_target): Unknown CMake command "thrust_create_target". Call Stack (most recent call first): build/cmake/CPM_0.35.3.cmake:216 (find_package) build/cmake/CPM_0.35.3.cmake:273 (cpm_find_package) CMakeLists.txt:23 (CPMFindPackage)

Ive tried adding the library in the command line using

cmake -S . -DThrust_DIR=/home/..../thrust/thrust/cmake -B build

and setting the dependence in the cmakefile but neither approaches seem to work

set(Thrust_DIR /home/..../thrust/thrust/cmake)


the full output to screen is

sudo cmake -S . -B build -- The CXX compiler identification is GNU 9.4.0 -- The CUDA compiler identification is NVIDIA 11.8.89 -- Detecting CXX compiler ABI info -- Detecting CXX compiler ABI info - done -- Check for working CXX compiler: /usr/bin/c++ - skipped -- Detecting CXX compile features -- Detecting CXX compile features - done -- Detecting CUDA compiler ABI info -- Detecting CUDA compiler ABI info - done -- Check for working CUDA compiler: /usr/local/cuda/bin/nvcc - skipped -- Detecting CUDA compile features -- Detecting CUDA compile features - done -- Downloading CPM.cmake to /home/ms/CODE/NVIDIA/cudf/cpp/examples/basic/build/cmake/CPM_0.35.3.cmake -- Performing Test CMAKE_HAVE_LIBC_PTHREAD -- Performing Test CMAKE_HAVE_LIBC_PTHREAD - Failed -- Looking for pthread_create in pthreads -- Looking for pthread_create in pthreads - not found -- Looking for pthread_create in pthread -- Looking for pthread_create in pthread - found -- Found Threads: TRUE -- Found CUDAToolkit: /usr/local/cuda/include (found version "11.8.89")

Ive managed to build cudf from source and thrust library from source on the box, but the thrust_create_target error has me stumped
Anyone any idea to what might be causing the error

@sononix Do you need to use a custom Thrust build? I don't think cuDF supports that since we have to patch Thrust:

https://github.com/rapidsai/cudf/blob/branch-23.08/cpp/cmake/thirdparty/patches/thrust_override.json

@robertmaynard Would you have thoughts on this?

[robertmaynard]

We don't support an external Thrust due to the patches we apply.

My bad I was missing an argument in the build.sh file for the CMAKE_CUDA_COMPILER - though I'm getting blocked on the linking or ld not being able to locate nvToolsExt - it appears it is needed in the strings example and is blocking the build process

/usr/bin/ld: cannot find -lnvToolsExt collect2: error: ld returned 1 exit status gmake[2]: *** [CMakeFiles/libcudf_apis.dir/build.make:100: libcudf_apis] Error 1 gmake[1]: *** [CMakeFiles/Makefile2:89: CMakeFiles/libcudf_apis.dir/all] Error 2 gmake[1]: *** Waiting for unfinished jobs....

should it not be installed along with cuda?

@sononix Can you provide more information, or a minimal reproducer? What version are you building? I think we switched to the header-only form of nvtx in #13165 (and similar PRs elsewhere in RAPIDS), so I'm unsure what needs nvToolsExt libraries to be linked.
