getting error in cmake

[nilsfriess]

Can you tell us more about your environment? How are you calling CMake, which compiler are you using etc.?

[garadeaniket]

cmake -DCMAKE_INSTALL_PREFIX=/path/to/build -DCMAKE_C_COMPILER=/path/to/bin/gcc -DCMAKE_CXX_COMPILER=/path/to/bin/g++ -DCLANG_EXECUTABLE_PATH=path/to/bin/clang++ -DCLANG_INCLUDE_PATH=/path/to/include/clang/ -DCMAKE_CXX_COMPILER=/path/to/bin/clang++ -DBOOST_ROOT=/path/to/build/ -DWITH_CUDA_BACKEND=ON
-DCUDA_TOOLKIT_ROOT_DIR=/path/to/cuda -DACPP_VERSION_SUFFIX="-"

gcc version 12.2.0
clang version 15.0.7

You are passing two different compilers for CMAKE_CXX_COMPILER, not sure if this causes the problem, but I guess that's not what you want.

Can you try

cmake -DCMAKE_INSTALL_PREFIX=/path/to/install -DCMAKE_CXX_COMPILER=clang++ -DBOOST_ROOT=/path/to/boost -DWITH_CUDA_BACKEND=ON -DCUDA_TOOLKIT_ROOT_DIR=/path/to/cuda -DACPP_VERSION_SUFFIX="-"

Make sure to clean you build directory before that.

Note that CMAKE_INSTALL_PREFIX should be the path where you want the project to be installed. And BOOST_ROOT should point to the path where boost is installed (if you're on Ubuntu or similar and installed boost via apt-get then you probably don't need to specify this manually).

I tried with the above command u mentioned but getting the same error and also nothing has been generated in build folder .The error seems more of missing package (Findfilesystem).Any idea about this?

[nilsfriess]

Could you please post the full CMake command you're using again and the complete output you're getting. And could you give us some details about your build environment, in particular your OS?

We are testing with clang15 in CI and I also just tried to build AdaptiveCpp with gcc 12, which also worked.
