Cannot find CUDA installation

[rickyi89]

Hi everyone,

sorry for bothering you all, but I'm not able to build the code on Ubuntu 17.04.

I'm using CUDA 8.0 and Clang 4.0 on GTX 1050Tis and I issue these commands:

cmake . -DCUDA_COMPILER=clang -DCUDA_ARCH=61

-- Looking for pthread.h -- Looking for pthread.h - found -- Looking for pthread_create -- Looking for pthread_create - not found -- 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 CUDA: /usr (found suitable version "8.0", minimum required is "7.5") -- Found OpenSSL: /usr/lib/x86_64-linux-gnu/libssl.so;/usr/lib/x86_64-linux-gnu/libcrypto.so (found version "1.0.2g") -- Configuring done -- Generating done -- Build files have been written to: /home/riccardo/mining/xmr-stak-nvidia

and then

make install Scanning dependencies of target xmr-stak-nvidiaCrypto [ 4%] Building C object CMakeFiles/xmr-stak-nvidiaCrypto.dir/crypto/c_blake256.c.o [ 9%] Building C object CMakeFiles/xmr-stak-nvidiaCrypto.dir/crypto/c_groestl.c.o [ 14%] Building C object CMakeFiles/xmr-stak-nvidiaCrypto.dir/crypto/c_jh.c.o [ 19%] Building C object CMakeFiles/xmr-stak-nvidiaCrypto.dir/crypto/c_keccak.c.o [ 23%] Building C object CMakeFiles/xmr-stak-nvidiaCrypto.dir/crypto/c_skein.c.o [ 28%] Building C object CMakeFiles/xmr-stak-nvidiaCrypto.dir/crypto/soft_aes.c.o [ 33%] Linking C static library libxmr-stak-nvidiaCrypto.a [ 33%] Built target xmr-stak-nvidiaCrypto Scanning dependencies of target xmr-stak-nvidiaCuda [ 38%] Building CXX object CMakeFiles/xmr-stak-nvidiaCuda.dir/nvcc_code/cuda_core.cu.o clang: error: cannot find libdevice for sm_61.

I've tried to unistall and reinstall CUDA, but it didn't change a bit.

Thank you in advance!

[zjhxmjl]

i get the same problem,pls how to modify ?

[psychocrypt]

pease run 'make VERBOSE=1' and post the output

[madelinecameron]

I've been having this issue as well! I finally got it to build (somehow) after reading a bunch of other issues.

git clean -fdx
export CXX=/usr/bin/clang++
export CC=/usr/bin/clang
cmake . -DCUDA_ARCH=61
make install

clang-3.8 cuda 9

[madelinecameron]

I kept using -DCUDA-COMPILER=clang and when I dropped using it, CMake started complaining about me using clang-5 or clang-4 so I dropped back to clang 3.8 like what was suggested in another issue.

[warptoy]

Thanks to madelinecameron I was able to compile it using CUDA 9.0 and clan-3.8.

Anyway I had to move to CUDA 8.0 as I've discovered that Debian Unstable is stuck to driver release 375.82 (CUDA 8.0 only). Then I've spent another day trying to fix all the new problems I had with that configuration. Finally I was able to compile xmr-stack-nvidia using CUDA 8.0 (from NVidia, not from repo) and gcc-5.0. For some reason nvidia-cuda-* for debian and ubuntu didn't work anymore.

[rickyi89]

Got it to work thanks to @madelinecameron suggestion. After that i got the error of undeclared identifier 'float128', solved adding set(CMAKE_CXX_FLAGS "${CMAKE_CXX_FLAGS} -DSTRICT_ANSI__") after project definition to CmakeLists.txt as found pn stackoverflow.

Thanks everyone!

[cbesot]

All that I tried doesn't work. From gcc problem to clang problem passing by cuda problem.

At the end, I made as above : cuda9 and clang-3.8 export CC=/usr/bin/clang-3.8 export CXX=/usr/bin/clang++-3.8 cmake . -DCUDA_COMPILER=clang

So, no solution.

[madelinecameron]

Try targeting your cuda architecture directly with the -DCUDA_ARCH flag.

Works! Without specifying -DCUDA_COMPILER=clang So:

git clean -fdx
export CC=/usr/bin/clang-3.8
export CXX=/usr/bin/clang++-3.8
cmake . -DCUDA_ARCH 61

[novadeviator]

thanks to everyone this last bit helped me too to get it compile without any extra downloads on Ubuntu 17.04.

just the last line shoudl be -DCUDA_ARCH=61, so the final thing was:

git clean -fdx
export CC=/usr/bin/clang-3.8
export CXX=/usr/bin/clang++-3.8
cmake . -DCUDA_ARCH=61
