Hello,

I am trying to use this repo to benchmark different SNARK provers on GPUs. After launching the test as described in README, i get the error below.

Thanks

Did you compile and copy the libcuda.so file to the root of the bellman directory?

druiz0992 commented 5 years ago

yes, I did.

I verified correct build by removing libcuda.so and it failed as expected. When libcuda.so is present in root bellman folder, build completes, but launching test produces the error.

By the way, I am using cmake 3.15.2 and GNU make 4.1

Hi @druiz0992, I was having the same issue, the build works but to run the test you need to add LD_LIBRARY_PATH=. to the cargo command.

Thanks. That worked for me!!
