Hello,
I’m building tvm_rpc exectuable with OpenCL. I have specified OpenCL_INCLUDE_DIR and OpenCL_LIBRARY, but I’m getting errors about undefined references to cl functions.
My cmake command(simplified):
sed -i 's/set(USE_CPP_RPC OFF)/set(USE_CPP_RPC ON)/g' config.cmake && \
sed -i 's/set(USE_OPENCL OFF)/set(USE_OPENCL ON)/g' config.cmake && \
sed -i 's/set(USE_OPENGL OFF)/set(USE_OPENGL ON)/g' config.cmake && \
echo 'set(OpenCL_INCLUDE_DIR /workspace/3rdparty/OpenCL-Headers)' >> config.cmake && \
echo 'set(OpenCL_LIBRARY /workspace/3rdparty/opencl_libs/libOpenCL.so)' >> config.cmake && \
cmake .. \
