You have to install AMD SDK 3 to get OpenCL. If you installed that, create a symlink to the file. ---

Have a look at the Github page of the miner. > **Failed to read bin/X\_base.bin** > You need to run the miner from the directroy where optiminer-zcash is in > otherwise it will not find the opencl kernel. ---

Hello Optiminer, this looks great, does it work with ZCL? ---

Ah thanks! I was using the stratum+tcp before the rest of the host which caused it to not work. ---

Did you set up the SDK using sudo? It has to be installed in the /opt folder. Check your environment settings with `$ env | grep opt` You should have a line like this: `AMDAPPSDKROOT=/opt/AMDAPPSDK-3.0` If not, reinstall the SDK using: $ sudo ./ AMD-APP-SDK-v3.0.130.136-GA-linux64.sh ---

What do you mean? I am running it in the same directory that I put optiminer-zcash dir, otherwise it wouldn’t find the ./optiminer-zcash.exe file the X\_base.bin is inside a folder called “bin” ---
