stockfish installation

[JiahaoYao]

Hi @calyri,

I followed the stockfish installation instruction to install. I can successfully make the src file. Then, I set the env val export STOCKFISH_EXECUTABLE="/home/jimmy/Downloads/stockfish-10-linux/src".

However, when I run the stockfish bot, I have the following bugs.

  File "/home/jimmy/anaconda3/envs/reconchess/lib/python3.6/site-packages/reconchess/scripts/rc_bot_match.py", line 22, in main

PermissionError: [Errno 13] Permission denied: '/home/jimmy/Downloads/stockfish-10-linux/src'

So, could you please tell me what is the right way to install the stockfish engine?

[calyri]

@JiahaoYao The stockfish executable environment variable has to point to the actual executable, not the directory that has it. Try updating your variable accordingly and let me know if this works.

@calyri acutally, this is the point I am confused about here. Could you tell me which should be executable directory?

Thank you so much!

If I understand your directories, then your environment variable should be set as:
export STOCKFISH_EXECUTABLE="/home/jimmy/Downloads/stockfish-10-linux/Linux/stockfish_10_x64

so that it points to the actual executable for your platform under the Linux folder.

Thanks @calyri !
