Strange Stockfish behavior?

[royb]

Things are almost there now with the fixed Makefile. However there is an issue with EGTB. I added 'USE EGTB' to my command line for the make command and I get errors about egtb/gtb-probe.h no found. I created symlinks in egtb directory to ../gtb-probe.h (and a couple others if memory serves). However now I get this error:

The unhappiness starts with: /usr/bin/ld: cannot find -lgtb

I'm not a Makefile guy and not a git person so pulling the source from the git repository is not something I'm knowledgeable about.

Thanks.

1. cd src/egtb
2. make (this will build the libgtb.a file that you need)
3. cd ..
4. make [ARCH]

that should be all you need to do. You don't need to add USE_EGTB to the command line, but you do have to build the static library libgtb first, and then just run the stockfish makefile. It Should Just Work©.

The src directory is empty, there is no egtb directory (or anything else!) in there.

Sorry I'm so clueless on this.

OK, step by step:

1. Un7z the Stockfish_211_PA_GTB_Gran2c.7z file. Verify that there are files in the src directory.
2. Open a console window and navigate to the "src" directory in the folder you unpacked.
3. Type 'cd egtb'
4. Type 'make'
5. Type 'cd ..' (you're now back in src)
6. Type 'make build ARCH=[archname]' where [archname] is one of the architectures specified in the makefile -- you probably want x86-64 or x86-64-modern, or x86-32 if you need 32-bit.

If that works, you can consider making an optimized build with 'make popcnt-profile-build ARCH=[archname]'.

Step 1. I ran this: 7z e Stockfish_211_PA_GTB_Gran2c.7z and expanded this into the directory /home/roy/chess/SF-2.1.1-PA-GTB (already existing and empty directory). There are NO source files in the src directory. They are all in the directory above src in /home/roy/chess/SF-2.1.1-PA-GTB and not in /home/roy/chess/SF-2.1.1-PA-GTB/src .

Sounds like your 7z program isn't expanding the archive correctly. Try '7z ex' instead of just '7z e'.

7z x Stockfish*.7z that worked and I moved the resulting directory into the SF-2.1.1-PA-GTB directory.

OK, now the last step of your process yields this:

And we are back again to /usr/bin/ld cannot find -lgtb

Getting closer. I did not put USE_EGTB on the command line this time for the make though I would like to be able to use GTBs in the end.

I thought I did but I redownloaded your Makefile.zip file and unzipped it into the src directory and re-ran make and got the same result ...

[Jeremy Bernstein]

Sorry, I'm an ass. I posted the wrong Makefile (pre-save). The correct one is attached. Sorry to waste your time.

[BB+]

Sounds like your 7z program isn't expanding the archive correctly. Try '7z ex' instead of just '7z e'.

I had the same problem at first. I just ran "7za e <name>", and had to realise that you need to add the x option to get the directory structure to also be extracted:

Code: Select all

  e: Extract files from archive (without using directory names)
  x: eXtract files with full paths

[It initially gave me a query about overwriting Makefile (the one from egtb/), which led me to wonder was going on].

Thanks Jeremy for these Stockfish 2.11 pa GTB Gran series. Thanks to others involved; Uly, BB, etc /9sorry if I missed someone).
