Re: I'm not very happy with the do {} while() statement in C

C++ vs. C; OOP vs. Procedural; Global vs. Local. These are different and unrelated things. You can use C and write OOP. You can use C++ and use Procedural. You can use lots of globals or none, in C or C++. Whatever you do, never be religious about it. Writing code that has 0 global variable for the...

Re: Tucano 7.00 Release - SMP version

Sorry to hear that. I downloaded WB2UCI. It has an option to send commands to engine using InitString. If you want to give another try, use the following below: [OPTIONS] Program=tucano_w64.exe InitString=option Threads=8\noption Hash=512\n This setup should send the threads and hash information dir...

Re: Tucano 7.00 Release - SMP version

Hi, I am not familiar with WB2UCI, but it looks it should send the parameters using the comand line.

should the line be enclosed in quotes? e.g:

Program="tucano_w64.exe -hash 1024 -threads 8"

Hope this helps.

Re: Tucano 7.00 Release - SMP version

Thanks for the new release! A no popcount 64 bit compile would be nice. Guenther Hi Guenther, Sorry, this is probably unintentional, I didn't use specific popcount feature. I used the gcc compiler, I need to review the compile parameters. Let me take a look. Alcides. Guenther and Graham, I recompil...

Hi Guenther,

Sorry, this is probably unintentional, I didn't use specific popcount feature.
I used the gcc compiler, I need to review the compile parameters.
