Compling Stockfish on Windows 10-64bit using cygwin

[JohnS]

Does anyone know how to compile Stockfish on Windows 10-64bit using Cygwin? Are there instructions anywhere?

Thanks.

I guess it is just like MSYS2, another Posix layer for Windows.
Just go to the source folder and type:
make
and you will get instructions on what to do.

Hi Dann

I tried

make profile-build ARCH=x86-64-modern COMP=mingw

but got errors:

In file included from thread.h:35:0,
from evaluate.cpp:31:
thread_win32.h:61:14: error: 'condition_variable_any' in namespace 'std' does not name a type
typedef std::condition_variable_any ConditionVariable;
^
In file included from evaluate.cpp:31:0:
thread.h:46:3: error: 'ConditionVariable' does not name a type
ConditionVariable cv;
^
thread.h:49:8: error: 'thread' in namespace 'std' does not name a type
std::thread stdThread;
^
make[2]: *** [<builtin>: evaluate.o] Error 1

Do you know what the problem is?

Thanks.

Did you try it with "COMP=gcc" (which is the default and can also be omitted)?

Hi Sven

It still gives the same errors with gcc.

Which Stockfish version are you trying to compile? I had no problems to compile under CygWin with a recent dev version from 26-dec-2018.

EDIT: for some reason the _WIN32 macro is defined for you in your setup, that should not be the case when using CygWin.

It looks like he is using an old version of gcc.

See this:
thread.h:49:8: error: 'thread' in namespace 'std' does not name a type
std::thread stdThread;

That's an old compiler.

Thanks Dann and Sven. I had not set the path to Cygwin and that was causing the problem. It compiles now but I can't run it outside Cygwin without it needing to find cygwin1.dll. Is there a switch to make a standalone binary that can be used without the dll, like the abrok ones?

Thanks.

This question is answered in the Cygwin FAQ.

That's not the whole story, though. There in fact used to be such a compiler flag ( -mno-cygwin) but it was removed a few years ago. Just another reason the recommended way to build SF on Windoze is with MSYS2 and MinGW and that explicitly allows for static builds, with no additional DLLs required. I never had any problems building SF with this combo, although it's been a while since I did my own SF builds; and earlier I had no issues using MinGW on its own, which is about just as easy and painless.

Thanks for the link Tirsa. It works well.

Off topic for Unix gurus (not me ): How does the line

unzip -v &> /dev/null || pacman -S --noconfirm unzip

work in checking if unzip is installed and installing it if it is not?
