Fix for Cygwin's environment build-profile
Browse files Browse the repository at this point in the history 
The Cygwin environment has two g++ compilers, each with a different problem
for compiling  Stockfish at the moment:

(a) g++.exe : full posix build compiler, linked to cygwin dll.

    => This one has a problem embedding the net.

(b) x86_64-w64-mingw32-g++.exe : native Windows build compiler.

    => This one manages to embed the net, but has a problem related to libgcov
       when we use the profile-build target of Stockfish.

This patch solves the problem for compiler (b), so that our recommended command line
if you want to build an optimized version of Stockfish on Cygwin becomes something
like the following (you can change the ARCH value to whatever you want, but note
the COMP and CXX variables pointing at the right compiler):

```
   make -j profile-build ARCH=x86-64-modern COMP=mingw CXX=x86_64-w64-mingw32-c++.exe
```

closes #3463

@snicolet There is some issue with make clean now

@SFisGOD

can you try to comment each line in lines 799-804 of Makefile in turn, and tell us which one (if any) is giving the error?

profileclean:
	@rm -rf profdir
	@rm -f bench.txt *.gcda *.gcno ./syzygy/*.gcda ./nnue/*.gcda ./nnue/features/*.gcda *.s
	@rm -f stockfish.profdata *.profraw

EXTRACXXFLAGS='-fprofile-generate="./"' \

Creates a folder with same path with stockfish src files so it's something like this

C:\Users\User\Stockfish\src\C~\Users\User\Stockfish\src

And this is where all the gcda files go. Previously, all gcda files are created in

C:\Users\User\Stockfish\src

The problem is that make clean can't get rid of this C~ folder

Same error with gcc version 10.3.0 (Rev2, Built by MSYS2 project).

Same problem in msys2 with:

  • EXTRACXXFLAGS='-fprofile-generate="."' \
  • mingw32-make.exe instead that make.exe (the former is Windows native but can have some compatibility problems)

Looks like we will not escape writing platform-specific code in the Makefile.. Any way to test in the Makefile that we are compiling on CygWin?

What happens if you set the profile directory with -fprofile-dir instead?

If that doesn't work either we could try specifying a separate subdirectory for the profile data, but that's a larger change.

That would be nice to test, probably, yes.

I note that Andreï suggests another solution (or maybe the same, unclear) in one comment of the PR:

Resolution: use mangling paths via -fprofile-*=path option

@ppigazzini Does it make any difference if you omit the double quotes? -fprofile-dir=.

Edit: if that doesn't work we can use the intel compiler profile directory: -fprofile-dir=profdir (make profileclean removes this directory already, so no more changes are needed).

@ppigazzini Could you try one last time with -fprofile-dir=profdir please?

I suspect this one is going to work but it puts the profiling data in an different directory than master so it's up to the maintainers if this is acceptable. The same directory is used by ICC though, so it isn't an outlandish change.

@gvreuls @snicolet -fprofile-dir=profdir works fine w/ msys2 and cygwin, no problem w/ a second build w/o make clean, no problem w/ make clean.
EDIT_000: works fine also on WSL2.
EDIT_001: the "profdir" folder is automatically deleted when the Makefile stops. On msys2 the "profdir" folder contains the "C~" tree of folders, msys2 correctly deals w/ any space in folder names.

-fprofile-dir=profdir works fine here and indeed the profdir directory gets deleted during step 4 (profileclean)

-fprofile-dir="." creates the "C~" folder on msys2.

It's not true. Try to refresh msys2. I have 0 problems with msys2 and dot.
@ALL But, as i said on issue page, we can use any combination of profile-generate=path or profile-dir=path. I've tested at cygwin and msys2 "." path. The folder for gcda files is good idea

@proukornew The dot solution might work for your system but it doesn't work on other people's machines. Can you confirm that the -fprofile-dir=profdir solution works for you? If it does you can make a new Pull Request with that solution and everybody's happy.
