From 0171b506ec96e2b8c8fcc7758cd5624ad26c0552 Mon Sep 17 00:00:00 2001 From: proukornew Date: Sat, 19 Jun 2021 00:52:46 +0300 Subject: [PATCH] Fix for Cygwin's environment build-profile (fixed) 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 https://github.com/official-stockfish/Stockfish/pull/3569 No functional change --- src/Makefile | 5 +++-- 1 file changed, 3 insertions(+), 2 deletions(-) diff --git a/src/Makefile b/src/Makefile index 33a270fe..bf3c3560 100644 --- a/src/Makefile +++ b/src/Makefile @@ -883,14 +883,15 @@ clang-profile-use: all gcc-profile-make: + @mkdir -p profdir $(MAKE) ARCH=$(ARCH) COMP=$(COMP) \ - EXTRACXXFLAGS='-fprofile-generate' \ + EXTRACXXFLAGS='-fprofile-generate=profdir' \ EXTRALDFLAGS='-lgcov' \ all gcc-profile-use: $(MAKE) ARCH=$(ARCH) COMP=$(COMP) \ - EXTRACXXFLAGS='-fprofile-use -fno-peel-loops -fno-tracer' \ + EXTRACXXFLAGS='-fprofile-use=profdir -fno-peel-loops -fno-tracer' \ EXTRALDFLAGS='-lgcov' \ all -- 2.39.2
