Request Cfish dev with BMI2 support

[Nordlandia]

I have Cfish with popcnt support, although BMI2 is faster.

You need to read only first 3 sentences from this link -
https://github.com/glinscott/fishtest/w ... on-Windows ;
and do it:

download and install MSYS2, use the 64 bit or 32 bit installer according your operating system and follow the official instruction to update the MSYS2 packages (simply: a. update the core packages executing pacman -Syuu, when requested close the windows pushing the top right X button b. open a MSYS2 MinGW 64-bit shell and update the others packages executing pacman -Syuu);

After that all is simple:

Build Cfish writing and executing this bash script

64 bit Windows: use a MSYS2 MinGW 64-bit shell

#!/bin/bash
# makefish.sh

# install packages if not already installed
unzip -v &> /dev/null || pacman -S --noconfirm unzip
make -v &> /dev/null || pacman -S --noconfirm make
g++ -v &> /dev/null || pacman -S --noconfirm mingw-w64-x86_64-gcc

# download the Cfish source code
wget https://github.com/syzygy1/Cfish/archive/master.zip
unzip master.zip
cd Cfish-master/src

# build the cfish executable
# to speedup the building process you can keep only the section that fits your CPU architecture

# build the binary for CPU with bmi2 instruction (e.g. Intel Haswell or newer)
if [ "$(g++ -Q -march=native --help=target | grep mbmi2 | grep enabled)" ] ; then
make profile-build ARCH=x86-64-bmi2 COMP=mingw
strip cfish.exe
mv cfish.exe ../../cfish_x64_bmi2.exe
make clean
fi

cd

And you will find Cfish engine here:
C:\msys64\home\<your name>

Oops, I made two binaries without bmi support.

Don't bother with the download, but you can use my makefile and it will work on Windows.

Some simple things cause problems.
Like, in the makefile, you have to change the name of the binary from cfish to cfish.exe for windows.
I guess it is something simple like that.

It messed up my directory, had to uninstall whole msys64.

Latest cfish with bmi2 is fine.

After last Fix compilation under MingW, method with MSYS 2 works perfect

The problem is present on my end. I reinstalled MSYS2 and updated packages, then pasting the script.

Is something else needed beside MSYS2?
