Instructions for compiling cpuminer-opt for Windows.
Thwaw intructions nay be out of date. Please consult the wiki for
the latest:

Windows compilation using Visual Studio is not supported. Mingw64 is
used on a Linux system (bare metal or virtual machine) to cross-compile

Additionally, install mingw-w64.
sudo apt-get install mingw-w64
sudo apt-get install mingw-w64 libz-mingw-w64-dev
2. Create a local library directory for packages to be compiled in the next
step. Suggested location is $HOME/usr/lib/
$ mkdir $HOME/usr/lib
3. Download and build other packages for mingw that don't have a mingw64
version available in the repositories.
Download the following source code packages from their respective and
respected download locations, copy them to ~/usr/lib/ and uncompress them.
openssl
curl
gmp
openssl: https://github.com/openssl/openssl/releases
In most cases the latest vesrion is ok but it's safest to download
the same major and minor version as included in your distribution.
curl: https://github.com/curl/curl/releases
Run the following commands or follow the supplied instructions.
Do not run "make install" unless you are using ~/usr/lib, which isn't
recommended.
gmp: https://gmplib.org/download/gmp/
Some instructions insist on running "make check". If make check fails
it may still work, YMMV.

You can speed up "make" by using all CPU cores available with "-j n" where
n is the number of CPU threads you want to use.

Create a release directory and copy some dll files previously built.
This can be done outside of cpuminer-opt and only needs to be done once.
If the release directory is in cpuminer-opt directory it needs to be
recreated every a source package is decompressed.
Adjust for gcc version:

Create a link to the locally compiled version of gmp.h
ln -s $LOCAL_LIB/gmp-version/gmp.h ./gmp.h
$ ln -s $LOCAL_LIB/gmp-version/gmp.h ./gmp.h
$ ./autogen.sh
Configure the compiler for the CPU architecture of the host machine:
CFLAGS="-O3 -march=native -Wall" ./configure $CONFIGURE_ARGS
or cross compile for a specific CPU architecture:
CFLAGS="-O3 -march=znver1 -Wall" ./configure $CONFIGURE_ARGS
This will compile for AMD Ryzen.
You can compile more generically for a set of specific CPU features if you know what features you want:
CFLAGS="-O3 -maes -msse4.2 -Wall" ./configure $CONFIGURE_ARGS
This will compile for an older CPU that does not have AVX.
You can find several examples in README.txt
If you have a CPU with more than 64 threads and Windows 7 or higher you can enable the CPU Groups feature by adding the following to CFLAGS:
"-D_WIN32_WINNT=0x0601"
Once you have run configure successfully run the compiler with n CPU threads:
$ make -j n
Copy cpuminer.exe to the release directory, compress and copy the release directory to a Windows system and run cpuminer.exe from the command line.
Run cpuminer
In a command windows change directories to the unzipped release folder. to get a list of all options:

Command options are specific to where you mine. Refer to the pool's instructions on how to set them.
