Run In Windows Msys2 Mingw64 x64

To Install OpenSSL and find <openssl/ssl.h> <openssl/opensslconf.h>.

Download MSYS2 RUN Mingw64

Run "pacman -S mingw-w64-x86_64-toolchain", and install gcc.

Run "pacman -S make".

Download Source Code From https://github.com/openssl/openssl

cd to folder where "config" file is.

change the prefix and openssldir to what you want.

This command "./config --prefix=/home/ssl --openssldir=/home/ossl shared zlib"

= "./Configure --prefix=/home/ssl --openssldir=/home/ossl shared zlib"

./config --prefix=/home/ssl --openssldir=/home/ossl shared zlib
make
make install

change c file to your file (In here is tls.c)

This c file include "#include <openssl/ssl.h>" line.

Currect path "C:/msys64/home/ssl/include/openssl/ssl.h" in this example.

Currect path "C:/msys64/home/ssl/bin/libcrypto-3-x64.dll" in this example.

Currect path "C:/msys64/home/ssl/bin/libssl-3-x64.dll" in this example.

Add "C:/msys64/home/ssl/bin"(dll path) to environment path or copy dll file to the path "tls.c"

gcc tls.c -I"C:/msys64/home/ssl/include/" -L"C:/msys64/home/ssl/bin" -lws2_32 -llibssl-3-x64 -llibcrypto-3-x64

Add "C:/msys64/home/ssl/bin"(dll path) to environment path or Copy dll file to the path where the ".exe" is. (a.exe)

./a

When you run exe in cmd not in msys2 shell, you need C:\msys64\mingw64\bin\zlib1.dll.

Copy it to exe path or set C:\msys64\mingw64\bin\ to environment path.
