Twooptions for compiling C and C++ , and other kinds of source code files under windows , are : the cygwin-gcc compiler , and the mingw-gcc compiler .
For source code , that uses the posix api , the cygwin-gcc compiler can be used , it provides a substantial implementation of the posix api , provided by the cygwin1.dll library .
cygwin-gcc , can also be used to compile source code , which uses the windows api . In both cases , the cygwin1.dll library , must be made available to the executing program .
For source code , that only uses the windows api , the mingw-gcc compiler can be used . The produced executable , does not depended on cygwin1.dll , it just depends on windows libraries .
To install these compilers , two unix like environment , which provide unix commands in the form of windows executables , are available , the first one is the Cygwin environment , and the second one is MSYS2 environment .
Both environment , provide both compilers , the MSYS2 environment provides a package manager , pacman , that allows the installation of packages , whereas Cygwin does not provide a package manager , package installation is done through the installer , each time a package is to be installed or removed .

MSYS2
Installation
To install MSYS2 , download the installer from the MSYS2 website , and double click it .
Click next , on the first screen , next for the install folder , next for the start menu shortcuts , after that msys2 will start installing .
Once the installation is done , three shortcuts will be created in the start menu .
One will launch the MSYS2 Mingw 64 terminal , another will launch the MSYS2 Mingw 32 terminal , and the last one will launch the MSYS2 MSYS terminal . The difference between these three launchers , is the path :
MINGW32# echo $PATH
/mingw32/bin:/usr/local/bin:/usr/bin:/bin:/c/Windows/System32:/c/Windows:/c/Windows/System32/Wbem:/c/Windows/System32/WindowsPowerShell/v1.0/:/usr/bin/site_perl:/usr/bin/vendor_perl:/usr/bin/core_perl
#Has /mingw32/bin , prepended , and is
#missing /opt/bin comparing to MSYS
#path . Differs from MINGW64 path ,
#by just the prepended directory .
MINGW64# echo $PATH
/mingw64/bin:/usr/local/bin:/usr/bin:/bin:/c/Windows/System32:/c/Windows:/c/Windows/System32/Wbem:/c/Windows/System32/WindowsPowerShell/v1.0/:/usr/bin/site_perl:/usr/bin/vendor_perl:/usr/bin/core_perl
#Has /mingw64/bin prepended ,
#and is missing /opt/bin ,
#when comparing to MSYS .
#Only differs by the prepended
#path , from MINGW32 .
MSYS# echo $PATH
/usr/local/bin:/usr/bin:/bin:/opt/bin:/c/Windows/System32:/c/Windows:/c/Windows/System32/Wbem:/c/Windows/System32/WindowsPowerShell/v1.0/:/usr/bin/site_perl:/usr/bin/vendor_perl:/usr/bin/core_perl
Click on finish , this will run the MSYS2 MSYS terminal .
From the opened terminal , and to install themingw-w64 compiler , and the cygwin-gcc compiler , first issue this command :
$ pacman --sync --refresh --sysupgrade

Package management using pacman
Intro
pacman is the package manager used by MSYS2 , it installs the packages to a subdirectory in the MSYS2 installation directory , which is by default C:\msys64 .
pacman has three repositories configured , from which packages can be installed .
The first one is the msys2 repository , which related directories are /etc and /usr , and which installed packages , are accessible using the terminal MSYS2 MSYS . This repository contains the Cygwin compiler , which produces windows executable , dependent on the cygwin1.dll library .
An example of an application , installed from the msys2 repository , is emacs .
$ which emacs
#Path of the accessible
#emacs .
/usr/bin/emacs
Thelatter two are the mingw32 , and mingw64 repositories , which related directories are : /mingw32 , and /mingw64 .
Their installed packages are accessible from MSYS2 MinGW 32-bit and MSYS2 MinGW 64-bit shortcuts .
An example of an application installed from the mingw64 repository , is emacs .
$ which emacs
#Path of the accessible
#emacs .
/mingw64/bin/emacs
Other directories found under C:\msys64 , and related to posix are : /bin , /dev , /home , /opt , /proc , /tmp , /var . The windows disk drives , can be accessed using /c or /d or …
The pacman --sync operation is used to synchronize the packages . The packages synchronization operation , must be followed by an option , which is the option , of what this operation will be doing .
Updating packages
Toupdate the package database , --sync --refresh , can be used , and to force a refresh of the package database , even if it is up to date , --sync --refresh --refresh can be used .
$ pacman --sync --refresh
#--sync operation is used for
#package synchronization . Package
#synchronization take some options .
#The --refresh option is used to
#refresh the database .

Toupgrade all the packages which are out of date , --sync --sysupgrade can be used .
$ pacman --sync --refresh --sysupgrade

Searching , and getting packages information
To search for a package , one of these following options can be used .
--sync --groups , will list all the available groups . A group is a set of related packages , that can be installed together . An optional group name can be provided , in this case , the packages , that belong to this group , are displayed .
$ pacman --sync --groups
#--sync operation is used to
#sync the packages . It takes
#options , the --groups option
#will list all the available
#groups of packages .
