Solved cygwin mingw msys mingw-w64 msys2

I am trying to build some open source library. I need a package management system to easily download the dependencies. At first I am using MinGW and MSYS. But the included packages are limited. Someone told me to use Mingw-w64 and MSYS2.

I downloaded the mingw-w64-install from here. When running, it reports the following error. How can I fix it?

And by the way, from the Mingw-w64 download page, I see a lot of download links. Even Cygwin is listed. How are Cygwin and Mingw-w64 related?

My current understanding is, in the time of MinGW and MSYS, MSYS is just a nice addon to MinGW, while in Mingw-w64 + MSYS2, MSYS2 is stand-alone and Mingw-w64 is just a set of libraries it can work with. Just like Cygwin can download many different packages.

Unfortunately, the MinGW-w64 installer you used sometimes has this issue. I myself am not sure about why this happens (I think it has something to do with Sourceforge URL redirection or whatever that the installer currently can't handle properly enough).

Anyways, if you're already planning on using MSYS2, there's no need for that installer.

Download MSYS2 from this page.
After the install completes, click on the MSYS2 UCRT64 in the Start menu (or C:\msys64\ucrt64.exe).

If done correctly, the terminal prompt will say UCRT64 in magenta letters, not MSYS.
Update MSYS2 using pacman -Syuu. If it closes itself during the update, restart it and repeat the same command to finish the update.

You should routinely update your installation.
Install the toolchain: (i.e. the compiler and some extra tools)
```
pacman -S mingw-w64-ucrt-x86_64-toolchain
```
Install any libraries/tools you may need. You can search the repositories by doing
```
pacman -Ss name_of_something_i_want_to_install
```
e.g.
```
pacman -Ss gsl
```
and install using
```
pacman -S package_name_of_something_i_want_to_install
```
e.g.
```
pacman -S mingw-w64-ucrt-x86_64-gsl
```
and from then on the GSL library will be automatically found by your compiler!

Make sure any compilers and libraries you install have this package prefix: mingw-w64-ucrt-x86_64-. Only use unprefixed packages for misc command-line utilities (such as grep, sed, make, etc), unless you know what you're doing.
Verify that the compiler is working by doing
```
gcc --version
```

If you want to use the toolchains (with installed libraries) outside of the MSYS2 environment, all you need to do is add C:/msys64/ucrt64/bin to your PATH.

MSYS2 provides several compiler flavors, UCRT64 being one of them. It should be a reasonable default.

Thanks. How can I get the canonical name of a package that pacman can recognize? – Deuteron 6/5, 2015 at 12:30

Will it work if you install both 32 and 64 bit toolchains simultaneously? – Shwalb 28/9, 2015 at 18:0

@Colonel yes, it will install the toolchains (and any 3rd party libraries you install) in separate directories (/mingw32 and /mingw64). – Amathiste 29/9, 2015 at 6:23

To use in MSYS2 shell I had to do: PATH=/mingw64/bin:$PATH – Wedurn 30/3, 2016 at 22:55

@Toby I agree they take "the Arch Way" in explaining things, i.e. read the Arch wiki on pacman and you'd know nearly the same. A beginner's setup might be useful, although it is now on SO which should turn up on Google quite quickly :). (read this as: keep upvoting this answer :P) – Amathiste 6/5, 2016 at 12:49

Reading the pacman documentation took me about half an hour to figure out how to actually install things instead of just listing them, LOL - Much more used to yum or apt-get! – Tribute 6/5, 2016 at 14:19

@Tribute you need to work on your reading skills: wiki.archlinux.org/index.php/…. – Amathiste 6/5, 2016 at 14:23

@Amathiste Ah that is indeed easier! I was looking at archlinux.org/pacman/pacman.8.html – Tribute 6/5, 2016 at 14:35

Using pacman to install mingw-w64 is a great advice. I faced the same issue while trying to install mingw-w64 behing a proxy. Installing MSYS2 first, setting environment variables for the proxy like superuser.com/questions/713582/… and following your answer works perfectly. – Bairam 19/8, 2016 at 11:22

Thanks so much for this post - this should seriously replace the windows compilation guides. Is there anything you can add to this about cross compiling? When using MSYS2 and following the guide, there are issues with using the --cross-prefix=i686-w64-mingw32-. Perhaps this is unnecessary with how MSYS2 installs the gcc and instead relies on the order of environment variables specified in PATH? – Horsecar 12/3, 2017 at 4:45

In case you need cmake, you have to install pacman -S mingw-w64-x86_64-cmake and NOT cmake. Normal cmake will lack generators for minGW. – Destination 15/1, 2020 at 19:59

Regarding step 5. (Open a MinGW-w64 shell): When the tools are installed using the Chocolatey packet manager the shell must be opened manually from the directory C:\tools\msys64 – Cooky 26/5, 2020 at 23:26

Beware that this instruction is not enough to get std::thread and std::mutex working in MinGW. See here for more info. – Undies 27/10, 2020 at 23:33

Is it okay if I install mingW-w64 SEPARATELY using mingw-w64 install file, and then install MSYS2 through its x86_64 installer? – Somewhere 13/11, 2020 at 17:1

@Valsak yes, that's possible (the MSYS2 MinGW-w64 x86_64 GCC is a native compiler toolchain like any other). Just don't install the separate MinGW-w64 install inside the MSYS2 tree ir you'll mess up MSYS2's file tracking. By installing a separate toolchain, you can more easily stick to a specific GCC version, but you lose the convenience of having everyting updating as a whole. – Amathiste 15/11, 2020 at 9:47

MSYS has not been updated a long time. MSYS2 is more active, and you can download it from MSYS2. It has both the mingw and cygwin fork package.

To install the MinGW-w64 toolchain (reference):

Open the MSYS2 shell from the start menu
Run pacman -Sy pacman to update the package database
Reopen the shell, and run pacman -Syu to update the package database and core system packages
Reopen the shell, and run pacman -Su to update the rest
Install the compiler:
- For a 32-bit target, run pacman -S mingw-w64-i686-toolchain
- For a 64-bit target, run pacman -S mingw-w64-x86_64-toolchain
Select which package to install; the default is all
You may also need make. Run pacman -S make

how do i install specific MinGW-w64 version like x86_64-6.2.0-release-posix-seh-rt_v5-rev1? – Devalue 8/12, 2016 at 14:12

Does that mean the mingw installer as described here is not necessary anymore? and I should just install msys2? – Barchan 17/2, 2017 at 10:45

Link Reference is broken – Merell 11/9, 2017 at 6:59

any ideas on why msys2 shell would close itself after a second? – Thora 9/5, 2019 at 22:36

In case you need cmake, you have to install pacman -S mingw-w64-x86_64-cmake and NOT cmake. Normal cmake will lack generators for minGW. – Destination 15/1, 2020 at 19:57

Important note -- when using the pacman upgrade commands, it may show a message telling you to force close the window -- it's important to actually obey the message – Decagon 9/3, 2020 at 1:39

You can now also get the stand-alone personal build of MinGW-w64 from https://winlibs.com/ which doesn't require any installation; just extract and its ready to use. This allow having multiple toolchains on the same system (e.g., one for Windows 32-bit and another for Windows 64-bit).

MSYS2 also supports multiple toolchains per installation (and multiple installations). Winlibs is indeed easy to use, but lacks a package manager (i.e. no prebuilt libraries) and a linux-like environment (can't build stuff using Autotools). – Beitris 23/11, 2021 at 19:7

@Beitris Thanks for your insights. I'm actually working on a package manager for winlibs, and I'm making it cross-platform. – Hydrogen 23/11, 2021 at 22:15

The most straightforward way, as far as I know, is to use Chocolatey to install MinGW:

choco install mingw

Then check with the command whereis gcc. It is going to be installed in C:\ProgramData\chocolatey\bin.

one more thing, to get make working, just copie (or rename if you wish) with copy mingw32-make.exe make.exe in C:\ProgramData\chocolatey\bin.

Re "to be installed in C:\ProgramData": Doesn't that depend on the Windows version and the configuration of Windows? – Reel 10/12, 2022 at 15:13

mingw32-make and make are different things, and pretending one is the other won't do any good. – Beitris 10/12, 2022 at 21:39

Does this install pacman (the package manager)? One of the main selling points of MSYS2 is its numerous packages... – Beitris 10/12, 2022 at 21:40

mingw32-make is a version of make that has been ported to Windows with MinGW. It works in a similar way to make, but with some differences in syntax and behavior due to Windows difference. – Quattlebaum 9/4, 2023 at 18:28
