Building in msys2 ... Invalid configuration x86_64-pc-msys': system msys' not recognized

[kingaj12]

Following instructions for the windows build. Installed msys2, downloaded package from git, but configure fails with:

configure: loading site script /etc/config.site
/etc/config.site: line 23: config.site:23: default build_alias set to x86_64-pc-msys: command not found
/etc/config.site: line 30: config.site:30: default prefix set to /usr: No such file or directory
checking for svnversion... yes
checking build system type... Invalid configuration `x86_64-pc-msys': system `msys' not recognized
configure: error: /bin/sh ../config.sub x86_64-pc-msys failed

Solved! The solution is to follow the instructions on the Msys2 install page ;). Particularly,

pacman -Syuu

Ah, but now I had to install some more things. I followed the instructions (well, most of them) on

http://www.math.ucla.edu/~wotaoyin/windows_coding.html

I guess this is all good now? If there are things missing from documentation, let me know. I'm slowly trying to document all of these subtle details.

I have an error similar to this one. What should I do?

Did you follow the instructions here?

https://coin-or.github.io/user_introduction#windows-1

The important part is the argument --build=x86_64-w64-mingw32 to coinbrew, which is specifically to mitigate the invalid configuration error. The other errors there probably won't cause any issues.

Hello,

I am having similar problem in Windows 11 too:

$ ./configure
configure: loading site script /etc/config.site
checking build system type... Invalid configuration `x86_64-pc-msys': system `msys' not recognized
configure: error: /bin/sh ./config.sub x86_64-pc-msys failed

So here is what I did:

1. Install MSYS2 (https://www.msys2.org/), run ‘MSYS2 MinGW 64-bit’. Run

pacman -S binutils diffutils git grep make patch pkg-config 
pacman -S mingw-w64-x86_64-gcc
pacman -S mingw-w64-x86_64-gcc-fortran
pacman -S mingw-w64-x86_64-lapack mingw-w64-x86_64-metis

2. Downloaded Ipopt-3.12.13.zip from (http://www.coin-or.org/download/source/Ipopt).
3. Unpack the zip folder into C:\MSYS2\home\user_. Then,

cd Ipopt-3.12.13
cd ThirdParty/Blas
./get.Blas
cd ../Lapack
./get.Lapack
cd ../ASL
./get.ASL
cd ../Metis
./get.Metis

4. Downloaded the Coin-HSL Full zip folder (coinhsl-2021.05.05)
5. Unpack the zip folder into C:\MSYS2\home\user_\Ipopt-3.12.13\ThirdParty\HSL\ and rename it as coinhsl
6. Then compile by running

mkdir Ipopt-3.12.13/build
cd Ipopt-3.12.13/build
../configure

And I got the error above. Could someone please advise how do I get around this?

Thank you.

try

wget 'http://git.savannah.gnu.org/gitweb/?p=config.git;a=blob_plain;f=config.guess;hb=HEAD' -O './config.guess'
wget 'http://git.savannah.gnu.org/gitweb/?p=config.git;a=blob_plain;f=config.sub;hb=HEAD' -O './config.sub'

./configure

to solve the config.sub error
