Eigen3 website down; where to get Eigen?

[Alex Teti]

I am attempting to do the installation, but http://eigen.tuxfamily.org/ is unavailable for some reason. Where else can I get this library, and how?

[Freya the Goddess]

Hope you are using Linux.

https://github.com/glanzkaiser/glanzshamzs/blob/main/Eigen/eigen-3.4.0.tar.gz

or you can use wget from the official source, I get it from here:

wget https://gitlab.com/libeigen/eigen/-/archive/3.4.0/eigen-3.4.0.tar.gz

Extract it, then enter the directory.

mkdir build &&

cd build &&
cmake -DCMAKE_INSTALL_PREFIX=/opt/hamzstlib \
-DCMAKE_INSTALL_LIBDIR=/opt/hamzstlib \
-Wno-dev .. &&
 make

Thanks! No, I'm using Windows; is that a problem?

[Freya the Goddess]

The file is in .tar.gz (which means it is for Linux)

You can try to use Virtual Box and install a Linux in Windows if you want.

Freya, you are providing misleading information!  There is no problem whatsoever to work with tarball archives under Windows. Simply use 7zip.

 

Alex, Windows is definitely not a problem.

The issue you are facing is temporary. The TuxFamily site which hosts Eigen is currently experiencing a network outage (https://www.tuxfamily.org/). This will likely be resolved soon.

You can get the 3.4.0 distribution from the Eigen GitLab page (https://gitlab.com/libeigen/eigen/-/releases) in different formats.

Note also that Eigen is a headers-only library. For use with Chrono you do *not* need to build anything!

Yeah, I already extracted it with 7 zip. I was wondering what the problem was. Cool, thanks; nice to now the outage for the TuxFam site is temporary too.

Sorry for that, I do not use Windows for years, I thought that Windows can't use tar.gz
