Eigen file does not exists when building 8.4.0

[schrummy14]

Hello,
When trying to build the 8.4.0 release, I am seeing the following message:

Downloading Eigen 'd71c30c47858effcbd39967097a2d99ee48db464'
HTTP Error 403: Forbidden
Download of module Eigen failed.
Get archive at https://gitlab.com/libeigen/eigen.git/archive/d71c30c47858effcbd39967097a2d99ee48db464.zip
and place it in the source code root folder
Run meson.py again
ninja: Entering directory `build'
ninja: fatal: chdir to 'build' - No such file or directory

I did go and manually download eigen-3.4.1 but SU2 isn't seeing this new directory:

Any help is greatly appreciated.

try doing "git submodule update"

[schrummy14]

Submodule update is working.
Seems to only be an issue if you download the source via tar.gz or zip and not if you git clone it.

[pcarruscag]

ok then clone with git for now

[schrummy14]

Sounds good.
Did you want to leave this open for now until the .tar.gz/zip download is working?
If not, good to close.

[pcarruscag]

I merged a fix into the develop branch, you can try again if you download the develop code instead of the master/release version.

[schrummy14]

Fix worked for me.
Thank you.
Good to close if no other info is needed.
