Dear Mrtrix3 Users,

I had a problem with the ./configure command while running the Mrtrix3 installation on my linux pc running Ubuntu 22.04.3 LTS (64 bit). I read through all the older posts of people facing the same problem, and tried all the recommended steps. As a last ditch effort, i also tried to understand whether there was a problem with the symbolic links in my PC, which i couldn’t really grasp . I’m including the error in this post, any help would be greatly appreciated!

EXEC \<\<

See the file ‘configure.log’ for details. If this doesn’t help and you need  
further assistance, please post on the MRtrix3 community forum  
([http://community.mrtrix.org/](http://community.mrtrix.org/)), and make sure to include the full contents of  
the ‘configure.log’ file.

thankyou!

Hi @Abhi,

This sounds suspiciously similar to [this previous post](https://community.mrtrix.org/t/mrtrix3tissue-installation-error/7156/3)… Hopefully the instructions in that thread will help.

All the best,  
Donald
