Hello,

I tried to install on macOS High Sierra with Homebrew, but got the following error after "make install" :

Error: The brew link step did not complete successfully The formula built, but is not symlinked into /usr/local Could not symlink share/cadabra2/images/cadabra2-gtk.png /usr/local/share/cadabra2/images is not writable.

Does anyone know what to do?

You can try that suggestion, but if that also fails, try brew doctor before you do anything else. That usually comes up with useful suggestions on broken installations.

Indeed sorry I should have mentioned that I had tried it right away but it repeats the complaint about this "images" folder. Brew doctor only mentions 2 missing symlinks:cadabra2 (obviously) and ghostscript. Do you think it may be related?

In any case, thank you very much for the very quick reaction!

You can try to make that /usr/local/share/cadabra2/images folder writeable?

I unsuccessfully tried "chmod +w /usr/local/share/cadabra2/images", so I still don't know what went wrong. Anyway I could build from source without any trouble, so no big deal.

Thank you very much again for your prompt reactions!

Maybe better to ask on the homebrew mailing list/forum.
