Pdftops error on MacBook Pro M1 #355

Closed abbiekressner closed 2 years ago

abbiekressner commented 2 years ago

I am trying to install export_fig on my MacBook Pro (Apple M1 Pro) without success. I have used export_fig for many years and really rely on it, so I hope this issue can be solved.

I receive the 'Pdftops error' when I try to save a figure as *.eps, and based on the suggestions, I have tried to follow the details in Issue #137. /usr/local/lib/libfreetype.6.dylib did not exist for me so instead I used the following.

sudo scp /opt/homebrew/Cellar/freetype/2.12.0/lib/libfreetyp
e.6.dylib /Applications/MATLAB_R2021b.app/bin/maci64/libfreetype.6.dylib

When I then try to open Matlab, I get the following error:

Caught "std::exception" Exception message is:

Have I done something wrong or is this related to the M1 architecture?

As far as I can tell, this is due to the fact that you are using an Intel-based Mac but the FreeType lib you're trying to use is based on the Arm64 architecture, which is incompatible. Try to reinstall pdftops from the Mac 64-bits download link here: https://www.xpdfreader.com/download.html (or just the FreeType lib from the link at the bottom of that page).
