If you ran into this problem when you tried to run some .mexmaci files, here is how you fix the error.
A user tried to use a Matlab toolbox which uses some .mexmaci files. Part of the error mesage is ‘/usr/local/lib/libgfortran.3.dylib’ (no such file). This is because the .mexmaci was compiled using libgfortran.3.dylib and the file is not on the machine. This file is part of [email protected] on Homebrew. In order to fix this problem, we need to install Homebrew and use Homebrew to install [email protected] Note that this only applies to Intel Mac. If you have the the new Apple Silicon Mac, you are out of luck.
- Install Homebrew if you don’t have it already. Open a Terminal window and type
/bin/bash -c "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/HEAD/install.sh)"
- Follow the instructions to finish the installation of Homebrew. You might need to type some commands to add Homebrew to your PATH variable.
- Install gcc
brew install [email protected]
- Create a symbolic link
sudo ln -s /usr/local/Cellar/[email protected]/6.5.0_7/lib/gcc/6/libgfortran.3.dylib /usr/local/lib/libgfortran.3.dylib
Now you are ready to try to run that .mexmaci files again.
