I use macOS Catalina, and installed EiffelStudio per instructions on the EiffelStudio install page. When I executed estudio
on the command line, I got this error
$ estudio
dyld: Library not loaded: /opt/local/lib/libgthread-2.0.0.dylib
Referenced from: /usr/local/Eiffel_19.05/studio/spec/macosx-x86-64/bin/estudio
Reason: image not found
Abort trap: 6
Could someone help me with a solution?
