Not sure! I tried converting some heic images now and it worked fine for me on
macOS 10.13.6.
What's the contents of
/opt/local/lib/ImageMagick-6.9.11/modules-Q16/coders/heic.la?
Does /opt/local/lib/ImageMagick-6.9.11/modules-Q16/coders/heic.so also exist?
What's the output of:
otool -L /opt/local/lib/ImageMagick-6.9.11/modules-Q16/coders/heic.so
What OS version are you on? You mentioned /opt/local/lib/libheif.la exists. The
default behavior for MacPorts is to delete .la files* on OS X 10.9 and later.
If you are on 10.8 or earlier, maybe there is a problem specific to older OS
versions that we need to investigate. The only reason why you should have
/opt/local/lib/libheif.la if you're on 10.9 or later is if you edited
macports.conf and set "delete_la_files no".
*ImageMagick is an exception. It needs the .la files of its modules for proper
operation so they will not be deleted for that port on any OS version.
