#44729: ImageMagick: Undefined symbols _crc32 _zlibVersion --------------------------+-------------------------- Reporter: jmhanly@… | Owner: ryandesign@… Type: defect | Status: new Priority: Normal | Milestone: Component: ports | Version: 2.3.1 Resolution: | Keywords: Port: ImageMagick | --------------------------+-------------------------- Comment (by ryandesign@…): Knowing what's in /usr/local/include and /usr/local/lib specifically might help. I suspect you may have a copy of zlib or libpng installed there that is interfering. Such interference is why we don't support having software installed in /usr/local while using MacPorts.
