Build issue on macOS with libiconv

[BusFactor1Inc]

macOS High Sierra fails to build any apps due to iconv linking issue in pngtool.

I have installed the latest libiconv from macPorts.

Don't know where your MacPorts is installed to, but if I assume it places things into /opt/local, try changing the configure script for pngtools to include --with-libiconv-prefix=/opt/local in either libraries/libgd/make.sh#L20 or in macosx/build-binary#L84. If that works we can see if we can patch this automatically?

Putting --with-libiconv-prefix=/opt/local in make.sh and adding "-L/opt/local/lib -liconv" to the build-binary allowed for a successful compile. Thanks for the pointers.

Funny thing is that i didn't have this problem on another machine using the same OS version. Odd.

It is something about having (or not having) macports in your path. Will need to look into this more next week to see how to patch, as I currently can't reproduce it.
