User information about macOS Mojave

>> One specific change in Mojave is the deprecation of 32-bit software. Mojave can run existing 32-bit software but can't build 32-bit software anymore [3] so MacPorts can't offer 32-bit software on Mojave.

> Why is it not possible to build 32-bit software with a Macports version of gcc, linked against Macports version of libraries?

The 10.14 SDK doesn’t embed the 32-bit libraries anymore. I suppose if you compile clang/llvm from MacPorts, you can still continue to develop i386 software, though access to Cocoa would be problematic.
