This repo contains my personal fork of MP-legacy-support with modifications suited to my own purposes.
You would be wise not to use this.
Three different libraries are provided
- libMacportsLegacySupport.a - A static library with the missing functions for the given OS.
- libMacportsLegacySupport.dylib - A dynamic library with the missing functions for the given OS.
- libMacportsLegacySystem.B.dylib - Similar to libMacportsLegacySupport.dylib but in addition re-exports the symbols from libSystem.B.dylib.
To use this library within MacPorts
add the legacysupport PortGroup to the Portfile. This will add the
required include paths and libraries to allow the library to do it's
magic with most build systems.
