8.10 Objective C Support

Automake includes some support for Objective C.

Any package including Objective C code must define the output variable OBJC in; the simplest way to do this is to use the AC_PROG_OBJC macro (see Particular Program Checks).

A few additional variables are defined when an Objective C source file is seen:

The name of the Objective C compiler.
Any flags to pass to the Objective C compiler.
The maintainer's variant of OBJCFLAGS.
The command used to actually compile an Objective C source file. The file name is appended to form the complete command line.
The command used to actually link an Objective C program.
