automake-1.16: Objective C Support

 
 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 ‘configure.ac’; the simplest way to do this is to use
 the ‘AC_PROG_OBJC’ macro (⇒Particular Program Checks
 (autoconf)Particular Programs.).
 
    A few additional variables are defined when an Objective C source
 file is seen:
 
 ‘OBJC’
      The name of the Objective C compiler.
 
 ‘OBJCFLAGS’
      Any flags to pass to the Objective C compiler.
 
 ‘AM_OBJCFLAGS’
      The maintainer’s variant of ‘OBJCFLAGS’.
 
 ‘OBJCCOMPILE’
      The command used to compile an Objective C source file.  The file
      name is appended to form the complete command line.
 
 ‘OBJCLINK’
      The command used to link an Objective C program.
