automake-1.16: Objective C++ Support

 
 8.11 Objective C++ Support
 ==========================
 
 Automake includes some support for Objective C++.
 
    Any package including Objective C++ code must define the output
 variable ‘OBJCXX’ in ‘configure.ac’; the simplest way to do this is to
 use the ‘AC_PROG_OBJCXX’ macro (⇒Particular Program Checks
 (autoconf)Particular Programs.).
 
    A few additional variables are defined when an Objective C++ source
 file is seen:
 
 ‘OBJCXX’
      The name of the Objective C++ compiler.
 
 ‘OBJCXXFLAGS’
      Any flags to pass to the Objective C++ compiler.
 
 ‘AM_OBJCXXFLAGS’
      The maintainer’s variant of ‘OBJCXXFLAGS’.
 
 ‘OBJCXXCOMPILE’
      The command used to compile an Objective C++ source file.  The file
      name is appended to form the complete command line.
 
 ‘OBJCXXLINK’
      The command used to link an Objective C++ program.
