automake-1.16: C++ Support

 
 8.9 C++ Support
 ===============
 
 Automake includes full support for C++.
 
    Any package including C++ code must define the output variable ‘CXX’
 in ‘configure.ac’; the simplest way to do this is to use the
 ‘AC_PROG_CXX’ macro (⇒Particular Program Checks
 (autoconf)Particular Programs.).
 
    A few additional variables are defined when a C++ source file is
 seen:
 
 ‘CXX’
      The name of the C++ compiler.
 
 ‘CXXFLAGS’
      Any flags to pass to the C++ compiler.
 
 ‘AM_CXXFLAGS’
      The maintainer’s variant of ‘CXXFLAGS’.
 
 ‘CXXCOMPILE’
      The command used to compile a C++ source file.  The file name is
      appended to form the complete command line.
 
 ‘CXXLINK’
      The command used to link a C++ program.
