9.8 C++ Support

Automake includes full support for C++.

Any package including C++ code must define the output variable `CXX' in `configure.in'; the simplest way to do this is to use the AC_PROG_CXX macro (see section `Particular Program Checks' in The Autoconf Manual).

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 actually compile a C++ source file. The file name is appended to form the complete command line.

CXXLINK
The command used to actually link a C++ program.
