7.7 C++ and other languages

Automake includes full support for C++, and rudimentary support for other languages. Support for other languages will be improved based on demand.

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.

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.

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.
