Automake currently only includes full support for C, C++ (see C++ Support), Objective C (see Objective C Support), Objective C++ (see Objective C++ Support), Fortran 77 (see Fortran 77 Support), Fortran 9x (see Fortran 9x Support), and Java (see Compiling Java sources using gcj). There is only rudimentary support for other languages, support for which will be improved based on user demand.
Some limited support for adding your own languages is available via the suffix rule handling (see Handling new file extensions).
