File: autoconf.info, Node: Erlang Compiler and Interpreter, Next: Fortran Compiler, Prev: Objective C++ Compiler, Up: Compilers and Preprocessors 5.10.7 Erlang Compiler and Interpreter Characteristics ------------------------------------------------------ Autoconf defines the following macros for determining paths to the essential Erlang/OTP programs: -- Macro: AC_ERLANG_PATH_ERLC ([VALUE-IF-NOT-FOUND], [PATH = $PATH]) Determine an Erlang compiler to use. If ‘ERLC’ is not already set in the environment, check for ‘erlc’. Set output variable ‘ERLC’ to the complete path of the compiler command found. In addition, if ‘ERLCFLAGS’ is not set in the environment, set it to an empty value. The two optional arguments have the same meaning as the two last arguments of macro ‘AC_PATH_PROG’ for looking for the ‘erlc’ program. For example, to look for ‘erlc’ only in the ‘/usr/lib/erlang/bin’ directory: AC_ERLANG_PATH_ERLC([not found], [/usr/lib/erlang/bin]) -- Macro: AC_ERLANG_NEED_ERLC ([PATH = $PATH]) A simplified variant of the ‘AC_ERLANG_PATH_ERLC’ macro, that prints an error message and exits the ‘configure’ script if the ‘erlc’ program is not found. -- Macro: AC_ERLANG_PATH_ERL ([VALUE-IF-NOT-FOUND], [PATH = $PATH]) Determine an Erlang interpreter to use. If ‘ERL’ is not already set in the environment, check for ‘erl’. Set output variable ‘ERL’ to the complete path of the interpreter command found. The two optional arguments have the same meaning as the two last arguments of macro ‘AC_PATH_PROG’ for looking for the ‘erl’ program. For example, to look for ‘erl’ only in the ‘/usr/lib/erlang/bin’ directory: AC_ERLANG_PATH_ERL([not found], [/usr/lib/erlang/bin]) -- Macro: AC_ERLANG_NEED_ERL ([PATH = $PATH]) A simplified variant of the ‘AC_ERLANG_PATH_ERL’ macro, that prints an error message and exits the ‘configure’ script if the ‘erl’ program is not found.
