5.10.6 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])
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_PROG_PATH 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])
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])
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_PROG_PATH 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])
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.
