build - Autoconf: Check if a program in an unsupported language compiles -


to conditionally enable part of autotooled project, need check whether short program stub in language not supported autotools out of box compiles or not.

i need ac_try_compile arbitrary compiler executable – create temporary file, write piece of code it, , try if invoking compiler (found via ac_check_progs before) returns exit code equal 0 or not.

what elegant/common way this?

ac_try_compile (which deprecated , replaced ac_compile_ifelse) supports limited set of languages: c, c++, fortran 77, fortran, erlang, objective c, objective c++ (source).

configure.ac can contain custom shell code - gets skipped on autoconf (really m4). why not write test in shell? if you're going use more 1 test, wrap in ac_defun.
