Fortran 77 uses environment variables F77, FFLAGS, and FLIBS, # while Fortran uses FC, FCFLAGS, and FCLIBS. For each user-callable AC_* # macro, there is generally both an F77 and an FC version, where both versions # share the same _AC__FC_ backend. This backend macro requires that # the appropriate language be AC_LANG_PUSH'ed, and uses _AC_LANG_ABBREV and # _AC_LANG_PREFIX in order to name cache and environment variables, etc. ## ------------------- ## ## 0.

There is a # little mixture though of things actually handled by `configure', # such as running the `configure' in the sub directories. Minor # detail. # # There are two kinds of commands: # # COMMANDS: # # They are output into `config.status' via a quoted here doc. These # commands are always associated to a tag which the user can use to # tell `config.status' what are the commands she wants to run. # # INIT-CMDS: # # They are output via an unquoted here-doc.

This macro implements the # former task of AC_CHECK_TYPE, with one big difference though: AC_CHECK_TYPE # used to grep in the headers, which, BTW, led to many problems until the # extended regular expression was correct and did not give false positives. # It turned out there are even portability issues with egrep... # # The most obvious way to check for a TYPE is just to compile a variable # definition: # # TYPE my_var; # # (TYPE being the second parameter to the shell function, hence $[]2 in m4). # Unfortunately this does not work for const qualified types in C++, where # you need an initializer. So you think of # # TYPE my_var = (TYPE) 0; # # Unfortunately, again, this is not valid for some C++ classes. # # Then you look for another scheme. For instance you think of declaring # a function which uses a parameter of type TYPE: # # int foo (TYPE param); # # but of course you soon realize this does not make it with K&R # compilers. And by no means do you want to use this: # # int foo (param) # TYPE param # { ; } # # since C++ would complain loudly. # # Don't even think of using a function return type, since K&R cries # there too. So you start thinking of declaring a pointer to this TYPE: # # TYPE p; # # but you know fairly well that this is legal in C for aggregates which # are unknown (TYPE = struct does-not-exist). # # Then you think of using sizeof to make sure the TYPE is really # defined: # # sizeof (TYPE); # # That is great, but has one drawback: it succeeds when TYPE happens # to be a variable: you'd get the size of the variable's type. # Obviously, we must not accept a variable in place of a type name. # # So, to filter out the last possibility, we will require that this fail: # # sizeof ((TYPE)); # # This evokes a syntax error when TYPE is a type, but succeeds if TYPE # is actually a variable. # # Also note that we use # # if (sizeof (TYPE)) # # to `read' sizeof (to avoid warnings), while not depending on its type # (not necessarily size_t etc.). # # C++ disallows defining types inside `sizeof ()', but that's OK, # since we don't want to consider unnamed structs to be types for C++, # precisely because they don't work in cases like that. m4_define([_AC_CHECK_TYPE_NEW_BODY], [ AS_LINENO_PUSH([$[]1]) AC_CACHE_CHECK([for $[]2], [$[]3], [AS_VAR_SET([$[]3], [no]) AC_COMPILE_IFELSE( [AC_LANG_PROGRAM([$[]4], [if (sizeof ($[]2)) return 0;])], [AC_COMPILE_IFELSE( [AC_LANG_PROGRAM([$[]4], [if (sizeof (($[]2))) return 0;])], [], [AS_VAR_SET([$[]3], [yes])])])]) AS_LINENO_POP ])dnl # _AC_CHECK_TYPE_NEW(TYPE, # [ACTION-IF-FOUND], [ACTION-IF-NOT-FOUND], # [INCLUDES = DEFAULT-INCLUDES]) # ------------------------------------------------------------ # Check whether the type TYPE is supported by the system, maybe via the # the provided includes.
