current language did not change.
(AC_LANG_ASSERT): New.
(AC_PROG_CPP, AC_PROG_CXXCPP): Assert the language.
(_AC_PROG_F77_V, _AC_F77_NAME_MANGLING): Don't require
AC_PROG_F77, the code you include does it.
(AC_F77_LIBRARY_LDFLAGS): Set the language.
that `confestval' be read in binary mode. The shell then fails to
properly strip the rn.
Reported by Lars J. Aas.
* aclang.m4 (AC_LANG_INT_SAVE): Don't add any trailing new line,
and close the file.
Suggested by Peter Eisentraut.
* m4sugar.m4 (_m4_require): $2 defaults to $1.
Rename as...
(m4_require): this.
* acgeneral.m4 (_AC_REQUIRE): Remove, use m4_require if you want
to get into the gory details.
The main difference is that the former requires AC_LANG_COMPILER.
* aclang (AC_LANG_PREPROC, AC_LANG_PREPROC(C), AC_LANG_PREPROC(C++))
(AC_LANG_PREPROC(Fortran 77), AC_LANG_PREPROC_REQUIRE): New
macros. Issue a warning when looking for the Fortran 77
preprocessor instead of an error.
(AC_LANG_COMPILER): Check that it is run before the corresponding
AC_LANG_PREPROC.
(AC_PROG_C
(AC_LANG_COMPILER_REQUIRE): Don't call directly
AC_LANG_COMPILER(_AC_LANG), rather invoke AC_LANG_COMPILER so that
the generic code in AC_LANG_COMPILER is run.
(AC_REQUIRE_CPP): Use AC_LANG_PREPROC_REQUIRE.
(AC_PROG_CC, AC_PROG_CXX): Don't require being run before the
corresponding AC_LANG_PREPROC: AC_LANG_COMPILER does it.
Propagate AC_LANG_PREPROC_REQUIRE.
* acgeneral.m4 (AC_TRY_CPP, AC_EGREP_CPP): Use it instead of
AC_REQUIRE_CPP.
* acspecific.m4 (_AC_DECL_YYTEXT, AC_PATH_X): Don't
AC_REQUIRE_CPP, inner macro will do it.
* aclang.m4 (AC_PROG_GCC_TRADITIONAL, AC_C_STRINGIZE)
(AC_C_PROTOTYPES): Likewise.
(AC_C_STRINGIZE): Yeeks! The body of AC_CACHE_CHECK was not
quoted. Use @%:@ do assist Emacs.
For some reason (don't ask), this revamping revealed that
AC_PROG_CC_STDC, because of the `break', does not clean its tmp
files.
* aclang.m4 (AC_PROG_CC_STDC): Extract the creation of conftest.c
out of AC_COMPILE_IFELSE.
Be sure to clean the tmp files.
instead of hard coded `configure'.
* acgeneral.m4 (AC_COPYRIGHT): s/configure.in/__file__/.
(_AC_INIT_DEFAULTS_FDS): Append to AC_FD_LOG instead of creating
it. No longer insert the configure banner.
(_AC_INIT_DEFAULTS): Create config.log with the banner.
Define `as_me'.
(_AC_INIT_PARSE_ARGS, _AC_INIT_PREPARE, AC_MSG_NOTICE)
(AC_MSG_CHECKING, AC_MSG_RESULT, AC_MSG_RESULT_UNQUOTED)
(AC_MSG_WARN, AC_MSG_ERROR, AC_MSG_ERROR, AC_TRY_CPP)
(_AC_COMPILE_IFELSE, _AC_LINK_IFELSE, _AC_RUN_IFELSE)
(_AC_OUTPUT_FILES, _AC_OUTPUT_HEADERS, _AC_PROG_F77_V_OUTPUT): Use
`$as_me' instead of `configure'.
(AC_OUTPUT): Get rid of the UCA, and of the empty line when
dumping confdefs.h into config.log.
(_AC_OUTPUT_CONFIG_STATUS): Use _AC_INIT_DEFAULTS_FDS.
Print a banner.
Use AC_MSG_ERROR and AC_MSG_NOTICE.
* acgeneral.m4 (AC_CACHE_LOAD, _AC_OUTPUT_FILES, _AC_OUTPUT_LINKS)
(_AC_OUTPUT_HEADERS): Use AC_MSG_NOTICE.
* tests/semantics.at (missing templates): Adjust.
AC_INIT
AC_PROG_CC
AC_LANG_COMPILER_REQUIRE
AC_PROG_CC is expanded twice, because AC_PROG_CC provides
`AC_PROG_CC', and not `AC_LANG_COMPILER(C)' as expected by
AC_LANG_COMPILER_REQUIRE.
* aclang.m4 (AC_LANG_COMPILER(C)): Instead of calling AC_PROG_CC,
require it.
(AC_LANG_COMPILER(C++), AC_LANG_COMPILER(Fortran 77)): Likewise.
comments and empty lines.
Check that freezing produced no output.
* m4sugar.m4: Commentize what was not.
* m4sh.m4: Likewise.
* aclang.m4: Formatting changes.
Autoconf's file, do it afterwards, so that Autoconf promotes the
right use, but users still can use the old names.
Of course this revealed numerous non updated uses of old macros in
Autoconf's files. Adjust them.
But for the time being, keep `define' alive for Autoconf.
* acgeneral.m4 (_AC_DIVERT, AC_DIVERT, AC_DIVERT_PUSH)
(AC_DIVERT_POP): Move to...
* m4sugar.m4 (_m4_divert, m4_divert, m4_divert_push)
(m4_divert_pop): here.
* acgeneral.m4: Adjust to use only the M4sugar macros.
Nevertheless...
(AC_DIVERT_PUSH, AC_DIVERT_POP): New wrappers around the M4sugar
macros.
(_AC_DIVERT(...)): Rename all the diversions names as...
(_m4_divert(...)): these.
instead of reinventing the wheel. This also takes care of a bug
where the "-g" option was accepted if the compiler silently exits
with status unequal to 0.
(_AC_PROG_CXX_G): Likewise.
(AC_PROG_CC): As _AC_PROG_CC_G depends on $ac_objext and
$ac_exeext, move the expansion of _AC_OBJEXT and _AC_EXEEXT in
front of _AC_PROG_CC_G.
(AC_PROG_CXX, AC_PROG_F77): Likewise.
AC_LANG_COMPILER by the way of AC_COMPILE_IFELSE etc.
* acspecific.m4 (_AC_EXEEXT): Use _AC_LINK_IFELSE, not
AC_LINK_IFELSE to avoid AC_REQUIREing AC_PROG_CC which precisely
requires _AC_EXEEXT.
Don't run _AC_CYGWIN, _AC_MINGW32, _AC_EMXOS2.
* aclang.m4 (_AC_PROG_F77_G): Use _AC_COMPILE_IFELSE, not
AC_COMPILE_IFELSE.
(_AC_LANG_COMPILER_WORKS): Use _AC_LINK_IFELSE, not
AC_LINK_IFELSE.
* aclang.m4 (_AC_LANG_COMPILER_WORKS): Likewise.
* aclang.m4 (AC_PROG_CC_C_O, AC_PROG_F77_C_O): Fix typos where
$objext were used instead of $ac_objext.
from the output - it is only printed by Visual C that gives
correct exit status.
* aclang.m4 (AC_PROG_CPP): Don't try '${CC-cc} -nologo -E'
by the same reason.
and checks whether it produces errors or warnings. Don't put grep
output into a variable, use another grep instead.
(AC_TRY_CPP): Use _AC_TRY_CPP. Copy conftest.err to config.log
if the case of an error.
* aclang.m4 (AC_LANG(C), AC_LANG(C++), AC_LANG(Fortran 77)):
define AC_LANG_ABBREV to the short language name.
(_AC_PROG_CPP_WORKS): New macro. It checks whether the current
preprocessor can be used to check for existance of headers.
Most code taken from ...
(AC_PROG_CPP): ... here. Use _AC_PROG_CPP_WORKS. Use shell
"for" to find working CPP. Use AC_LANG_PUSH(C) and AC_LANG_POP -
it's a macro for C only.
(AC_PROG_CXXCPP): Rewritten using _AC_PROG_CPP_WORKS.
which uses $ac_objext hence depends upon _AC_OBJEXT.
* aclang.m4 (AC_PROG_CC, AC_PROG_CXX, AC_PROG_F77): Call
_AC_EXEEXT before _AC_OBJEXT since the former needs $ac_objext.
_AC_PROG_F77_GNU): Use ac_ext. Use ACEOF instead of EOF.
(AC_LANG_CONFTEST): New macro.
(_AC_PROG_CC_G, AC_PROG_CC_C_O, _AC_PROG_CXX_G, AC_PROG_F77_C_O,
_AC_PROG_F77_V_OUTPUT): Use it.
* acgeneral.m4 (AC_TRY_CPP, AC_EGREP_CPP, AC_COMPILE_IFELSE,
AC_LINK_IFELSE, AC_RUN_IFELSE): Likewise.
way of accessing Fortran name-mangling information other than
through CPP, and without having to know the different possible
name-mangling schemes.
* autoconf.texi: Documented AC_F77_FUNC
_AC_F77_NAME_MANGLING.
(_AC_F77_NAME_MANGLING): Use independent checks for the
name mangling of symbols with and without underscores.
Use algorithm with for loops instead of recursive macro calls.
(AC_F77_WRAPPERS): Adapt to changes in _AC_F77_NAME_MANGLING.
* doc/autoconf.texi (Fortran 77 Compiler Characteristics):
Remove documentation of AC_F77_NAME_MANGLING.
Remove documentation of f77_case and f77_underscore.
Replace AC_F77_FUNC_WRAPPER with AC_F77_WRAPPERS.
when detecting the verbose flag than when scanning for linker
options, and as a result the former test failed (under AIX/xlf).
* aclang.m4 (_AC_PROG_F77_V_OUTPUT): New macro to get the
output of linking an F77 program with a given verbose flag,
and preprocess it as required to scan for linker flags.
(_AC_PROG_F77_V): Use the above macro here...
(AC_F77_LIBRARY_LDFLAGS): ...and here, enforcing consistency.
leads to unnecessary warnings if both C and Fortran are checked.
(AC_PROG_F77_C_O): AC_REQUIRE AC_PROG_F77 instead of pretend you
need to be AC_BEFORE it.
causes the compiler to output verbose linking information.
(AC_F77_LIBRARY_LDFLAGS): Use _AC_PROG_F77_V instead of
simply "-v"
(AC_F77_LIBRARY_LDFLAGS): New algorithm to parse flags, uses
set/shift shell commands.
(AC_F77_LIBRARY_LDFLAGS): Set FLIBS at end, after determining
ac_cv_flibs.
