(alflags.sed): New sub sed program.
Compute the flags of aclocal from Makefile.am instead of
Makefile.in, it is unlikely that aclocal be used but not automake,
while it is convenient to be able to run autoreconf even if
automake was not run yet.
Use `autoconf --trace' to get the list of configuration headers.
* tests/base.m4 (m4_wrap, AC_REQUIRE, AC_SHELL_MKDIR_P): Use it.
* autoconf.sh: Properly handle the case where `$output' is `-'
(i.e., stdout).
Handle `-ofile', not only `-o file'.
* doc/autoconf.texi: Free Franc,ois Pinard from iftex and ifinfo,
use @,c.
Don't use `@code{m4}' when you mean M4, just as you shall not say
`@code{cc}' when you refer to the C language.
in a messy state. Don't even try to emulate AC_REQUIRE: just
introduce a diversion just for AC_REVISION, and let the magic
happen.
Fixes Autoconf PR/134, from Raja R Harinath.
* acgeneral.m4 (_AC_DIVERT(REVISION)): New diversion.
(AC_REVISION): Don't require AC_INIT, dump in your diversion.
(_AC_INIT): Delete, inline its body in...
(AC_INIT): here.
(_AC_INIT_NOTICE, _AC_INIT_COPYRIGHT): New macros so that...
(AC_INIT): be more uniform.
(AC_INIT, AC_REVISION, AC_COPYRIGHT): `define', don't AC_DEFUN.
compiler needs it, it is likely to be required when linking C/C++
with Fortran.
<-YP,*>: Fix the list of arguments to loop on.
Don't mess with the user variable name space.
<ac_ld_run_path>: Prepend LD_RUN_PATH directories with -R only
when running Solaris (without this, link errors occur).
warning message printed when only --host is given. Fix printing
of multiple compiler cache values, use PATH argument.
* aclang.m4 (AC_LANG_COMPILER_WORKS): Print the cross compile
status, fix problem where two results were printed at once.
lf95 (Lahey/Fujitsu Fortran) and pgf77 (Portland Group Fortran)
(_AC_PROG_F77_G): Some Fortran compilers produce stdout/stderr
output even if no errors occur - check exit status rather than
output.
* acgeneral.m4 (build_alias): Set to host_alias if --build is not
given but --host is, and enable cross-compile auto-detection. If
both are, and are different, enable cross compilation.
(AC_CANONICAL_HOST): Adjust help message.
(cross_compiling): Enclose in quotes when testing.
* aclang.m4 (_AC_LANG_COMPILER_WORKS): If cross_compiling is
maybe, set it to yes or no depending on the result of the
execution test.
* doc/autoconf.texi: Document the change.
* doc/install.texi: Likewise.
$AUTOMAKE and $ACLOCAL.
Pass --verbose to the tools.
Avoid using plenty of variables, just append to existing
variables.
* doc/autoconf.texi: List options in the order --help, --version,
--verbose, --debug, and then specific options.
(Specifying Names): When describing the system triplets, use the
same names as the shell variables.
(System Type Variables): Delete, merge its content into...
(Canonicalizing): here.
Clarify the difference between the `foo_target' and `foo'
variables.
AC_CONFIG_COMMANDS, AC_CONFIG_FILES): Use a shell variable instead
of an m4 variable to store what must be done, so that sh
conditionals are honored.
(_AC_OUTPUT_LINKS, _AC_OUTPUT_HEADERS,
_AC_OUTPUT_COMMANDS, _AC_OUTPUT_FILES): Adjust.
* tests/semantics.m4: Test the four AC_CONFIG sisters.
* doc/autoconf.texi (Configuration Actions): Promote the use of
literals, show it works properly with sh conditionals.
| AC_DEFUN([TEST1], [REQUIRE([TEST2a])REQUIRE([TEST2b])])
| AC_DEFUN([TEST2a], [])
| AC_DEFUN([TEST2b], [REQUIRE([TEST3])])
| AC_DEFUN([TEST3], [REQUIRE([TEST2a])])
|
| AC_INIT
| TEST1
because it produces TEST3; TEST2a; TEST2b; TEST1.
Fix this bug, implement the solution provided by Axel Thimm,
and test AC_REQUIRE.
* acgeneral.m4: Document this implementation.
(_AC_DEFUN_PRO, _AC_DEFUN_EPI, AC_REQUIRE): Be sure that macros
are emitted in the same order as they are expanded.
(AC_REQUIRE): Forbid being calling out of an AC_DEFUN'd macro (in
particular the top level).
* tests/base.m4 (AC_REQUIRE): New test.
* acgeneral.m4 (AC_PRO, AC_EPI): Rename as _AC_DEFUN_PRO and
_AC_DEFUN_EPI.
Adjust dependencies.
(AC_DEFUN): Remove the not-to-be-released specializing mechanism.
(AC_SPECIALIZE): Remove for the same reasons.
Adjust dependencies.
(_AC_INIT_DEFAULTS, _AC_INIT_PARSE_ARGS, _AC_INIT_VERSION,
_AC_INIT_PREPARE, _AC_CANONICAL_SPLIT, _AC_CHECK_TYPE_NEW,
_AC_CHECK_TYPE_OLD): Define via `define' instead of `AC_DEFUN':
they are not related to AC_REQUIRE in any way.
* acspecific.m4 (AC_PROG_ECHO, _AC_DECL_YYTEXT, _AC_PATH_X_XMKMF,
_AC_PATH_X_DIRECT): Define via `define' instead of `AC_DEFUN'.
avoid cache variable conflicts between AC_CHECK_PROG invocations.
(AC_PATH_TOOL): Fix same bugs as in 6/9/00 fixes to AC_CHECK_TOOL.
Pass correct arguments to AC_CHECK_PATH (different from
AC_CHECK_PROG). Use AC_CHECK_PATH cache variable, not
AC_CHECK_PROG var, and use two variables for two invocations as
above. Quote AC_CHECK_* args.
