Rework of autoconfiscation infrastructure
Rework of autoconfiscation infrastructure
* autoconf/config.{guess,sub}: Update to GNU version 2003-10-07.
* autoconf/ltmain.sh: Update to GNU version 1.4.3.
* autoconf/autoconf: Remove (from now on we assume autoconf is
installed properly on the sytem).
* autoconf/autoconf.m4: Likewise.
* autoconf/autoconf.m4f: Likewise.
* autoconf/acgeneral.m4: Likewise.
* autoconf/acspecific.m4: Likewise.
* autoconf/aclocal.m4: Regenerate.
* autoconf/acinclude.m4: Remove (while moving the macros...)
* m4/gmp.m4: New file (...to here).
* Makefile.devel: Update to new scheme.
* configure.ac: Likewise.
* include/cln/GV_integer.h: Assume template specializations work.
* include/cln/GV_modinteger.h: Likewise.
* include/cln/config.h.in: Likewise, and drop HAVE_BOOL.
* src/base/cl_base_config.h.in: Drop support for obsolete ftime(3).
* src/base/random/cl_random_from.cc: Likewise.
* src/timing/cl_base_config.h.in: Likewise.

Usage: $0 [OPTION] ... [TEMPLATE-FILE] |
|
||||
|
|
||||
Generate a configuration script from a TEMPLATE-FILE if given, or |
|
||||
\`configure.ac' if present, or else \`configure.in'. Output is sent |
|
||||
to the standard output if TEMPLATE-FILE is given, else into |
|
||||
\`configure'. |
|
||||
|
|
||||
Operation modes: |
|
||||
-h, --help print this help, then exit |
|
||||
-V, --version print version number, then exit |
|
||||
-v, --verbose verbosely report processing |
|
||||
-d, --debug don't remove temporary files |
|
||||
-o, --output=FILE save output in FILE (stdout is the default) |
|
||||
-W, --warnings=CATEGORY report the warnings falling in CATEGORY [syntax] |
|
||||
|
|
||||
Warning categories include: |
|
||||
\`cross' cross compilation issues |
|
||||
\`obsolete' obsolete constructs |
|
||||
\`syntax' dubious syntactic constructs |
|
||||
\`all' all the warnings |
|
||||
\`no-CATEGORY' turn off the warnings on CATEGORY |
|
||||
\`none' turn off all the warnings |
|
||||
\`error' warnings are error |
|
||||
|
|
||||
The environment variable \`WARNINGS' is honored. |
|
||||
|
|
||||
Library directories: |
|
||||
-A, --autoconf-dir=ACDIR Autoconf's macro files location (rarely needed) |
|
||||
-l, --localdir=DIR location of the \`aclocal.m4' file |
|
||||
|
|
||||
Tracing: |
|
||||
-t, --trace=MACRO report the list of calls to MACRO |
|
||||
-i, --initialization also trace Autoconf's initialization process |
|
||||
|
|
||||
In tracing mode, no configuration script is created. |
