This also includes Bison version check. Versions before 3.0 don't
support them in a reliable way and we don't promise to work with
versions older than 2.4.
Make indentation and quotation consistent in configure macros.
Also remove --with-sysinclude option, which was broken for 7 years
and nobody complained.
Thanks to Ruben Kerkhof for source patches.
The patch allows to use autoreconf, replaces some long obsolete
constructs and does some other minor cleanups. Also, the file
configure.in is renamed to configure.ac, as the old name has been
deprecated for a long time.
Thanks to Ruben Kerkhof for the patchset.
Adds two new default GCC options related to optimizations
(-fno-strict-aliasing and -fno-strict-overflow). This
should fix some hyperaggressive GCC optimizations.
Also updates autoconf option detection.
operations on 2.1/2.2 kernels. This allows passing of real interface
indexes instead of referencing interfaces by their IP addresses which
fails badly in presence of unnumbered interfaces.
Unfortunately, this structure is not visible with glibc 2.0 as it provides
its own networking headers :-( Both libc5 and glibc 2.1 should be OK.
guesses most system-dependent parameters and determines name of system
configuration file (sysdep/cf/...) with the remaining ones.
To compile BIRD, you now need to do:
autoconf # Create configure from configure.in
./configure # Run configure script
make # Compile everything
Configuration files:
sysdep/config.h Master config file
sysdep/autoconf.h Parameters determined by configure script
sysdep/cf/*.h Fixed system configuration we're unable
to guess.
Makefiles are still the original ones, but this will change soon.
