- Removed some old cruft.
- Removed some support for older versions of automake which technically was
correct, but caused the newer automakes to squawk warnings during an
initial sanity check (which isn't done very intelligently.)
NOTE: this fix is technically not correct for older version of automake.
These older version use the variable "INCLUDES" internally and could have
them already set to an important value. That is why we were appending
our values to them. However, newer versions of automake don't set this
value themselves so it is an error to append to a non-existant variable.
We seem to "get away" with overwriting the value on older versions of
automake, but if you have problems, consider upgrading to at least
automake-1.5.
are things that are needed, but that many systems already have packages
available to install, and many users may have versions of these already
installed to support other projects. So rather than build and install by
default with the main SimGear build/install, these are kept separate so that
those users that don't have them already installed can build and install
them separately.
developer will need to build and install these separately if they
don't have packages already installed by their system. See
README.metakit and README.zlib for more details.
As a convenience, pristine tarballs of the metakit and zlib source
code trees are included with the simgear distribution (and cvs.)
- automake-1.4 sets default values for INCLUDES which we can't
overwrite.
- automake-1.5 renames this to DEFAULT_INCLUDES and leaves INCLUDES
open for the developer to use.
Thus for automake-1.4 we are forced to 'append' to INCLUDES and in
automake-1.5 we can just set the value to whatever we like.
Unfortunately, the behaviors of the two versions are mutually
incompatible.
The solution I am committing now works for both versions but
automake-1.5 generates a lot of spurious warning messages that are
annoying, but not fatal.
flightgear, especially when this occurs in a simgear .hxx file. This is
now expressly forbidden, and will cause problems anyways because we now
changed the name to <simgear_config.h> which isn't installed, so you can't
include it in an installed header file.
mutex that unlocks the mutex when the SGGuard object goes out of scope.
The SGxxxQueue<T> template family factor out the common behaviour we
need for passing data between threads.
Added '--with-cxx=COMPILER[:flags]' to ./configure in order to set the
compiler and flags. If this option is omitted then the default compiler
is assumed (ie the current behaviour). This duplicates the effect of
passing CC, CFLAGS, CXX and CXXFLAGS on the command line to configure
and make.
