This patch adds some more functionality to the header files and removes
*all* dependencies on SG_HAVE_NATIVE_SGI_COMPILERS in the SimGear code!
[dpm: I had to add some additional SG_USING_STD declarations to make
it compile]
- 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.
Initialise a "possibly uninitialised" variable (which was already
functionally correct).
[Note from DPM: this patch will be blown away if we ever update to a
newer version of Expat.]
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.
- changed return type of readXML from bool to void (uses an exception
to report problems now)
- removed XMLVisitor::error callback
- declared new readXML function that uses a path rather than a stream
- modified existing readXML function to take an optional path parameter
- implemented new readXML function with path instead of stream
- modified existing readXML function to use optional path parameter
- modified readXML to throw exceptions rather than returning a bool
value on error
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.
1. Fixed a bug reported by Curt for one of the getChild methods.
2. Cleaned up some of the error reporting, and require PropertyList as
the root element name. Also uncluttered the XML output a little
(removed type="unknown").
3. Added a new Long type (i.e. setLongValue, getLongValue, etc.), as
requested by Curt aeons ago.
4. Added aliases, so that a property's value can directly reflect the
value of another property.
5. Added a generalized inclusion facility, with parameters (panel
writers should love this one).
