is an example). This can happen in circumstances that are not
manageable by the OSG itself (e.g. 3rd party buggy program) but one
would expect the plugin to be able to recover by returning
ReadResult::ERROR_IN_READING_FILE.
libpng provides two callbacks for warnings and errors - those are
currently unused. By default, they point to function that call exit()
or something similar (the default error callback never returns). This
patch registers the callbacks using libpng's mechanisms, makes the
warning callback emit an osg::notify(osg::WARN) message and the error
callback throw an error. The reading process is enclosed in a
try...catch block. Upon error, the memory is freed and
ReadResult::ERROR_IN_READING_FILE is returned.

completed the new registration of the plugin-readerwriters
("REGISTER_OSGPLUGIN") according to your osgstaticviewer-example (see
attachment, based on today's svn)."
It should not be introusive to any other palatform apart MSVC, but in order to link to debug-specific libs
I had to change plugins CMakeLists to differentiate debug/release linkage, I have used the same macro used in core libs
Now the macro used for plugin and examples linking test for existance of TARGET_LIBRARIES_VARS
that holds the names of the variables that have to be used for linking"
instead of osgDB::Registry where it original lay. This has been done to allow
fileName strings to be encode data rather than just file names, such as one
requires when using PagedLOD along with plugins for doing dynamic tesselation.
2) Changed Makedepend system to make individual dependency files, which
should save time rebuilding dependencies by limiting the regeneration
of dependency file for only modified source files.
osg::Image::setImage has also been modified to require the AllocationMode
mode to be passed to it so that it knows how to delete the data once the
image goes out of scope.
Port the image plugins across to specify the new AllocationMode, and converted
them across to using new/delete in place of malloc/free.
added since the png loader itself doesn't not seem robust enough at detecting
non png files.
Added a tab in to the flt code to make it more obvious what is happening in
the flow of the code.
library and plugin files that looked like system library and system files
which would have deleted original files on a 'make install'. Cygwin is not
tested yet, but this needed to get fixed before a cygwin user wiped out his
system library files.
Added distrules and makerpms for building RPM distributions
Removed old RedHatRPM distribution build directory
Added new dist/RPM directory and placed temporary .spec files (these
are generated by Make/makerpms and are not intended for stand-alone
use, but they keep the directory warm and CVS happy)
added prefixes and suffixes to libs and plugins. ALl this to accomodate
cygwin...
Also added INST_SYS_PREFIX and INST_SHARE_PREFIX for installation, as well
as "standardizing" the install locations for the various platforms.
the Make directory is left with four files only :
makedefs
makerules
makedirrules
instrules
These work for all platforms supported so far, which include :
Linux
Irix
Solaris
MacOSX
Cygwin
FreeBSD
plugin names hanging around despite being deprecated. These definiations
confused the make install/make instclean so it tried to link a non existant
library. Have removed old definitions and everything intalls properly once
more:-)
for settings options in osgDB::Registry, and added the paramter to all of the
reaader/writer plugins. The Options structure by default has an string attached
for packing basic options, however, it also can be subclassed to encapsulate
any users defined option data. In the later case both the client code *and*
the plugin need to be aware of subclass, the plugin will need to use
dynamic_cast<> to assertain its type.
