This change is the logical counterpart of SimGear's change from commit
79f869a7f32910197be72b21f6489fbbba02c836 that moved the following files
from simgear/misc to simgear/io/iostreams:
gzcontainerfile.cxx
gzcontainerfile.hxx
gzfstream.cxx (formerly zfstream.cxx)
gzfstream.hxx (formerly zfstream.hxx)
sgstream.cxx
sgstream.hxx
sgstream_test.cxx
The mirror protocol now sends the position for internal as well as
leaf nodes, and the group uses this data to sort when no explicit
Z-indices exist. This gets the extra-500 much closer to working!
Requires FGData commit: 0565eaab10a5d466cd485766b17d1870936a0a57
(which actually renames the file).
Also disables the preferences-load command since I don’t believe it
would actually be safe to reload the defaults without doing a simulator
reset (aircraft -set.xml values would be overwritten, for example)
1. The variables SIMGEAR_CORE_LIBRARIES and
SIMGEAR_CORE_LIBRARY_DEPENDENCIES are
no longer set... hence the need to hard-code 'SimGearCore'
in the target_link_libraries()
2. And -lfreetype means the linker must know the specific
link path to it, while the variable FREETYPE_LIBRARIES
contains the fully qualified path to the library.
3. Improved the 'found glut' message to show exactly what
was found, and being used... This is due to the user possibly
also have the near binary compatible glut32.lib found, which
will fail in the link due to some freeglut extensions have been
used.
4. Adding the define -DFREEGLUT_LIB_PRAGMAS=0 is
necessary to stop the freeglut headers from using a MSVC pragma
to declare the library, which will /not/ not be found...
5. In Windows the glew library is not -lGLEW, and even if it
was, it would not be found, without adding a link_directories(
path/to/library ),
while the GLEW_LIBRARIES variable has the fully qualified path.
Add option --print-solidness
without this option, behaviour of fgelev is unchanged
with this option the word "solid" gets printed behind the elevation if the
material at the given location is solid. A hyphen (-) gets printed otherwise
Remove uses of .str(), .c_str() and some other methods of SGPath.
Pass SGPath directly where possible, or explicitly convert to the
appropriate 8-bit encoding.
