[This file is mirrored in both the FlightGear and SimGear packages.]
|
|
|
|
You *must* have OpenSceneGraph (OSG) installed to build this version of
|
|
FlightGear.
|
|
|
|
Notice that this version of SimGear/FlightGear requires at least OSG 3.0.0.
|
|
|
|
You can get the latest version of OSG from:
|
|
|
|
http://www.openscenegraph.org/
|
|
|
|
Build notes:
|
|
|
|
Unzip the file OpenSceneGraph-x.x.zip and install using the following
|
|
commands:
|
|
|
|
unzip OpenSceneGraph-x.x
|
|
cd OpenSceneGraph
|
|
ccmake .
|
|
|
|
[ While running ccmake: press 'c' to configure, press 'c' once more, and
|
|
then press 'g' to generate and exit ]
|
|
|
|
make
|
|
sudo make install
|
|
|
|
Also later release versions of OpenSceneGraph can be obtained by
|
|
svn, or you can use the OSG development svn 'trunk', but be warned,
|
|
OSG is always in heavy development, and at certain moments
|
|
in time, it may not compile completely, so, as usual, it is
|
|
recommended that you stay with released versions.
|
|
|
|
Installation notes:
|
|
|
|
In some unix/linux distributions, particularly 64-bit
|
|
systems, OSG may install its shared libraries in other than
|
|
/usr/lib, /usr/local/lib or $prefix/lib!
|
|
|
|
This does not seem to effect binary installation, which is
|
|
to $prefix/bin, nor header installation, which remains
|
|
$prefix/include. Just the shared libraries, and perhaps
|
|
only for 64-bit systems, or higher as, and when available.
|
|
|
|
The default is /usr/local/lib64 or $prefix/lib64 in
|
|
64-bit systems. This may cause problems with the auto-conf
|
|
tools when configuring and compiling FlighGear, since
|
|
even using the configure option --with-osg=$prefix
|
|
will not 'fix' the problem.
|
|
|
|
The are various ways to deal with this, which mainly depend
|
|
on whether you just want one version of OSG 'globally'
|
|
installed, or desire to be able to build, and run, FlightGear
|
|
against 'different' versions of OSG.
|
|
|
|
There is a parameter, -D LIB_POSTFIX= or -D LIB_POSTFIX=""
|
|
which can be passed to cmake OSG to force the OSG library
|
|
installation into the 'standard' "$prefix/lib".
|
|
|
|
OSG cmake advises of a post installation step -
|
|
$ sudo make install_ld_conf
|
|
which, if available, will add an openscenegraph.conf file
|
|
to the /etc/ld.so.conf.d folder, with the line -
|
|
${CMAKE_INSTALL_PREFIX}lib${LIB_POSTFIX}
|
|
and run 'ldconfig' to add this to the 'cache'. But this
|
|
option does not always seem available.
|
|
|
|
Configuring SimGear and Flightgear notes:
|
|
|
|
If you install OSG in other than the 'standard' directories,
|
|
you must add --with-osg=$prefix when configuring
|
|
SimGear and FlightGear. This will cause the auto-conf
|
|
tools to look in $prefix/include for headers, and
|
|
$prefix/lib for libraries, but _NOT_ in 'lib64'!
|
|
|
|
If the OSG is installed to a unique $prefix directory, then
|
|
it is also possible to make a 'link' entry lib -> lib64 to
|
|
get over this, but obviously this is not available if
|
|
$prefix/lib already exists, and contains entries.
|
|
|
|
Running fgfs, and others, with OSG shared libraries:
|
|
|
|
You must also deal with the executable loader being
|
|
able to find the OSG shared libraries when running fgfs,
|
|
and others, through perhaps using :-
|
|
$ export LD_LIBRARY_PATH=/path/to/osg/lib[64][:/other/paths]
|
|
or more permanently using a '.conf' file in the
|
|
/etc/ld.so.conf.d directory, and running
|
|
$ sudo ldconfig -v to update the 'cache'.
