-\r
-\r
-SECTION ONE : Distribution Questions\r
-\r
-1.1) Where can I get the latest version of this FAQ ?\r
-\r
-Ans: The latest version is stored at\r
- http://www.online-club.de/home/olk/progs/flightgear\r
- and it's updates are announced at flightgear mailing lists.\r
-\r
-------------------------------------------------------------------------\r
-1.2) What else is a must read ?\r
-\r
-Ans: Please also check out the "Getting started"-document which \r
- provides much, much detailed information.\r
-\r
-------------------------------------------------------------------------\r
-1.3) Where is the latest distribution of Flight Gear... ?\r
-\r
-Ans: ftp://ftp.flightgear.org/pub/fgfs/Source\r
-\r
-------------------------------------------------------------------------\r
-1.4) Where can I find the newest snapshots ?\r
-\r
-Ans: ftp://ftp.flightgear.org/pub/fgfs/Source/Snapshots\r
-\r
-------------------------------------------------------------------------\r
-1.5) Where can I fly ?\r
-\r
-Ans: In front of your monitor, hehehe...\r
- \r
-[FG until v0.58]:\r
- Curt has a nice collection of some flight-scenarios in the U.S.\r
- have a look at the descriptions and needed files \r
- http://www.flightgear.org/Places/\r
- \r
- There are also scenarios located at:\r
- ftp://ftp.flightgear.org/pub/fgfs/Scenery/\r
- There you find currently AZ-central, Equador, Spain, Munich (DE)\r
- \r
- Frankfurt (DE) can be found at\r
- http://people.frankfurt.netsurf.de/teddy/frankfurt.tar.gz\r
- \r
- Switzerland scenario at\r
- http://www.2sic.ch/Hoshy/flightgear.html\r
- \r
-[FG after v0.59 incl.]:\r
- Due to changes to the scenery format, which is currently v0.2, \r
- the old Scenery Files (see above) are not compatible to FlightGear\r
- v0.59 and later.\r
-\r
- The folowing Scenery Files are recommended instead:\r
- \r
- Alaska (Prince William Sounds) Scenario located at\r
- ftp://ftp.flightgear.org/pub/fgfs/Scenery/new-format-demo.tar.gz\r
- \r
- You also need the fgfs-base-0.59.tar.gz package with new graphics\r
- ftp://ftp.flightgear.org/pub/fgfs/Shared\r
- \r
-------------------------------------------------------------------------\r
-\r
-========================================================================\r
-\r
-SECTION TWO : Compiling questions\r
- For the time beeing more Unix/Linux related.\r
-\r
-\r
-2.1) Flight Gear doesn't smooth compile though configured succesful\r
-\r
-Ans: The fgfs-sources contain some Scenery Tool Kits beeing yet beta,\r
- they use libraries written by others so there is often some\r
- code/makefile tweaking needed. But this doesn't matter since\r
- the Flight Gear executable is then already compiled. \r
- Just make install from toplevel Makefile directory \r
- and up you go...\r
-\r
------------------------------------------------------------------------\r
-2.2) "gpc.o" and "gpc.h"\r
- Can anyone advise me on what to do with the gpc.c and gpc.h files. \r
- I retrieved them OK after "configure"reported that they were needed. \r
- But, I don't know what I'm supposed to do with them.\r
-\r
-Ans: Flight Gear's Makefile expects libgpc to be on your System.\r
- Try this: gcc -c gpc.c\r
- ar cru libgpc.a gpc.o\r
- Then copy libgpc.a to some place that your compiler knows about such\r
- as /usr/local/lib, and then try compiling again. A better idea would be\r
- to set LIBRARY_PATH to point to the location where you installed \r
- the libgpc.a file instead of dropping it into a system-wide library \r
- directory.\r
- \r
- Caveat Emptor: \r
- One word of warning to Linux / Unix users. I recently discovered \r
- that the gnu pascal compiler is also called "gpc" and comes with a \r
- libgpc.a I know this has caused confusion on the part of at least one\r
- or two people.\r
-\r
--------------------------------------------------------------------------\r
-2.3) compiler could not find gfc/...\r
- \r
-e.g. main.cxx:32: gfc/gshapefile.h: No such file or directory\r
- main.cxx:30: gfc/gadt_polygon.h: No such file or directory\r
- main.cxx:31: gfc/gdbf.h: No such file or directory\r
- main.cxx:32: gfc/gshapefile.h: No such file or directory\r
- there is no gadt_polygon.h on my system. What library does it belong to ?\r
-\r
-Ans: This is part of the GFC library it is not needed to run FlightGear\r
- as it is part of the beta Scenery Tool Kit\r
- GFC -- Geographic Foundation Classes library\r
- http://www.geog.psu.edu/~qian/gfc/index.html\r
-\r
---------------------------------------------------------------------------\r
-2.4) Red Had 5.1/5.2 related problems\r
-\r
-I quickly ran into problems with the basic_string library. (see undefined ref.)\r
-\r
- c++ -g -O2 -L/usr/local/lib -L/usr/X11R6/lib -o testbucket\r
- testbucket.o../../Lib/Bucket/libBucket.a -lmtestbucket.o: In function\r
- FGBucket::gen_base_path(void)':/usr/include/g++/std/bastring.h:75: undefined\r
- reference to Basic_string<char,string_char_traits<char>,\r
- __default_alloc_template<true, 0>>::Rep::clone(void)'collect2: ld returned 1 \r
- exit statusmake[2]: *** [testbucket] Error 1\r
-\r
-\r
-Ans: I ran into the same problem on my RedHat 5.2 system (brand new). \r
- After some searching I found out that it's got to do with a 'bug' in \r
- the stdlibc++libraries. I picked up libstdc++-2.9.0-2.i386.rpm, \r
- installed it and FGFS compiled just fine (after some other problems \r
- with gfc, I had to pick up the one from the fgfs site). However, some \r
- other packages must have the libstdc++-2.8 libraries....\r
-\r
-Ans: I also solved it with the 2.8 libraries by including \r
- /usr/include/g++/std/bastring.cc into the example programs. \r
- I believe this can be done since it's a template. \r

-\r
-SECTION THREE : User Questions\r
-\r
-\r
-3.1) Upside down after crash ?\r
- After beeing crashed on the ground the navion continues to fly\r
- upside-down and it stucks at almost groundlevel,\r
- (like cruse missile ;-) flying with a reverse heading as before\r
- and "balancing" left and right. The only solution seems to be\r
- to give full throttle and then at +80-90 kts it can move up by\r
- pressing one of the "elevator arrows" like a rocket doing a loop.\r
- But hey, that's nerving bc the loop is allways to short and the\r
- responding time of navion (correcting the "roll") is also to short,\r
- which results in crash so you have to re-throttle again.\r
-\r
-\r
-Ans: In his infinite wisdom the FlightGear GrandMaster decided \r
- that planes were to valuable to allow them to be destroyed\r
- by novice pilots who seemed to crash alot.\r
-\r
- The result of this as you have noticed is that\r
- with a little practice an ingenuity you can trim the ship \r
- to fly inverted along the ground.\r
-\r
- The trick to learn is to roll back to normal (non inverted)\r
- do this by nursing the elevator to get to about 500 feet or so\r
- and use the aierlons to snap roll 180*.\r
-\r
- This is all good avionics except for the plane not destroying itself. \r
-\r
- Remember the controls work in reverse when you are inverted\r
- and keep that airspeed up !!!\r
-\r
----------------------------------------------------------------------------\r
-3.2) Ailleron vs Rudder\r
- What's the difference. Both help the plane to turn, that i did understand\r
-\r
-Ans: There is a bit of info on aileron vs. rudder here:\r
- http://www.arundel.net/xplane/html/crosswind.html\r
- http://www.monmouth.com/~jsd/how/\r
-\r
----------------------------------------------------------------------------\r
-3) FG is sooo slow (1 fps), though i got hardware acceleration like\r
- Voodoo/Voodoo2 etc... What's the reason ?\r
-\r
-Ans: Flight Gear supports hardware acceleration, but it seems not\r
- to be activated. Even a P-400 goes berzerk using software rendering.\r
- First check out if you have MESA with glide support.\r
- Linux Users enter "make linux-glide" to compile Mesa\r
- \r
- Check out your environment variables, whether you use soft or hard-ware\r
- rendering. Here an example that should work :\r
- \r
- You have to tell Mesa to use fullscreen\r
- \r
- MESA_GLX_FX=fullscreen\r
- \r
- You also must set the appropriate Voodoo vars, here is for Voodoo2\r
- the Voodoo1 vars may slightly differ.\r
- \r
- SSTV2_BGAMMA=1.00\r
- SSTV2_FASTMEM_RAS_READS=1\r
- SSTV2_FASTPCIRD=1\r
- SSTV2_GAMMA=1.00\r
- SSTV2_GGAMMA=1.00\r
- SSTV2_GRXCLK=95\r
- SSTV2_RGAMMA=1.00\r
- SSTV2_SCREENREFRESH=60\r
- SSTV2_SWAP_EN_WAIT_ON_VSYNC=0\r
- SSTV2_VGA_PASS=0 \r
- \r
- The Voodoo vars can be obtained at:\r
- http://www.bahnhof.se/~engstrom/e_3dfxvars.htm\r
- \r
- Another good tool is glide-control to set the env. vars, go get it at:\r
- http://www.ling.ed.ac.uk/~oliphant/gc \r
- \r
- Check also the help-startup-screen of Flight Gear:\r
- fgfs --help\r

+ <p>Well, that depends. First make sure you are using the appropriate

+ <p>The FlightGear <i>Downloads</i> page
+ (<a href="http://flightgear.org/Downloads/">http://flightgear.org/Downloads/</a>)
+ should tell you what versions you need if you are trying to compile
+ the latest stable release. If you are using a development snapshot,
+ make sure all three packages are up-to-date.</p>
+ <p>Also ensure that you have some implementation of OpenGL with glut
+ support with the appropriate header files. Linux users with nVidia
+ cards should make sure you have the latest drivers from nVidia. Other
+ Linux users make sure you have Mesa3D
+ (<a href="http://mesa3d.org">http://mesa3d.org</a>)
+ and your X server installed correctly. Windows users see
+ <a href="http://www.x-plane.com/SYSREQ/v5ibm.htm">http://www.x-plane.com/SYSREQ/v5ibm.html</a>,

+ <u>Why is FlightGear so slow?</u></a></b>
+ <div class="indent">
+ <p>FlightGear supports hardware acceleration, but it seems not to be
+ activated. Make sure you have OpenGL libraries installed and
+ configured properly and make sure you have the latest drivers for your
+ video card.</p>
+ <p><b>Linux users</b>: If you are an nVidia user, follow their
+ directions on getting your card working. For most other users, make
+ sure Mesa is installed property and ensure that you have the
+ appropriate kernel device drivers for your card. Most people (and
+ distributions) use modules for their video card device drivers; run
+ <i>`lsmod`</i> as root to see what modules are loaded. You should also
+ make sure that you are loading the appropriate modules in your
+ XF86Config and that your video device section is correct. Now try
+ running an OpenGL application (other than FlightGear) to see how it
+ performs. You can try the <i>gears</i> demo from Mesa or something

+ </div>
+
+ <b><a name="5.2">5.2 -
+ <u>Why is my SGI machine so slow?</u></a></b>
+ <div class="indent">
+ <p>First of all, one of the most common mistakes on SGI hardware is to
+ forget to specify --fog-fastest. On most SGI machines the EXP2 shading
+ model isn't hardware supported resulting in frame rates below 1 frame
+ per second (fps).</p>
+ <p>FlightGear makes extensive use of the OpenGL z-buffer feature,which
+ on most older SGI hardware is only supported in software. This means
+ that the CPU has to do all the z-buffer calculations in addition to the
+ other tasks FlightGear involves (flight dynamics, scenery tracking,
+ pushing commands into the graphics queue, etc). The following features
+ are software rendered on low-end SGI machines (like Indy and
+ Indigo):</p>
+ <ul>
+ <li>stencil and accumulation buffer</li>
+ <li>depth queuing and depth buffering</li>
+ <li>fogging, lighting, clipping and transforms</li>
+ <li>texturing</li>
+ </ul>
+ <p>This means that running FlightGear with the following options may not
+ even get the desired result:</p>
+ <p><code>./runfgfs --fog-disable --shading-flat --disable-skyblend \</code><br>
+ <code>--disable-textures --disable-clouds --disable-sound \</code><br>
+ <code>--disable-panel --enable-hud --disable-anti-alias-hud</code></p>
+ <p>I could even imagine that adding --enable-wireframe doesn't work on
+ these machines (I would be happy to be proven wrong though).</p>
+ <p>On a machine like O2 the following options give an acceptable
+ result:</p>
+ <code>./runfgfs --fog-fastest --disable-sound</code>
+ <p>Since I don't have access to other SGI hardware I can't tell which
+ options would be appropriate for your situation.</p>
+ </div>
+
+ <b><a name="5.3">5.3 -
+ <u>Stuck upside down after "crash"?</u></a></b>
+ <div class="indent">
+ <p>In his infinite wisdom the FlightGear Grand Master decided that
+ planes were to valuable to allow them to be destroyed by novice pilots
+ who seemed to crash a lot. The fact that nobody has bothered to model
+ crashes may have something to do with it too. :-)</p>
+ <p>The result of this as you have noticed is that with a little
+ practice an ingenuity you can trim the ship to fly inverted along the
+ ground.</p>
+ <p>The quick answer is to hit Ctrl+U (with the default key bindings)
+ to warp the plane up 1000ft.</p>
+ <p>For the stubborn people out there: The trick to learn is to roll
+ back to normal (non inverted) do this by nursing the elevator to get
+ to about 500 feet or so and use the ailerons to snap roll 180*.
+ This is all good avionics except for the plane not destroying
+ itself. Remember the controls work in reverse when you are inverted
+ and keep that airspeed up!!!</p>

+ <u>Why doesn't audio work properly under Irix?</u></a></b>
+ <div class="indent">
+ <p>FlightGear (as of June 2001) uses the Portable Libraries (PLIB)
+ for playing audio. The audio queue implementation of PLIB is far from
+ optimal (in fact it's just wrong). This seems to work on other
+ platforms quite well, but Irix expects things to be programmed
+ properly.</p>
+ <p>There has been discussion about using OpenAL
+ (<a href="http://www.openal.org">http://www.openal.org</a>)
+ for the next release of both PLIB and FlightGear. Tests show that
+ the OpenAL audio implementation does the job right, meaning that
+ these audio problems should be gone by then. In the mean time it is
+ best to disable audio on Irix completely (by adding --disable-sound
+ either on the command line or to your <code>$HOME/.fgfsrc</code>
+ file).</p>

+ <u>How do I place objects, like buildings, into FlightGear?</u></a></b>
+ <div class="indent">
+ <p>First, ensure that you have v0.7.7 or later, the scenery files
+ where you plan to place the object, the actual model, and the
+ longitude and latitude where you plan to place the object.</p>
+ <p>Now get the altitude for your point. If you don't want to
+ calculate this yourself, start FlightGear at your location and take
+ note of the altitude. Here's an example command:</p>
+ <p><code>fgfs --lat=45.50 --lon=-75.73 2>&1 | tee fgfs.log</code></p>
+ <p>The altitude is probably in feet, so divide the starting altitude
+ by 3.28.</p>
+ <p>Search the output log file for the first occurrence of the string
+ "Loading tile" and take note of the filename. In the above example,
+ the output line looks like:</p>
+ <p><code>Loading tile /usr/local/Scenery/w080n40/w076n45/1712601</code></p>
+ <p>Copy a 3D model in a format that Plib understands to the same
+ directory as the tile file. Edit the text file in that directory
+ consisting of the tile name with the extension ".ind". The file will
+ already exist if there is an airport on the tile; otherwise, you can
+ create it from scratch. In our example, the filename is:</p>
+ <p><code>/usr/local/Scenery/w080n40/w076n45/1712601.ind</code></p>
+ <p>At the end of the file, add a new entry for your object,
+ consisting of the word "OBJECT_STATIC" followed by the model name,
+ the longitude in degrees, the latitude in degrees, the altitude in
+ meters, and the heading in degrees. In our example the line looks
+ like:</p>
+ <p><code>OBJECT_STATIC Towerax.ac -75.73 45.40 60 0</code></p>
+ <p>Save the changes to the .ind file, restart FlightGear, and
+ enjoy.</p>
