+\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
+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
