But this doesn't matter since + the Flight Gear executable is then already compiled. + Just make install from toplevel Makefile directory + and up you go... + +----------------------------------------------------------------------- +2.2) "gpc.o" and "gpc.h" + Can anyone advise me on what to do with the gpc.c and gpc.h files. + I retrieved them OK after "configure"reported that they were needed. + But, I don't know what I'm supposed to do with them. + +Ans: Flight Gear's Makefile expects libgpc to be on your System. + Try this: gcc -c gpc.c + ar cru libgpc.a gpc.o + Then copy libgpc.a to some place that your compiler knows about such + as /usr/local/lib, and then try compiling again. A better idea would be + to set LIBRARY_PATH to point to the location where you installed + the libgpc.a file instead of dropping it into a system-wide library + directory. + + Caveat Emptor: + One word of warning to Linux / Unix users. I recently discovered + that the gnu pascal compiler is also called "gpc" and comes with a + libgpc.a I know this has caused confusion on the part of at least one + or two people. + +------------------------------------------------------------------------- +2.3) compiler could not find gfc/... + +e.g. main.cxx:32: gfc/gshapefile.h: No such file or directory + main.cxx:30: gfc/gadt_polygon.h: No such file or directory + main.cxx:31: gfc/gdbf.h: No such file or directory + main.cxx:32: gfc/gshapefile.h: No such file or directory + there is no gadt_polygon.h on my system. What library does it belong to ? + +Ans: This is part of the GFC library it is not needed to run FlightGear + as it is part of the beta Scenery Tool Kit + GFC -- Geographic Foundation Classes library + http://www.geog.psu.edu/~qian/gfc/index.html + +-------------------------------------------------------------------------- +2.4) Red Had 5.1/5.2 related problems + +I quickly ran into problems with the basic_string library. (see undefined ref.) + + c++ -g -O2 -L/usr/local/lib -L/usr/X11R6/lib -o testbucket + testbucket.o../../Lib/Bucket/libBucket.a -lmtestbucket.o: In function + FGBucket::gen_base_path(void)':/usr/include/g++/std/bastring.h:75: undefined + reference to Basic_string, + __default_alloc_template>::Rep::clone(void)'collect2: ld returned 1 + exit statusmake[2]: *** [testbucket] Error 1 + + +Ans: I ran into the same problem on my RedHat 5.2 system (brand new). + After some searching I found out that it's got to do with a 'bug' in + the stdlibc++libraries. I picked up libstdc++-2.9.0-2.i386.rpm, + installed it and FGFS compiled just fine (after some other problems + with gfc, I had to pick up the one from the fgfs site). However, some + other packages must have the libstdc++-2.8 libraries.... + +Ans: I also solved it with the 2.8 libraries by including + /usr/include/g++/std/bastring.cc into the example programs. + I believe this can be done since it's a template. + +========================================================================== + +SECTION THREE : User Questions + + +3.1) Upside down after crash ? + After beeing crashed on the ground the navion continues to fly + upside-down and it stucks at almost groundlevel, + (like cruse missile ;-) flying with a reverse heading as before + and "balancing" left and right. The only solution seems to be + to give full throttle and then at +80-90 kts it can move up by + pressing one of the "elevator arrows" like a rocket doing a loop. + But hey, that's nerving bc the loop is allways to short and the + responding time of navion (correcting the "roll") is also to short, + which results in crash so you have to re-throttle again. + + +Ans: In his infinite wisdom the FlightGear GrandMaster decided + that planes were to valuable to allow them to be destroyed + by novice pilots who seemed to crash alot. + + 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. + + 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 aierlons 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 !!! + +--------------------------------------------------------------------------- +3.2) Ailleron vs Rudder + What's the difference. Both help the plane to turn, that i did understand + +Ans: There is a bit of info on aileron vs. rudder here: + http://www.arundel.net/xplane/html/crosswind.html + http://www.monmouth.com/~jsd/how/ + +--------------------------------------------------------------------------- +3) FG is sooo slow (1 fps), though i got hardware acceleration like + Voodoo/Voodoo2 etc... What's the reason ? + +Ans: Flight Gear supports hardware acceleration, but it seems not + to be activated. Even a P-400 goes berzerk using software rendering. + First check out if you have MESA with glide support. + Linux Users enter "make linux-glide" to compile Mesa + + Check out your environment variables, whether you use soft or hard-ware + rendering. Here an example that should work : + + You have to tell Mesa to use fullscreen + + MESA_GLX_FX=fullscreen + + You also must set the appropriate Voodoo vars, here is for Voodoo2 + the Voodoo1 vars may slightly differ. + + SSTV2_BGAMMA=1.00 + SSTV2_FASTMEM_RAS_READS=1 + SSTV2_FASTPCIRD=1 + SSTV2_GAMMA=1.00 + SSTV2_GGAMMA=1.00 + SSTV2_GRXCLK=95 + SSTV2_RGAMMA=1.00 + SSTV2_SCREENREFRESH=60 + SSTV2_SWAP_EN_WAIT_ON_VSYNC=0 + SSTV2_VGA_PASS=0 + + The Voodoo vars can be obtained at: + http://www.bahnhof.se/~engstrom/e_3dfxvars.htm + + Another good tool is glide-control to set the env. vars, go get it at: + http://www.ling.ed.ac.uk/~oliphant/gc + + Check also the help-startup-screen of Flight Gear: + fgfs --help + +=========================================================================== + +Oliver Delise Maintainer of FAQ +Please send any comments/suggestions/flames or beer to delise@rp-plus.de
