Q: ./configure does not find the libraries?
Make sure to have installed at least OpenGL, GLU, GLUT, OpenGL-devel,
GLU-devel, and GLUT-devel.
The exact package names may vary between Linux distributions.
A good choice for SuSE Linux 8.1 may be Mesa, MesaGLU, MesaGLUT, and
the -devel equivalents.
On RedHat 9 you will have to install GLUT-devel!
Make also sure that the library files are located in /lib or /usr/lib.
For SuSE8.1 the /usr/lib directory must contain libGL.so, libGLU.so,
and libglut.so.
+++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++
Q: ./configure simply does not work?
You may have the wrong versions of automake and autoconf.
Create your own configure script calling
./rebuild
and execute the newly created script
./configure
+++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++
Q: Why is there no sound?
If the game starts up prompting "Using GLUT only", the game has been
compiled without sound. Make sure to have SDL, SDL-devel, SDL_mixer
installed and compile the sources again:
./configure
make
make install
+++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++
Q: How to compile on MacOSX?
In the Makefile, set LIBS to
-framework OpenGL -framework SDL -framework GLUT -framework Foundation
-lSDL_mixer -lSDLmain -framework QuickTime -framework CoreServices
-framework AppKit
Make sure that the library and header files can be found by configure.
+++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++
Q: Libraries are installed, but gcc (linker) does not find them?
Try the command
g++ -g -O2 -lm -o gl-117 main.o gl.o model.o 3ds.o audio.o land.o \
glland.o aiobject.o effects.o roam.o net.o mathtab.o dirs.o \
objload.o pilots.o common.o object.o cockpit.o \
-lGL -lGLU -lglut -lSDL -lSDLmain -lSDL_mixer \
-lXmu -lXext -lXi -lXxf86vm
+++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++
Q: internal error, core dump, submit gcc bug report?
Sorry, the cause is unknown. Just execute make again until everything is
compiled and linked properly.
+++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++
S E C T I O N 2
+++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++
Q: How to alter resolution, color depth?
As the resolution and color depth can not be changed in-game, please edit
the (text) file
$HOME/.gl-117/conf (Unix)
GL-117_DIR\saves\conf (Windows)
and set the corresponding values manually.
+++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++
Q: How to configure the input devices?
Just edit the file
$HOME/.gl-117/conf.interface (Unix)
GL-117_DIR\saves\conf.interface (Windows)
and adjust the settings.
+++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++
Q: The joystick rudder and throttle are swapped?
The joystick axes identification depends on the driver (OS).
Just edit the file conf.interface as described above.
+++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++
Q: Cannot open GLX?
Try another bpp setting in the file conf (described above). (32, 16, 8)
+++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++
Q: Graphics do not initialize?
This game needs properly installed versions of OpenGL, GLU, and GLUT!
+++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++
Q: Graphics too lame?
Sorry, OpenGL is not supported by every graphics card.
You will need at least an Nvidia TNT2 chipset to seriously play the game,
as well as the appropriate drivers.
The game has been tested in 800x600 mode on
AMD K2 500 AGP1x TNT, quality=0, view=50: FPS>30
Athlon 1400 GeForce2, quality=3, view=70: FPS>30
P4 2.4GHz GeForce4, quality=5, view=100: FPS>30
