If you are reading this in hopes that you will find the answer to a
|
|
specific question, please send the question to curt@me.umn.edu and
|
|
suggest that I include the answer here.

Compilers and Portability
|
|
=========================
|
|
|
|
Flight Gear is known to build with egcs-1.1 and higher, as well as
|
|
gcc-2.8 and higher. Your mileage may vary with earlier versions of
|
|
these compilers although support for gcc-2.7.x is mostly there.
|
|
|
|
For other platforms where you may have access to native compilers,
|
|
again your mileage may vary. We would like to support as many
|
|
different compilers and platforms as possible. Please relay any
|
|
changes you make (or problems you encounter) back to
|
|
curt@flightgear.org, so that in the future we can better support your
|
|
platform and your compiler. I have access to a few different
|
|
platforms, but I must depend on others to make sure their favorite
|
|
platform and compiler is well supported.

GLUT
|
|
====
|
|
|
|
Flight Gear requires GLUT version 3.7 or later (aka GameGLUT._ GLUT
|
|
needs to be installed on your system before you can build Flight Gear.
|
|
GLUT can be found at:
|
|
|
|
http://reality.sgi.com/opengl/glut3/glut3.html
|
|
|
|
GLUT (pronounced like the glut in gluttony) is the OpenGL Utility
|
|
Toolkit, a window system independent toolkit for writing OpenGL
|
|
programs. It implements a simple windowing application programming
|
|
interface (API) for OpenGL. GLUT makes it considerably easier to learn
|
|
about and explore OpenGL programming. GLUT provides a portable API so
|
|
you can write a single OpenGL program that works on both Win32 PCs and
|
|
X11 workstations.
|
|
|
|
|
|
Joystick Support
|
|
================
|
|
|
|
GLUT only has win32 joystick support but even at that, it is not well
|
|
implimented. So we use Steve Backer's joystick library when possible,
|
|
and fall back to GLUT for win32 until Steve's library adds win32
|
|
support.
|
|
|
|
To make sure joystick support is included when building under Linux:
|
|
|
|
- make sure you have the proper joystick module installed.
|
|
- make sure the proper devices are created in /dev.
|
|
- /usr/include/linux/joystick.h must exist on your system.
|
|
|
|
|
|
Native SGI Irix Compilers
|
|
=========================
|
|
|
|
If you are building with native SGI compilers try running configure like the
|
|
following (assuming sh syntax):
|
|
|
|
CC=cc CXX=CC CFLAGS=-Xcpluscomm ./configure
|
|
|
|
Then (and this step is *VERY* important for your success) run the following
|
|
command:
|
|
|
|
find . -name Makefile -exec irix-hack.pl {} \;
|
|
|
|
This touches up the Makefiles to build libfoo.a with
|
|
|
|
CC -ar -o libfoo.a file1.o file2.o ...
|
|
|
|
The traditional method is to run:
|
|
|
|
ar cru libfoo.a file1.o file2.o
|
|
|
|
I wonder if this means that the native SGI "ar" is somewhat broke?
|
|
|
|
Note, you should make sure you have perl installed on your system. The
|
|
"irix-hack.pl" script assumes that perl is located in /usr/bin/perl so
|
|
if this isn't the proper location on your system, change it in the first
|
|
line of "irix-hack.pl" before running the above command. One way to see
|
|
if perl is on your system (and determine where) is to run:
|
|
|
|
which perl
|
|
|
|
Perl can be installed from "eoe.sw.gifts_perl" or can be fetched and
|
|
built from the net.
|
|
|
|
Finally you should run Gnu make. The native Irix make utility just
|
|
can't handle the makefiles generated by the automake program. Thus
|
|
you will need to use Gnu make. It's called "gmake" on my system so I
|
|
just run:
|
|
|
|
gmake
|
|
|
|
Don't worry about the make failing in the Tools directory. That's all
|
|
under construction stuff right now (3/9/99) and if you get that far,
|
|
rejoice because it means the simulator was successfully built in the
|
|
Simulator/Main subdirectory.
