IV. 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.
|
||||
We use the plib joystick library for joystick 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.

IV. Procedure to build FGFS with Native SGI Irix Compilers from CVS Sources
|
||||
===========================================================================
|
||||
|
||||
(Contributed by Todd Smith <msmith@sikorsky.com> with modifications
|
||||
and updates by Curt Olson)
|
||||
|
||||
Download the latest version of plib (1.0.18) from:
|
||||
|
||||
http://www.woodsoup.org/~sbaker/plib/
|
||||
|
||||
Configure it with the default prefix of /usr/local which places
|
||||
everthing in a tree rooted at /usr/local/plib:
|
||||
|
||||
sh$ CC="cc -Xcpluscomm" CXX=CC ./configure
|
||||
|
||||
*Before* running make, fix up the plib Makefiles using the script
|
||||
provided with the Flight Gear distribution:
|
||||
|
||||
find . -name Makefile -exec .../src/FlightGear-0.7.x/irix-hack.pl {} \;
|
||||
|
||||
This applies a fix in all the Makefiles to the lib creation command
|
||||
(to use CC -ar rather than ar) as per a tip in the SGI pipeline
|
||||
periodical.
|
||||
|
||||
Now, make and install plib.
|
||||
|
||||
Download the latest fgfs source snapshot from:
|
||||
|
||||
ftp://ftp.flightgear.org/pub/fgfs/Source/Snapshots/
|
||||
|
||||
Configure and build fgfs as you did plib:
|
||||
|
||||
sh$ CC="cc -Xcpluscomm" CXX=CC ./configure
|
||||
sh$ find . -name Makefile -exec .../src/FlightGear-0.7.x/irix-hack.pl {} \;
|
||||

||||

||||
V. Additional Notes for Building from CVS Sources
|
||||
==================================================
|
||||
|
||||
(Contributed by Todd Smith <msmith@sikorsky.com>)
|
||||
and updates by Curt Olson)
|
||||
|
||||
Download the FlightGear-0.7.x via anonymous cvs as usual, then do:
|
||||
|
||||
> aclocal # normal
|
||||
> automake -a -i # added '-i' flag to avoid dependency calc
|
||||
# that only sgi cc/CC doesn't support
|
||||
> autoconf # normal
|
||||
|
||||
Note the change in automake's command argument.
|
||||
|
||||
Now set env variables to use native compilers (csh syntax).
|
||||
|
||||
> setenv CC cc
|
||||
> setenv CXX CC
|
||||
> setenv CFLAGS '-Xcpluscomm -DEBUG:suppress=1001,1012,1014,
|
||||
1116,1172,1174,1401,1460,1551,1552'
|
||||
> setenv CXXFLAGS '-DEBUG:suppress=1001,1012,1014,1116,1172,
|
||||
1174,1401,1460,1551,1552,3303,3322'
|
||||
|
||||
The '-DEBUG:suppress=' stuff just suppresses anonying warnings during
|
||||
compile. The meaning of each one is shown later in this file.
|
||||
You can use all or none of these here.
|
||||
|
||||
> setenv CPPFLAGS '-woff 1014'
|
||||
|
||||
This is required so that configure will really believe that plib
|
||||
is installed. ( Otherwise a compiler warning makes configure
|
||||
that plib/pu.h couldn't be found. )
|
||||
|
||||
> ./configure
|
||||
> find . -name Makefile -exec irix-hack.pl {} \; # normal irix hack
|
||||
> gmake
|
||||
|
||||
Runs great.

|
||||
warning(1014): extra text after expected end of preprocessing directive (breaks configure)
|
||||

|
||||

|
||||

|
||||
warning(1401): qualified name is not allowed in member declaration
|
||||
warning(1460): function "..." redeclared "inline" after being called
|
||||
warning(1551): variable "Altitude" is used before its value is set
|
||||
warning(1552): variable "last" was set but never used
|
||||
|
||||

|
||||
warning(3303): type qualifier on return type is meaningless
|
||||
warning(3322): omission of explicit type is nonstandard ("int" assumed)

VI. Additional Native SGI Irix Compilers Notes
|
||||
==============================================
|
||||
|
||||
Fixing all the Makefiles' with irix-hack.pl is *VERY* important for
|
||||
your success):
|
||||
|
||||
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 (10/7/99) and if you get that far,
|
||||
rejoice because it means the simulator was successfully built in the
|
||||
Simulator/Main subdirectory.
|
||||
|
||||
Special note for those Irix users using the native compilers *AND* checking
|
||||
out the current source tree via CVS:
|
||||
|
||||
You will need to run "aclocal ; automake -a ; autoconf" as per
|
||||
README.autoconf, but you need an additional flag for automake to disable
|
||||
automatic dependency building (which breaks the native Irix compilers.)
|
||||
You should instead run:
|
||||
|
||||
aclocal ; automake -a --include-deps; autoconf
|
||||
|
||||
Then, proceed on to the configure step.
|
||||
|
||||
Questions? I realize this section is a big heap of random information so
|
||||
if something isn't quite working for you, please ask.
