-Compilers and Portability
-=========================
+I. 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
platform and compiler is well supported.
-GLUT
-====
+II. 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.
X11 workstations.
-Joystick Support
-================
+III. 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,
- /usr/include/linux/joystick.h must exist on your system.
-Native SGI Irix Compilers
-=========================
+IV. Procedure to build FGFS with Native SGI Irix Compilers from CVS Sources
+===========================================================================
+
+(Contributed by Todd Smith <msmith@sikorsky.com>)
+
+Download the latest version of plib (1.0.3) from:
+
+ http://www.woodsoup.org/~sbaker/plib/
+
+Install it both in /usr/local/plib and /usr/local/include/plib. I
+think that I am using it from /usr/local/include.
+
+Download the FlightGear-0.6 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.

+-------------------------------------------
+Warnings that I get. Ignore at your lesiure.
+
+C and C++:
+warning(1001): last line of file ends without a newline
+warning(1012): parsing restarts here after previous syntax error
+warning(1014): extra text after expected end of preprocessing directive (breaks configure)
+warning(1116): non-void function "poly_index_init" should return a value
+warning(1172): subscript out of range
+warning(1174): variable "j" was declared but never referenced
+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
+
+C++ only:
+warning(3303): type qualifier on return type is meaningless
+warning(3322): omission of explicit type is nonstandard ("int" assumed)
+
+
+V. Additional Native SGI Irix Compilers Notes
+=============================================
If you are building with native SGI compilers try running configure like the
following (assuming sh syntax):
- CC=cc CXX=CC CFLAGS=-Xcpluscomm ./configure
+ CC=cc CXX=CC CFLAGS="-Xcpluscomm -woff 1014" ./configure
Then (and this step is *VERY* important for your success) run the following
command:
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.
+
+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.
