-Download the latest version of plib (1.0.18) from:
- http://www.woodsoup.org/~sbaker/plib/
+1. Requirements
-Configure it with the default prefix of /usr/local which places
-everthing in a tree rooted at /usr/local/plib:
+The following packages should be installed before FlightGear (or SimGear
+or PLib) can be compiled on Irix:
- sh$ CC="cc -Xcpluscomm" CXX=CC ./configure
+ Irix development headers and libraries
+ --------------------------------------
-*Before* running make, fix up the plib Makefiles using the script
-provided with the FlightGear distribution:
+ compiler_dev.sw.base irix_dev.sw.headers
+ compiler_dev.sw.ld dev.sw.lib
+ compiler_dev.sw.util
+ compiler_dev.hdr.lib
- find . -name Makefile -exec .../src/FlightGear-0.7.x/irix-hack.pl {} \;
+ gl_dev.sw.gldev dmedia_dev.sw.base
+ x_dev.sw.dev
-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.
+ MipsPro C and C++ Compiler environment
+ --------------------------------------
-Now, make and install plib.
+ c++_dev.hdr.lib c_dev.sw.c
+ c++_dev.sw.c++ c_fe.sw.c
+ c++_dev.sw.lib
+ c++_eoe.sw.lib
+ c++_fe.sw.c++
-Download the latest fgfs source snapshot from:
- ftp://ftp.flightgear.org/pub/fgfs/Source/Snapshots/
+ FlightGear Flight Simulator Software
+ ----------------------------------------
-Configure and build fgfs as you did plib:
+ FlightGear: http://www.flightgear.org
+ SimGear: http://www.simgear.org
+ Plib: http://plib.sourceforge.net
+ GLUT: http://
- sh$ CC="cc -Xcpluscomm" CXX=CC ./configure
- sh$ find . -name Makefile -exec .../src/FlightGear-0.7.x/irix-hack.pl {} \;

+2. Compiling and Installation
-(Contributed by Todd Smith <msmith@sikorsky.com>)
-and updates by Curt Olson)
+To create a set of binaries it is important to follow these steps. This
+will build a statically linked executable /opt/bin/fgfs
-Download the FlightGear-0.7.x via anonymous cvs as usual, then do:
+ 1. Extract, and install GLUT, following the build guidelines provided
+ by the author of GLUT.
-> aclocal # normal
-> automake -a -i # added '-i' flag to avoid dependency calc
- # that only sgi cc/CC doesn't support
-> autoconf # normal
+ 2. Extract, configure and install Plib:
+ automake -a -i
+ CXXFLAGS="-O2 -G0 -use_readonly_const -rdata_shared -I/opt/include" \
+ CFLAGS=$CXXFLAGS LDFLAGS="-L/opt/lib32" \
+ ./configure --prefix=/opt --libdir=/opt/lib32
+ make; make install
-Note the change in automake's command argument.
+ 3. Extract, configure and install SimGear:
+ automake -a -i
+ CXXFLAGS="-O2 -G0 -use_readonly_const -rdata_shared -I/opt/include \
+ -woff 1001,1012,1014,1116,1172,1174,1401,1460,1551,1552,1681" \
+ CFLAGS="-Xcpluscomm "$CXXFLAGS LDFLAGS="-L/opt/lib32 -L../zlib" \
+ ./configure --prefix=/opt --libdir=/opt/lib32 --with-logging
+ sh ../FlightGear-0.x.x/irix-hack.sh
+ make; make install
-Now set env variables to use native compilers (csh syntax).
+ 4. Extract, configure and install FlightGear:
+ automake -a -i
+ CXXFLAGS="-O2 -G0 -use_readonly_const -rdata_shared -I/opt/include \
+ -woff 1001,1012,1014,1116,1172,1174,1401,1460,1551,1552,1681" \
+ CFLAGS="-Xcpluscomm "$CXXFLAGS LDFLAGS="-L/opt/lib32" \
+ CPPFLAGS="-woff 1014" \
+ ./configure --prefix=/opt --with-simgear=/opt --without-loging
+ sh ./irix-hack.sh
+ make; make install
-> 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.
+The irix-hack.sh script fixes some compiler specific problems which were
+introduced after the adoption of the C++ Standard Template Library.
+Not running this script will result in an error message like this:
+ CC ERROR: -ar option requires archive name to be specified with -o option
-> setenv CPPFLAGS '-woff 1014'
+If this happens, just run the irix-hack script and continue with make.
-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
+The "automake -a -i" command is required because automake with automatic
+dependency building breaks the native Irix compilers.
-Runs great.

+3. Running
--------------------------------------------
-Warnings that I get. Ignore at your lesiure.
+Before the FlightGear program could be run it is important to install the
+FlightGear base package (the default is to extract the base package into
+/opt/bin/lib).
-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
+This package can be found at: http://www.flightgear.org
-C++ only:
-warning(3303): type qualifier on return type is meaningless
-warning(3322): omission of explicit type is nonstandard ("int" assumed)
+When all is set and done, just run /opt/bin/runfgfs
+To see the command line options, run /opt/bin/runfgfs --help
-VII. 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.
