Hi fellow wiki editors!

To help newly registered users get more familiar with the wiki (and maybe older users too) there is now a {{Welcome to the wiki}} template. Have a look at it and feel free to add it to new users discussion pages (and perhaps your own).

I have tried to keep the template short, but meaningful. /Johan G

Compiling FlightGear under the MSYS command line environment

Comments/suggestions/flames to the flightgear-devel list

This gives instructions on how to build FlightGear under the MSYS environment. This was written for compiling a CVS checkout at 01/05/2004. I assume you have a fairly minimal knowledge of standard unix commands. You also need a working CVS client at present.

1) Download MingW from www.mingw.org. (Downloads page, look for MingW-x.x.x.exe among the plethora of packages)

2) Install it. I installed it to C:\mingw, but one could conceivably install it anywhere. It isn't material.

3) Download MSYS from www.mingw.org (Downloads page again, this time look for MSYS-x.x.x.exe)

4) Install that. After it has installed, it will ask to do a post install process. Let it. It will ask you for where you installed MingW. Give it the path you installed in step 2)

5) Download and install the Creative OpenAL SDK (follow link from www.openal.org)

6) Create a folder to put your fgfs sources in. I used C:\fg (under msys, this is /c/fg )

7) Download Plib 1.8.3 (though anything later than 1.7.0 should work) from www.plib.org

(NOTE: If FG 0.9.5 is out, you can skip the next two steps and grab the files straight from www.flightgear.org) (CVS instructions are available at www.flightgear.org)

8) Checkout SimGear from cvs.simgear.org:/var/cvs/SimGear-0.3

9) Checkout FlightGear from cvs.flightgear.org:/var/cvs/FlightGear-0.9

10) Run msys.

Type :

mkdir /fg

CD to the directory you have your source files in (that you made in step 6) If you followed step 6:

cd /c/fg

11) Install Andy's binary libraries.

Download http://plausible.org/andy/fgfs-mingw-libs.tar.gz to C:\fg Type (in MSYS)

cd /fg
tar xvzf /c/fg/fgfs-mingw-libs.tar.gz
tar xvf openal.tar
tar xvf pthread.tar
tar xvf sdl.tar
tar xvf zlib.tar

Rename /fg/bin/pthread.dll to pthreadGC.dll

NOTE: You may have to find pthread.h (in /fg/include) and comment out line 154, the line containing #include "config.h", if you get a build error when building SimGear


12) Download and install Glut

The compilation of flightgear requires that Glut be present, even though plib may be compiled without it. Download Glut for MinGW32 libraries from http://mywebpage.netscape.com/PtrPck/glut.htm and unzip it in a folder.

As of July 12, 2006, the direct link to the zip file is http://mywebpage.netscape.com/PtrPck/glutming.zip

From the folder where you unzipped the archive:

Copy GLUTMingw32/lib/libglut32.a into /fg/lib

Copy GLUTMingw32/include/GL/glut.h into /fg/include/GL

Copy GLUTMingw32/glut32.dll into /fg/bin

13) Build and Install plib

Type

cd /c/fg
tar xvzf plib-1.8.3.tar.gz
cd plib-1.8.3.tar.gz
./configure --prefix=/fg
make
make install

14) Build and Install SimGear

If you grabbed a tarball off the website, untar it before proceeding

cd /c/fg
cd simgear
./autogen.sh
./configure --prefix=/fg
make
make install

15) Build and Install FlightGear

If you grabbed a tarball off the website, untar it before proceeding (and substitute source for your fg src directory?

At present, we only make the /src directory as the others do not work automatically?

cd /c/fg
cd source
./autogen.sh
./configure --prefix=/fg
cd src
make
make install

16) Strip the binaries

cd /fg/bin
strip *.exe

17) Install the base package (from CVS or the website) and tell FlightGear where it is.

18) Fly.
