In case you are on a Win32 (i. e. Windows95/98/ME/NT/2000/XP) platform or any of the other platforms which binary executables are available for, you may not want to go though that potentially troublesome process but skip that chapter instead and straightly go to the next one. (Not everyone wants to build his or her plane himself or herself, right?) However, there may be good reason for at least trying to build the simulator: <ul class="itemize1"> <li class="itemize">In case you are on a UNIX<a name="dx6-10001"></a>/Linux<a name="dx6-10002"></a> platform there may be no pre-compiled binaries<a name="dx6-10003"></a> available for your system. In practice it is common to install programs like this one on UNIX<a name="dx6-10004"></a> systems by recompiling them. </li> <li class="itemize">There are several options you can set during compile time only. </li> <li class="itemize">You may be proud you did.</li></ul> <!--l. 51--><p class="noindent">On the other hand, compiling <span class="ptmbi7t---109">FlightGear </span>is not a task for novice users. Thus, if you’re a beginner (we all were once) on a platform which binaries<a name="dx6-10005"></a> are available for, we recommend postponing this task and just starting with the binary distribution<a name="dx6-10006"></a> to get you flying. <!--l. 56--><p class="indent"> As you will notice, this Chapter is far from being complete. Basically, we describe compiling for two operating systems only, Windows<a name="dx6-10007"></a> and Linux<a name="dx6-10008"></a>, and for only one compiler, the GNU C compiler. <span class="ptmbi7t---109">FlightGear </span>has been shown to be built under different compilers (including Microsoft Visual C) as well as different systems (Macintosh) as well. The reason for these limitations are: <ul class="itemize1"> <li class="itemize">Personally, we have access to a Windows machine running the Cygnus compiler only. </li> <li class="itemize">According to the mailing lists, these seem to be the systems with the largest user base. </li> <li class="itemize">These are the simplest systems to compile <span class="ptmbi7t---109">FlightGear </span>on. Other compilers may need special add-ons (workplace etc.) or even modification of the code. </li> <li class="itemize">The GNU compiler is free in the same sense of the GPL as <span class="ptmbi7t---109">FlightGear </span>is.</li></ul> <!--l. 70--><p class="noindent">You might want to check Section <a href="getstartap1.html#x12-66000A">A<!--tex4ht:ref: missed--></a>, <span class="ptmri7t---109">Missed approach</span>, if anything fails during compilation. In case this does not help we recommend sending a note to one of the mailing lists (for hints on subscription see Chapter <a href="getstartap3.html#x14-80000C">C<!--tex4ht:ref: landing--></a>). <!--l. 73--><p class="indent"> There are several Linux distributions<a name="dx6-10009"></a> on the market, and most of them should work. Some come even bundled with (often outdated) versions of <span class="ptmbi7t---109">FlightGear</span>. However, if you are going to download or buy a distribution, Debian<a name="dx6-10010"></a> (Woody) is suggested by most people. SuSE<a name="dx6-10011"></a> works well, too. <!--l. 77--><p class="indent"> Contrary to Linux/Unix systems, Windows usually comes without any development tools. This way, you first have to install a development environment. On Windows, in a sense, before building the plane you will have to build the plant for building planes. This will be the topic of the following section, which can be omitted by Linux users. <h3 class="sectionHead"><span class="titlemark">2.1</span> <a href="getstart.html#QQ2-6-11" name="x6-110002.1">Preparing the development environment under Windows</a></h3> <!--l. 86--><p class="noindent">There is a powerful development environment available for Windows and this even for free: The Cygnus development tools,<a name="dx6-11001"></a> resp. <span class="ptmbi7t---109">Cygwin</span>.

Create a temporary directory and download the installer from the site named above to that directory. (While the installer does an automatic installation of the Cygnus environment, it is a good idea to download a new installer from time to time.) <!--l. 104--><p class="indent"> Invoke the installer now. It gives you three options. To avoid having to download stuff twice in case of a re-installation or installation on a second machine, we highly recommended to take a two-step procedure. First, select the option <span class="pcrr7t---109">Download</span> <span class="pcrr7t---109">from Internet</span>. Insert the path of your temporary directory, your Internet connection settings and then choose a mirror form the list.

We found <!--l. 112--><p class="indent"> <a href="ftp://mirrors.rcn.net" >ftp://mirrors.rcn.net</a> <!--l. 115--><p class="noindent">a very recent and fast choice.

After confirming the temporary directory you can select a root directory (acting as the root directory of your pseudo UNIX file system). Cygnus does not recommend taking the actual root directory of a drive, thus choose <span class="pcrr7t---109">c:/Cygwin </span>(while other drives than <span class="pcrr7t---109">c: </span>work as well). Now, all <span class="ptmbi7t---109">Cygwin </span>stuff and all <span class="ptmbi7t---109">FlightGear </span>stuff lives under this directory.
