  20 <H2>1. Unix/X11 Compilation and Installation</H1>
  21
  22 <p>
  23 Mesa uses a rather conventional Makefile system.
  24 A GNU autoconf/automake system used to be included, but was discarded
  25 in Mesa 5.1 because:
  26 </p>
  27 <ul>
  28 <li>It seldom worked on IRIX, Solaris, AIX, etc.
  29 <li>It was very compilicated
  30 <li>Nobody maintained it
  31 <li>libtool was just too weird
  32 </ul>
  33 <p>
  34 If someone strongly feels that Mesa should have a autoconf/automake
  35 system and wants to contribute one and maintain it, we'll consider
  36 adding it again.
  37 </p>

  40 <h3>1.1 Compilation</h3>
  41
  42 <p>
  43 Note: if you've obtained Mesa through CVS, do this first:
  44 </p>
  45 <pre>
  46     cd Mesa-newtree
  47     cp Makefile.X11 Makefile
  48     chmod a+x bin/mklib
  49 </pre>
  50
  51 <p>
  52 Now, just type <b>make</b>.
  53 You'll see a list of supported system configurations.
  54 Choose one from the list (such as linux-x86), and type:
  55 </p>
  56 <pre>
  57     make linux-x86
  58 </pre>
  59 <p>
  60 That's it.
  61 </p>
  62
  63 <h3>1.2 The libraries</h3>
  64
  65 <p>
  66 When compilation has finished, look in the top-level <b>lib/</b> directory.
  67 You'll see a set of library files similar to this:
  68 </p>
  69 <pre>
  70 lrwxrwxrwx    1 brian    users          10 Sep  4 17:55 libGL.so -> libGL.so.1*
  71 lrwxrwxrwx    1 brian    users          19 Sep  4 17:55 libGL.so.1 -> libGL.so.1.4.050100*
  72 -rwxr-xr-x    1 brian    users    13940317 Sep  4 17:55 libGL.so.1.4.050100*
  73 lrwxrwxrwx    1 brian    users          11 Sep  4 17:54 libGLU.so -> libGLU.so.1*
  74 lrwxrwxrwx    1 brian    users          20 Sep  4 17:54 libGLU.so.1 -> libGLU.so.1.3.050100*
  75 -rwxr-xr-x    1 brian    users      324746 Sep  3 13:54 libGLU.so.1.1*
  76 -rwxr-xr-x    1 brian    users     2830539 Sep  4 17:54 libGLU.so.1.3.050100*
  77 lrwxrwxrwx    1 brian    users          12 Sep  4 17:53 libglut.so -> libglut.so.3*
  78 lrwxrwxrwx    1 brian    users          16 Sep  4 17:53 libglut.so.3 -> libglut.so.3.7.1*
  79 -rwxr-xr-x    1 brian    users     2426683 Sep  4 17:53 libglut.so.3.7.1*

  82 <p>
  83 <b>libGL</b> is the main OpenGL library (i.e. Mesa).
  84 <br>
  85 <b>libGLU</b> is the OpenGL Utility library.
  86 <br>
  87 <b>libglut</b> is the GLUT library.
  88 </p>

  91 <h3>1.3 Running the demos</h3>
  92
  93 <p>
  94 If you downloaded/unpacked the MesaDemos-x.y.z.tar.gz archive or
  95 obtained Mesa from CVS, the <b>progs/</b> directory will contain a
  96 bunch of demonstration programs.
  97 </p>
  98
  99 <p>
 100 Before running a demo, you may have to set an environment variable
 101 (such as <b>LD_LIBRARY_PATH</b> on Linux) to indicate where the
 102 libraries are located.  For example:
 103 <p>
 104 <blockquote>
 105 <b>cd</b> into the Mesa <b>lib/</b> directory.
 106 <br>
 107 <b>setenv LD_LIBRARY_PATH ${cwd}</b>   (if using csh or tcsh shell)
 108 <br>
 109 or,
 110 <br>
 111 <b>export LD_LIBRARY_PATH=${PWD}</b>   (if using bash or sh shell)
 112 </blockquote>
 113
 114 <p>
 115 Next, change to the Mesa/demos/ directory:
 116 </p>
 117 <blockquote>
 118 <b>cd ../progs/demos</b>
 119 </blockquote>
 120
 121 <p>
 122 Run a demo such as gears:
 123 </p>
 124 <blockquote>
 125 <b>./gears</b>
 126 </blockquote>
 127
 128 <p>
 129 If this doesn't work, try the <b>Mesa/progs/xdemos/glxinfo</b> program
 130 and see that it prints the expected Mesa version number.
 131 </p>
 132
 133 <p>
 134 If you're using Linux or a similar OS, verify that the demo program is
 135 being linked with the proper library files:
 136 </p>
 137 <blockquote>
 138 <b>ldd gears</b>
 139 </blockquote>
 140
 141 <p>
 142 You should see something like this:
 143 </p>

 169 <H3>1.4 Installing the header and library files</H3>
 170
 171 <p>
 172 The standard location for the OpenGL header files on Unix-type systems is
 173 in <code>/usr/include/GL/</code>.
 174 The standard location for the libraries is <code>/usr/lib/</code>.
 175 For more information see, the
 176 <a href="http://oss.sgi.com/projects/ogl-sample/ABI/" target="_parent">
 177 Linux/OpenGL ABI specification</a>.
 178 </p>
 179
 180 <p>
 181 If you'd like Mesa to co-exist with another implementation of OpenGL that's
 182 already installed, you'll have to choose different directories, like
 183 <code>/usr/local/include/GL/</code> and <code>/usr/local/lib/</code>.
 184 </p>
 185
 186 <p>
 187 To install the Mesa headers, do this:
 188 <blockquote>
 189 <b>cp -r include/GL /usr/include</b>
 190 </blockquote>
 191
 192 <p>
 193 To install the Mesa libraries, do this:
 194 </p>
 195 <blockquote>
 196 <b>cp -pd lib/* /usr/lib</b>
 197 <br>
 198 (The -pd options preserve symbolic links)
 199 </blockquote>
 200
 201 <p>
 202 If you install the libraries in a non-standard location you can use
 203 LD_LIBRARY_PATH (on Linux) to switch between the Mesa libs and another
 204 vendor libs whenever you want.
 205 This is a handy way to compare multiple OpenGL implementations.
