| 27 | |
| 28 | <h2>1.1 General</h2> |
| 29 | <ul> |
| 30 | <li>lex / yacc - for building the GLSL compiler. |
| 31 | On Linux systems, flex and bison are used. |
| 32 | Versions 2.5.35 and 2.4.1, respectively, (or later) should work. |
| 33 | <br> |
| 34 | <br> |
| 35 | On Windows with MinGW, install flex and bison with: |
| 36 | <pre>mingw-get install msys-flex msys-bison</pre> |
| 37 | </li> |
| 38 | <li>python - Python is needed for building the Gallium components. |
| 39 | Version 2.6.4 or later should work. |
| 40 | <br> |
| 41 | <br> |
| 42 | To build OpenGL ES 1.1 and 2.0 you'll also need |
| 43 | <a href="http://xmlsoft.org/sources/win32/python/libxml2-python-2.7.7.win32-py2.7.exe">libxml2-python</a>. |
| 44 | </li> |
| 45 | </ul> |
| 46 | |
| 47 | |
| 48 | <h3 id="prereq-dri">1.2 For DRI and hardware acceleration</h3> |
| 49 | |
| 50 | <p> |
| 51 | The following are required for DRI-based hardware acceleration with Mesa: |
| 52 | </p> |
| 53 | |
| 54 | <ul> |
| 55 | <li><a href="http://xorg.freedesktop.org/releases/individual/proto/" |
| 56 | target="_parent">dri2proto</a> version 2.6 or later |
| 57 | <li><a href="http://dri.freedesktop.org/libdrm/" target="_parent">libDRM</a> |
| 58 | version 2.4.33 or later |
| 59 | <li>Xorg server version 1.5 or later |
| 60 | <li>Linux 2.6.28 or later |
| 61 | </ul> |
| 62 | <p> |
| 63 | If you're using a fedora distro the following command should install all |
| 64 | the needed dependencies: |
| 65 | </p> |
| 66 | <pre> |
| 67 | sudo yum install flex bison imake libtool xorg-x11-proto-devel libdrm-devel \ |
| 68 | gcc-c++ xorg-x11-server-devel libXi-devel libXmu-devel libXdamage-devel git \ |
| 69 | expat-devel llvm-devel |
| 70 | </pre> |
| 71 | |
| 72 | |
| 73 | |
| 74 | <h1 id="autoconf">2. Building with autoconf (Linux/Unix/X11)</h1> |
| 75 | |
| 76 | <p> |
| 77 | The primary method to build Mesa on Unix systems is with autoconf. |
| 78 | </p> |
| 79 | |
| 80 | <p> |
| 81 | The general approach is the standard: |
| 82 | </p> |
| 83 | <pre> |
| 84 | ./configure |
| 85 | make |
| 86 | sudo make install |
| 87 | </pre> |
| 88 | <p> |
| 89 | But please read the <a href="autoconf.html">detailed autoconf instructions</a> |
| 90 | for more details. |
| 91 | </p> |
| 92 | |
| 93 | |
| 94 | |
| 95 | <h1 id="scons">3. Building with SCons (Windows/Linux)</h1> |
| 96 | |
| 97 | <p> |
| 98 | To build Mesa with SCons on Linux or Windows do |
| 99 | </p> |
| 100 | <pre> |
| 101 | scons |
| 102 | </pre> |
| 103 | <p> |
| 104 | The build output will be placed in |
| 105 | build/<i>platform</i>-<i>machine</i>-<i>debug</i>/..., where <i>platform</i> is for |
| 106 | example linux or windows, <i>machine</i> is x86 or x86_64, optionally followed |
| 107 | by -debug for debug builds. |
| 108 | </p> |
| 109 | |
| 110 | <p> |
| 111 | To build Mesa with SCons for Windows on Linux using the MinGW crosscompiler toolchain do |
| 112 | </p> |
| 113 | <pre> |
| 114 | scons platform=windows toolchain=crossmingw machine=x86 mesagdi libgl-gdi |
| 115 | </pre> |
| 116 | <p> |
| 117 | This will create: |
| 118 | </p> |
| 119 | <ul> |
| 120 | <li>build/windows-x86-debug/mesa/drivers/windows/gdi/opengl32.dll — Mesa + swrast, binary compatible with Windows's opengl32.dll |
| 121 | <li>build/windows-x86-debug/gallium/targets/libgl-gdi/opengl32.dll — Mesa + Gallium + softpipe, binary compatible with Windows's opengl32.dll |
| 122 | </ul> |
| 123 | <p> |
| 124 | Put them all in the same directory to test them. |
| 125 | </p> |
| 126 | |
| 127 | |
| 128 | |
| 129 | <h1 id="other">4. Building for other systems</h1> |
| 130 | |
| 131 | <p> |
| 132 | Documentation for other environments (some may be very out of date): |
| 133 | </p> |
| 134 | |
| 135 | <ul> |
| 136 | <li><a href="README.VMS">README.VMS</a> - VMS |
| 137 | <li><a href="README.CYGWIN">README.CYGWIN</a> - Cygwin |

| 141 | |
| 142 | |
| 143 | <h1 id="libs">5. Library Information</h1> |
| 144 | |
| 145 | <p> |
| 146 | When compilation has finished, look in the top-level <code>lib/</code> |
| 147 | (or <code>lib64/</code>) directory. |
| 148 | You'll see a set of library files similar to this: |
| 149 | </p> |
| 150 | <pre> |
| 151 | lrwxrwxrwx 1 brian users 10 Mar 26 07:53 libGL.so -> libGL.so.1* |
| 152 | lrwxrwxrwx 1 brian users 19 Mar 26 07:53 libGL.so.1 -> libGL.so.1.5.060100* |
| 153 | -rwxr-xr-x 1 brian users 3375861 Mar 26 07:53 libGL.so.1.5.060100* |
| 154 | lrwxrwxrwx 1 brian users 14 Mar 26 07:53 libOSMesa.so -> libOSMesa.so.6* |
| 155 | lrwxrwxrwx 1 brian users 23 Mar 26 07:53 libOSMesa.so.6 -> libOSMesa.so.6.1.060100* |
| 156 | -rwxr-xr-x 1 brian users 23871 Mar 26 07:53 libOSMesa.so.6.1.060100* |
| 157 | </pre> |
| 158 | |
| 159 | <p> |
| 160 | <b>libGL</b> is the main OpenGL library (i.e. Mesa). |
| 161 | <br> |
| 162 | <b>libOSMesa</b> is the OSMesa (Off-Screen) interface library. |
| 163 | </p> |
| 164 | |
| 165 | <p> |
| 166 | If you built the DRI hardware drivers, you'll also see the DRI drivers: |
| 167 | </p> |
| 168 | <pre> |
| 169 | -rwxr-xr-x 1 brian users 16895413 Jul 21 12:11 i915_dri.so |
| 170 | -rwxr-xr-x 1 brian users 16895413 Jul 21 12:11 i965_dri.so |
| 171 | -rwxr-xr-x 1 brian users 11849858 Jul 21 12:12 r200_dri.so |
| 172 | -rwxr-xr-x 1 brian users 16050488 Jul 21 12:11 r300_dri.so |
| 173 | -rwxr-xr-x 1 brian users 11757388 Jul 21 12:12 radeon_dri.so |
| 174 | </pre> |
| 175 | |
| 176 | <p> |
| 177 | If you built with Gallium support, look in lib/gallium/ for Gallium-based |
| 178 | versions of libGL and device drivers. |
| 179 | </p> |
| 180 | |
| 181 | |
| 182 | <h1 id="pkg-config">6. Building OpenGL programs with pkg-config</h1> |
| 183 | |
| 184 | <p> |
| 185 | Running <code>make install</code> will install package configuration files |
| 186 | for the pkg-config utility. |
| 187 | </p> |
| 188 | |
| 189 | <p> |
| 190 | When compiling your OpenGL application you can use pkg-config to determine |
| 191 | the proper compiler and linker flags. |
| 192 | </p> |
| 193 | |
| 194 | <p> |
| 195 | For example, compiling and linking a GLUT application can be done with: |
| 196 | </p> |
| 197 | <pre> |
| 198 | gcc `pkg-config --cflags --libs glut` mydemo.c -o mydemo |
| 199 | </pre> |
