 <h1 id="prereq-general">1. Prerequisites for building</h1>

 <h2>1.1 General</h2>

 <p>
 Build system.
 </p>

 <ul>
 <li>Autoconf is required when building on *nix platforms.
 <li><a href="http://www.scons.org/">SCons</a> is required for building on
 Windows and optional for Linux (it's an alternative to autoconf/automake.)
 </li>
 <li>Android Build system when building as native Android component. Autoconf
 is used when when building ARC.
 </li>
 </ul>


 <p>
 The following compilers are known to work, if you know of others or you're
 willing to maintain support for other compiler get in touch.
 </p>

 <ul>
 <li>GCC 4.2.0 or later (some parts of Mesa may require later versions)
 <li>clang - exact minimum requirement is currently unknown.
 <li>Microsoft Visual Studio 2013 Update 4 or later is required, for building on Windows.
 </ul>


 <p>
 Third party/extra tools.
 <br>
 <strong>Note</strong>: These should not be required, when building from a release tarball. If
 you think you've spotted a bug let developers know by filing a
 <a href="bugs.html">bug report</a>.
 </p>


 <ul>
 <li><a href="https://www.python.org/">Python</a> - Python is required.
 Version 2.6.4 or later should work.
 </li>
 <li><a href="http://www.makotemplates.org/">Python Mako module</a> -
 Python Mako module is required. Version 0.3.4 or later should work.
 </li>
 <li>lex / yacc - for building the Mesa IR and GLSL compiler.
 <div>
 On Linux systems, flex and bison versions 2.5.35 and 2.4.1, respectively,
 (or later) should work.
 On Windows with MinGW, install flex and bison with:
 <pre>mingw-get install msys-flex msys-bison</pre>
 For MSVC on Windows, install
 <a href="http://winflexbison.sourceforge.net/">Win flex-bison</a>.
 </div>
 </ul>
 <p><strong>Note</strong>: Some versions can be buggy (eg. flex 2.6.2) so do try others if things fail.</p>


 <h3 id="prereq-dri">1.2 Requirements</h3>

 <p>
 The requirements depends on the features selected at configure stage.
 Check/install the respective -devel package as prompted by the configure error
 message.
 </p>

 <p>
 Here are some common ways to retrieve most/all of the dependencies based on
 the packaging tool used by your distro.
 </p>

 <pre>
   zypper source-install --build-deps-only Mesa # openSUSE/SLED/SLES
   yum-builddep mesa # yum Fedora, OpenSuse(?)
   dnf builddep mesa # dnf Fedora
   apt-get build-dep mesa # Debian and derivatives
   ... # others
 </pre>


 <h1 id="autoconf">2. Building with autoconf (Linux/Unix/X11)</h1>

 <p>
 The primary method to build Mesa on Unix systems is with autoconf.
 </p>

 <p>
 The general approach is the standard:
 </p>
 <pre>
   ./configure
   make
   sudo make install
 </pre>
 <p>
 But please read the <a href="autoconf.html">detailed autoconf instructions</a>
 for more details.
 </p>


 <h1 id="scons">3. Building with SCons (Windows/Linux)</h1>

 <p>
 To build Mesa with SCons on Linux or Windows do
 </p>
 <pre>
     scons
 </pre>
 <p>
 The build output will be placed in
 build/<i>platform</i>-<i>machine</i>-<i>debug</i>/..., where <i>platform</i> is for
 example linux or windows, <i>machine</i> is x86 or x86_64, optionally followed
 by -debug for debug builds.
 </p>

 <p>
 To build Mesa with SCons for Windows on Linux using the MinGW crosscompiler toolchain do
 </p>
 <pre>
     scons platform=windows toolchain=crossmingw machine=x86 libgl-gdi
 </pre>
 <p>
 This will create:
 </p>
 <ul>
 <li>build/windows-x86-debug/gallium/targets/libgl-gdi/opengl32.dll &mdash; Mesa + Gallium + softpipe (or llvmpipe), binary compatible with Windows's opengl32.dll
 </ul>
 <p>
 Put them all in the same directory to test them.

 Additional information is available in <a href="README.WIN32">README.WIN32</a>.

 </p>


 <h1 id="android">4. Building with AOSP (Android)</h1>

 <p>
 Currently one can build Mesa for Android as part of the AOSP project, yet
 your experience might vary.
 </p>

 <p>
 In order to achieve that one should update their local manifest to point to the
 upstream repo, set the appropriate BOARD_GPU_DRIVERS and build the
 libGLES_mesa library.
 </p>

 <p>
 FINISHME: Improve on the instructions add references to Rob H repos/Jenkins,
 Android-x86 and/or other resources.
 </p>


 <h1 id="libs">5. Library Information</h1>

 <p>
 When compilation has finished, look in the top-level <code>lib/</code>
 (or <code>lib64/</code>) directory.
 You'll see a set of library files similar to this:
 </p>
 <pre>
 lrwxrwxrwx    1 brian    users          10 Mar 26 07:53 libGL.so -> libGL.so.1*
 lrwxrwxrwx    1 brian    users          19 Mar 26 07:53 libGL.so.1 -> libGL.so.1.5.060100*
 -rwxr-xr-x    1 brian    users     3375861 Mar 26 07:53 libGL.so.1.5.060100*
 lrwxrwxrwx    1 brian    users          14 Mar 26 07:53 libOSMesa.so -> libOSMesa.so.6*
 lrwxrwxrwx    1 brian    users          23 Mar 26 07:53 libOSMesa.so.6 -> libOSMesa.so.6.1.060100*
 -rwxr-xr-x    1 brian    users       23871 Mar 26 07:53 libOSMesa.so.6.1.060100*
 </pre>

 <p>
 <b>libGL</b> is the main OpenGL library (i.e. Mesa).
 <br>
 <b>libOSMesa</b> is the OSMesa (Off-Screen) interface library.
 </p>

 <p>
 If you built the DRI hardware drivers, you'll also see the DRI drivers:
 </p>
 <pre>
 -rwxr-xr-x   1 brian users 16895413 Jul 21 12:11 i915_dri.so
 -rwxr-xr-x   1 brian users 16895413 Jul 21 12:11 i965_dri.so
 -rwxr-xr-x   1 brian users 11849858 Jul 21 12:12 r200_dri.so
 -rwxr-xr-x   1 brian users 11757388 Jul 21 12:12 radeon_dri.so
 </pre>

 <p>
 If you built with Gallium support, look in lib/gallium/ for Gallium-based
 versions of libGL and device drivers.
 </p>


 <h1 id="pkg-config">6. Building OpenGL programs with pkg-config</h1>

 <p>
 Running <code>make install</code> will install package configuration files
 for the pkg-config utility.
 </p>

 <p>
 When compiling your OpenGL application you can use pkg-config to determine
 the proper compiler and linker flags.
 </p>

 <p>
 For example, compiling and linking a GLUT application can be done with:
 </p>
 <pre>
    gcc `pkg-config --cflags --libs glut` mydemo.c -o mydemo
 </pre>
