    <h2>System requirements</h2>

    <p>
    At present, <acronym>deal.II</acronym> has been
    developed and tested on the following platforms:
    <ul>
      <li>Linux on x86, with gcc 3.3, 3.4, 4.0, 4.1 and 4.2; and
          Intel ICC 7.0, 7.1, 8.0, 8.1, 9.0, and 10.0;
      <li>Linux on x86_64 (Opterons, AMD64, and Intel EM64T chips) using gcc
          3.3, 3.4, 4.0, and 4.1;
      <li>Mac OS X 10.2, 10.3, and 10.4 (on both PowerPC and Intel
          processors) with gcc 3.x, 4.0, and 4.1;
      <li>Sun Solaris 2.5, 2.6, 7, 8, and 9 on Sparc, with
          gcc 3.2, 3.3, 3.4; 
      <li>Linux on IA-64 (Itanium), using gcc 3.4.2, 4.1.2 and ICC
          9.1, ICC 10.0;
      <li>Linux on x86, with the PathScale EKOPath compiler version
          2.2 (though only with static instead of shared libraries);
      <li>Linux on x86, with Portland Groups (PGI) pgCC compiler
          version 6.2;
      <li><a href="http://www.cygwin.com">Cygwin/Windows</a> with
          cygwin1.dll versions 1.5.xx, and gcc 3.3 and 3.4 under Windows XP
          and NT.
    </ul>
    Newer versions of the compilers listed above are also likely to
    work, as are other brands of Unix (for example Sun Solaris,
    FreeBSD, or Linux on chips like SPARC, PA-RISC, PowerPC, etc) using
    gcc as compiler, but we do not regularly test them.
    Furthermore, for the following list of systems, we have collected
    our experiences on separate pages:
    <ul>
      <li> <a href="platforms/sgi-irix.html" target="body">SGI
           IRIX64</a> with gcc 3.2, 3.3 and 3.4, and with MIPSpro 7.41;

      <li> <a href="platforms/dec-osf5.html" target="body">OSF1 V5.3 on
           Alpha</a> with gcc newer than 2.95.x (the same notes probably also
	   apply to Linux on DEC Alpha) and using DEC's cxx compiler version
           6.3; for older systems with OSF1 4.0 and cxx6.0 please see
