<h1 class="chapter" id="sec587">Chapter 34 The bigarray library</h1>
<p>The <span class="c003">bigarray</span> library has now been integrated into OCaml’s standard
library.</p><p>The <span class="c003">bigarray</span> functionality may now be found in the standard library
<a href="libref/Bigarray.html"><span class="c003">Bigarray</span> module</a>,
except for the <span class="c003">map_file</span> function which is now
part of the <a href="libunix.html#c%3Aunix">Unix library</a>. The documentation has
been integrated into the documentation for the standard library.</p><p>The legacy <span class="c003">bigarray</span> library bundled with the compiler is a
compatibility library with exactly the same interface as before,
i.e. with <span class="c003">map_file</span> included.</p><p>We strongly recommend that you port your code to use the standard
library version instead, as the changes required are minimal.</p><p>If you choose to use the compatibility library, you must link your
programs as follows:
</p><pre>
ocamlc <span class="c009">other options</span> bigarray.cma <span class="c009">other files</span>
ocamlopt <span class="c009">other options</span> bigarray.cmxa <span class="c009">other files</span>
</pre><p>
For interactive use of the <span class="c003">bigarray</span> compatibility library, do:
</p><pre>
ocamlmktop -o mytop bigarray.cma
./mytop
</pre><p>
or (if dynamic linking of C libraries is supported on your platform),
start <span class="c003">ocaml</span> and type <span class="c003">#load "bigarray.cma";;</span>.
