<h3>Configuring STLport for new compiler with UNIX shell</h3>
<p><i>Note: this document describes the procedure ot tuning STLport for
new compiler, not the one that is already supported. If your compiler is listed
as supported, this is absolutely unnecessary.</i></p>
<p>STLport comes with "configure" shell script to help in the
initial step to tune the library for a new compiler.
It sets up stlconf.h configuration header
with proper flags depending on features of the compiler and user-defined
options.
Recommended way to create new configuration is to run "configure"
in "config/new_compiler" directory and create <b>stl_yourcompiler.h</b> in "config"
directory based on switches defined by "configure" in stlconf.h.
<b>Do not</b> expect STLport to be configured just by running "configure".
</p>
<p>Here is an example how to specify the parameters to "configure" (for Bourne-like
shells): <b><br>
host&gt; cd STLport/config<br>
host&gt; CXX=CC CXXFLAGS="-xwe -noex" ./configure --enable-malloc</b></p>
<p>This will set up workarounds necessary for "<b>CC</b>"
compiler as well as specify malloc-based allocator as the default one. <br>
Run "<b>configure --help</b>" to see list of options
available. For most reliable results, you should specify <b>CXXFLAGS</b>
to contain the option turning warnings into errors.
"configure" tries to scan warnings, but that not always works.
After testing your compiler features and setting options specified,
"configure" creates <b>stlconf.h</b> file using <b>config/stlconf.h</b>
as input. Macro <b>__AUTO_CONFIGURED</b> indicates that the package has
been configured. If it is not set (before you run configure), <b>stlconf.h</b>
includes <b>stlcomp.h</b> header to set up conservative configuration
and recognize the compiler version. <b>config/stlconf.h</b> can be
safely copied to stlconf.h to restore unconfigured status-quo.</p>
<h3>Configuring STLport on other platforms</h3>
The above may also work on other systems with UNIX-like toolsets on&nbsp;
them.&nbsp; <br>
For example, the <a href="http://www.cygnus.com">cygwin32</a>&nbsp;
suite for Windows 95/NT runs "configure" just fine.&nbsp;&nbsp;&nbsp;
<br>
You can also change &lt;stlcomp.h&gt; for your system manually.<br>
Please consider contributing your changes back to the&nbsp; STLport
project!
<h3>"configure" synopsys (Bourne shells):</h3>
<p>&gt; [environment] <b>./configure</b> [user-defined options]</p>
<h3>"configure" synopsys (C-shells):</h3>
<p>&gt; <b>env </b>[environment] <b>./configure</b> [user-defined
options]</p>
<p><b>"configure" script runs series of tests to determine
detailed characteristics of your compiler.</b></p>
<p>In [environment] , you may specify the following parameters</p>
<p><b>CXX=&lt;compiler_name&gt;, </b>default is <b>c++</b></p>
<p><b>CXXFLAGS=&lt;<i>cxx compiler flags you will most likely use</i>&gt;
. <br>
</b>That may be needed to set up some features correctly. That is, if
you plan to use exception handling, and your compiler doesn't enable
them by default, specify the option enabling EH there. <br>
It is also helpful to specify an option turning warnings into errors
here to get most reliable configuration ( For example, warnings could be
like that : <i>"Warning: namespaces are mostly broken in this
release"</i>, and they're indeed broken. ).</p>
<p>In case you are not able to run configure, you might have to know
internal STLport macros describing compiler features/bugs
Please refer to the <a href="configure.html">Configuration Manual</a> for the values.
</p>
<h3>Modifying the configuration engine</h3>
<p>Don't edit the "configure" script directly, use <b>config/configure.in</b>
source + <b>GNU autoconf</b> instead.</p>
