3.3 Environment variables
</H1>

<P>
SDCC recognizes the following environment variables:

<UL>
<LI>[<B>SDCC_LEAVE_SIGNALS<A NAME="1259"></A></B>] SDCC
installs a signal handler<A NAME="1260"></A> to be able to delete
temporary files after an user break (&#94;C) or an exception.
If this environment variable is set, SDCC won't install the signal
handler in order to be able to debug SDCC.
</LI>
<LI>[<B>TMP,&nbsp;TEMP,&nbsp;TMPDIR<A NAME="1262"></A></B>] Path,
where temporary files will be created. The order of the variables
is the search order. In a standard *nix environment these variables
are not set, and there's no need to set them. On Windows it's recommended
to set one of them.
</LI>
<LI>[<B>SDCC_HOME<A NAME="1264"></A></B>] Path,
see section <A HREF="node12.html#sub:Install-paths">2.2</A>&nbsp;'' Install Paths''.
</LI>
<LI>[<B>SDCC_INCLUDE<A NAME="1266"></A></B>] Path,
see section <A HREF="node13.html#sub:Search-Paths">2.3</A>&nbsp;''Search Paths''.
</LI>
<LI>[<B>SDCC_LIB<A NAME="1268"></A></B>] Path,
see section <A HREF="node13.html#sub:Search-Paths">2.3</A>&nbsp;''Search Paths''..
</LI>
</UL>There are some more environment variables recognized by SDCC, but
these are mainly used for debugging purposes. They can change or disappear
very quickly, and will never be documented<A NAME="tex2html30"
  HREF="footnode.html#foot5704"><SUP>3.2</SUP></A><A NAME="1272"></A>.
