You can use the +<code>set language</code> command for either purpose. On startup, <small>GDB</small> +defaults to setting the language automatically. The working language is +used to determine how expressions you type are interpreted, how values +are printed, etc. +</p> +<p>In addition to the working language, every source file that +<small>GDB</small> knows about has its own working language. For some object +file formats, the compiler might indicate which language a particular +source file is in. However, most of the time <small>GDB</small> infers the +language from the name of the file. The language of a source file +controls whether C<tt>++</tt> names are demangled—this way <code>backtrace</code> can +show each frame appropriately for its own language. There is no way to +set the language of a source file from within <small>GDB</small>, but you can +set the language associated with a filename extension. See <a href="Show.html#Show">Displaying the Language</a>. +</p> +<p>This is most commonly a problem when you use a program, such +as <code>cfront</code> or <code>f2c</code>, that generates C but is written in +another language. In that case, make the +program use <code>#line</code> directives in its C output; that way +<small>GDB</small> will know the correct language of the source code of the original +program, and will display that source code, not the generated C code. +</p> +<table class="menu" border="0" cellspacing="0"> +<tr><td align="left" valign="top">• <a href="Filenames.html#Filenames" accesskey="1">Filenames</a>:</td><td> </td><td align="left" valign="top">Filename extensions and languages. +</td></tr> +<tr><td align="left" valign="top">• <a href="Manually.html#Manually" accesskey="2">Manually</a>:</td><td> </td><td align="left" valign="top">Setting the working language manually +</td></tr> +<tr><td align="left" valign="top">• <a href="Automatically.html#Automatically" accesskey="3">Automatically</a>:</td><td> </td><td align="left" valign="top">Having <small>GDB</small> infer the source language +</td></tr> +</table> + +<hr> +<div class="header"> +<p> +Next: <a href="Show.html#Show" accesskey="n" rel="next">Show</a>, Up: <a href="Languages.html#Languages" accesskey="u" rel="up">Languages</a> [<a href="index.html#SEC_Contents" title="Table of contents" rel="contents">Contents</a>][<a href="Concept-Index.html#Concept-Index" title="Index" rel="index">Index</a>]</p> +</div> + + + +</body> +</html> |
