To do this, issue the +command ‘<samp>set language <var>lang</var></samp>’, where <var>lang</var> is the name of +a language, such as +<code>c</code> or <code>modula-2</code>. +For a list of the supported languages, type ‘<samp>set language</samp>’. +</p> +<p>Setting the language manually prevents <small>GDB</small> from updating the working +language automatically. This can lead to confusion if you try +to debug a program when the working language is not the same as the +source language, when an expression is acceptable to both +languages—but means different things. For instance, if the current +source file were written in C, and <small>GDB</small> was parsing Modula-2, a +command such as: +</p> +<div class="smallexample"> +<pre class="smallexample">print a = b + c +</pre></div> + +<p>might not have the effect you intended. In C, this means to add +<code>b</code> and <code>c</code> and place the result in <code>a</code>. The result +printed would be the value of <code>a</code>. In Modula-2, this means to compare +<code>a</code> to the result of <code>b+c</code>, yielding a <code>BOOLEAN</code> value. +</p> + + + +</body> +</html> |
