<h4 class="subsection">15.1.3 Having <span class="sc">gdb</span> Infer the Source Language</h4>
|
||
|
|
|
||
|
|
<p>To have <span class="sc">gdb</span> set the working language automatically, use
|
||
|
|
‘<samp><span class="samp">set language local</span></samp>’ or ‘<samp><span class="samp">set language auto</span></samp>’. <span class="sc">gdb</span>
|
||
|
|
then infers the working language. That is, when your program stops in a
|
||
|
|
frame (usually by encountering a breakpoint), <span class="sc">gdb</span> sets the
|
||
|
|
working language to the language recorded for the function in that
|
||
|
|
frame. If the language for a frame is unknown (that is, if the function
|
||
|
|
or block corresponding to the frame was defined in a source file that
|
||
|
|
does not have a recognized extension), the current working language is
|
||
|
|
not changed, and <span class="sc">gdb</span> issues a warning.
|
||
|
|
|
||
|
|
<p>This may not seem necessary for most programs, which are written
|
||
|
|
entirely in one source language. However, program modules and libraries
|
||
|
|
written in one source language can be used by a main program written in
|
||
|
|
a different source language. Using ‘<samp><span class="samp">set language auto</span></samp>’ in this
|
||
|
|
case frees you from having to set the working language manually.
