| <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. |
