Unlike C/C++ compilers
|
|
||||||
and many other analysis tools, it doesn't detect syntax errors. Cppcheck
|
|
||||||
only detects the types of bugs that the compilers normally fail to detect.
|
|
||||||
The goal is no false positives.</p><p>Supported code and platforms:</p><div class="itemizedlist"><ul class="itemizedlist" type="disc"><li class="listitem"><p>You can check non-standard code that includes various compiler
|
|
||||||
extensions, inline assembly code, etc.</p></li><li class="listitem"><p>Cppcheck should be compilable by any C++ compiler that handles
|
|
||||||
the latest C++ standard.</p></li><li class="listitem"><p>Cppcheck should work on any platform that has sufficient cpu and
|
|
||||||
memory.</p></li></ul></div><p>Accuracy</p><p>Please understand that there are limits of Cppcheck. Cppcheck is
|
|
||||||
rarely wrong about reported errors. But there are many bugs that it
|
|
||||||
doesn't detect.</p><p>You will find more bugs in your software by testing your software
|
|
||||||
carefully, than by using Cppcheck. You will find more bugs in your
|
|
||||||
software by instrumenting your software, than by using Cppcheck. But
|
|
||||||
Cppcheck can still detect some of the bugs that you miss when testing and
|
|
||||||
instrumenting your software.</p></div><div class="navfooter"><hr><table width="100%" summary="Navigation footer"><tr><td width="40%" align="left"><a accesskey="p" href="index.html">Prev</a> </td><td width="20%" align="center"> </td><td width="40%" align="right"> <a accesskey="n" href="ch02.html">Next</a></td></tr><tr><td width="40%" align="left" valign="top">Cppcheck 1.44 </td><td width="20%" align="center"><a accesskey="h" href="index.html">Home</a></td><td width="40%" align="right" valign="top"> Chapter 2.

like this can be used:</p><pre class="programlisting">cppcheck -DDEBUG=1 -D__cplusplus path</pre><p>An alternative for -D is to use #error.</p><pre class="programlisting">#if LIB_VERSION <= 3
