you can get the CItutorial6.cpp and corresponding makefile at this website<br>
<a href="https://github.com/loarabia/Clang-tutorial" target="_blank">https://github.com/loarabia/Clang-tutorial</a><br>
<<a href="https://github.com/loarabia/Clang-tutorial" target="_blank">https://github.com/loarabia/Clang-tutorial</a>> .<br>
Actually,CIrewriter.cpp,CItutorial1-CItutorial6 would Encounter Problems as<br>
above,but tutorial1-tutorial6 are Running the perfectly.why them happend?<br>
Any help would be appreciated.<br>

the problem will go away. I'm not sure why clang allows the current call, as the interface changed.<br><br>Robert<br><br></div></div>
