<p class="MsoNormal"><span lang="EN-US">Hi,<o:p></o:p></span></p>
<p class="MsoNormal"><span lang="EN-US"><o:p> </o:p></span></p>
<p class="MsoNormal"><span lang="EN-US">Has anyone succeeded in building llvm on AIX?<o:p></o:p></span></p>
<p class="MsoNormal"><span lang="EN-US"><o:p> </o:p></span></p>
<p class="MsoNormal"><span lang="EN-US">Currently I am investigating several tools for code analyses and I came upon Clang. We at CCV run our core business applications on RS6000/AIX. At our department we develop those applications.<o:p></o:p></span></p>
<p class="MsoNormal"><span lang="EN-US">The reviews on clang look very promising. I was able to build and run it on Linux (SuSE 12.1) without any problems. I tested it with valgrind sources and was impressed by the issues it found.<o:p></o:p></span></p>
<p class="MsoNormal"><span lang="EN-US"><o:p> </o:p></span></p>
<p class="MsoNormal"><span lang="EN-US">Building it on AIX is a total disaster however. I had to add some code (added dladdr() function), change Makefiles etc. but that wasn’t to much of an issue.<o:p></o:p></span></p>
<p class="MsoNormal"><span lang="EN-US">I first tried to build it using cmake<o:p></o:p></span></p>
<p class="MsoNormal"><span lang="EN-US">That stopped at the point of not being able to find
</span><b><span lang="EN-US" style="font-family:"Courier New"">mach-o/dyld.h</span></b><span lang="EN-US">. After fixing that, lots of 'undeclared' (symbols), 'unknown type name' and 'dereferencing pointer to incomplete type' errors came up.<o:p></o:p></span></p>
<p class="MsoNormal"><span lang="EN-US"><o:p> </o:p></span></p>
<p class="MsoNormal"><span lang="EN-US">After that, I made a new build directory and followed the 'Getting Started with LLVM' instructions. That is, using configure.
<o:p></o:p></span></p>
<p class="MsoNormal"><span lang="EN-US">Running make returned the following errors:<o:p></o:p></span></p>

<p class="MsoNormal"><span lang="EN-US">I’ve searched the internet and tried al suggestions that were given for this error message. None of them, however, in combination with llvm. Nothing worked. I really would like to use clang, but I am desperate on how
to continue. I tried cross compiling it on the linux machine, but that wasn’t a straight forward action either. At least not for me. I started with llvm version 3.1 and tried 3.0. Alas, no luck.<o:p></o:p></span></p>
