Hi,<div><br></div><div>I think the latest gcc on FreeBSD is 4.6.something, and it also didn't work.

<div><br></div><div>clang on FreeBSD worked fine, even if I only compiled the problematic files on clang (and compiled the rest with g++).</div><div><br></div><div>For compiling with XCode, you don't need any change, it just works (at least in the 4.x versions). Compiling with the makefiles and gcc will give you that error. If you use "make VERBOSE=1", you can see the commands issued and simply substitute clang++ for g++ in the erroneous commands(or you can configure the Makefiles to use clang).</div>

I get this same error (and 17 others like it) compiling on Mac OS/X<br>
in XCode version 3.2.6. gcc --version says 4.2.1 (I assume that's the<br>
gcc XCode is using but can't be sure). uname -a says version is 10.8.0.<br>
<br>
I followed the instructions documented here <a href="http://lldb.llvm.org/build.html" target="_blank">http://lldb.llvm.org/build.html</a><br>
and started with a clean build. This is building just lldb (no llvm/clang)<br>
inside the XCode IDE.<br>
<br>
What's the actual source change to fix this? Can you please send a patch?<br>
<br>
Thanks in advance,<br>
-Dawn<br>
