I didn't get much time to work on it after that. Today, I had a look at it. I included a workaround for that weird marco incompatibility error between LLVM and wxWidgets. I just commented out the line - "#define _(s) wxGetTranslation(wxT(s))" in wx/intl.h and it built successfully.<div>

Thanks John. I verified that and poolalloc builds with LLVM 3.0. I

<div>But llvm-tv build still gives build error. I take it that
llvm-tv is still incompatible with these versions of poolalloc

in lib,include and some 30 odd small files in tools directory.
I'll have a look at the code to sort out the build errors.</div>

The llvm-tv project hasn't been used in a long, long time. In fact,
I don't think anyone has used it or worked on it since LLVM 2.0 was
released back in 2007.<br>
<br>
If you want to update llvm-tv to LLVM 3.0 (or, better yet, LLVM
3.1), that would be cool, but just be aware that it's a significant
project that you'll have to do on your own (the LLVM internal API
has changed *a lot* since llvm-tv was written). I also don't know
how much demand there is for a tool like llvm-tv.<br>
<br>
That said, people on llvm-dev are usually happy to answer questions
on the LLVM 3.1/LLVM mainline API.<div><br>

The perror() function is a Unix/Posix function. The llvm-tv code is
probably assuming that some LLVM header files #includes the
definition of it. This was true in LLVM 1.x; it's not true now.
You'll have to search out and fix all these issues if you work on
llvm-tv.<br>
<br>
As an FYI, I never worked on llvm-tv. I just made the comment about
poolalloc in the case that your primary interest was in
understanding the poolalloc transform.<br>
