When I build LLVM first, however, I get told that it can't find llvm-gcc and that it therefore won't build properly. And, true to form, when I ignore the warning from ./configure and proceed anyway it chokes.<BR>

Despite the warning a make seems to work and a make install seems to put things into sane places. So I run a configure, then a make in the gcc4 source directory. It builds fine until I get this:<BR>

This is where I'm stuck, now. It's looking for some kind of library made by gcc's build that obviously failed somewhere earlier in the millions of lines of messages spewed out by GCC's build system. Given the profusion of -I and such statements pointing into the llvm source code, I'm pretty sure it's something in the llvm build that's failed on me. (Of course after poring over these millions of lines of code I could be missing something really obvious, so I'm not sure here at all.)<BR>

I'll be building both, but probably using 4 most often because most of what I'd be using it for is C code anyway. I can wait for 2.0 to get C++.<BR>

This is the one I was trying with the results you can see above when building LLVM without an llvm-gcc.<BR>

This would be the source that has conflicting dependencies. GettingStarted tells you you need an llvm-gcc to build llvm. But the pointer to bootstrapping llvm-gcc says you need a functioning llvm.<BR>
