Hi all,
I just downloaded and compiled LLVM and I'd like to use the JIT API in
a project that I've got in Xcode. I'm confused because I thought I
could use LLVM like a library, but it seems I can't simply include
some headers and link to lib, as usual. Or can I? I don't see a
framework or dylib file, which I would usually add to my Xcode
project. The /usr/local/lib directory has a bunch of .a files.
This page (http://llvm.org/docs/Projects.html) suggests that I need to
learn about the LLVM build system. If so, why?
I tried simply adding all the .a files in /usr/local/lib, but my
programs fails at:
engine = EngineBuilder(module).setErrorStr(&err).create();
The 'engine' is null, and 'err' is "Interpreter has not
been linked in.".
thanks,
Rob

It's best to supply --enable-shared to configure. This will build you libLLVM-2.9svn.dylib. This is the only library you need to link your app with. Yuri
