[LLVMdev] LLVM Cmake module?

[Eli Gottlieb]

After I actually get everything compiling, install the library, and load 
it from my Java program, I get the following:
> Exception in thread "main" java.lang.UnsatisfiedLinkError: 
> /usr/lib/libjllvm.so: /usr/lib/libjllvm.so: undefined symbol: 
> _ZTVN10__cxxabiv120__si_class_type_infoE
If I have to guess, this means that the CMake stuff given is linking to 
the C++ libraries of LLVM when I wanted them linking to the C bindings.  
Any ideas?  I definitely included the headers for the C bindings only.
