Hi, Just to report that when I tried to compile some code with a NoFolder given as template arg to my IRBuilder, the compiler complained with: In file included from lang_3-llvm.cxx:33: /usr/lib/llvm-2.8/include/llvm/Support/IRBuilder.h: In member function ‘llvm::Value* llvm::IRBuilder<preserveNames, T, Inserter>::CreateFNeg (llvm::Value*, const llvm::Twine&) [with bool preserveNames = true, T = llvm::NoFolder, Inserter = llvm::IRBuilderDefaultInserter<true>]’: ... I just added Value *CreateFNeg(Constant *C) const { return BinaryOperator::CreateFNeg(C); } amongst...

Thank you very much for your reply. However, my question is not completely solved. I svned the latest version of the llvm. After I open in the visual studio 2005, the building errors are still there and there was not any .exe executable file output. I set the Fibonacci project under the solution as my startup project and issue the debug-run command. However, the vs 2005 just prompted me that the
