[LLVMdev] LLVM Type Int32Ty Problems & LLVMContextImpl.h Problems

[Jin Huang]

Hello! I'm newer to LLVM development . I'm trying to use AllocaInst class
to construct an instruction ,  I wrote like this:

    AllocaInst *alloc = new AllocaInst(llvm::Int32Ty, 0, "indexLoc",i);

but it return the error:

 error: use of undeclared identifier 'llvm::Int32Ty'
                  AllocaInst *alloc = new AllocaInst(Int32Ty, 0,
"indexLoc",i);

I found that the Int32Ty is defined in the LLVMContextImpl.h , but I can
not find it in the llvm include directory.

I installed llvm in  "/usr/local/llvm"  but there is no "LLVMContextImpl.h"
in /usr/local/llvm/include/llvm/IR (LLVMContext.h exists)

Does this mean that the llvm is not installed correctly? What should I do
to fix it? Thank you~
