Hi,
I am trying to add a pass inn LLVM, and I actually want to add it in
source code, not just directly into object code.
For that I included the lines in my file MyAna.cpp
(llvm-2.6/lib/ana/MyAna.cpp)
char MyAna::ID = 0;
static RegisterPass<MyAna> X("my-aa","My Analysis");
static RegisterAnalysisGroup<AliasAnalysis> Y(X);
ModulePass *llvm::createMyAnaPass() { return new MyAna(); }
I also included createMyAnaPass() in Passes.h and LinkAllPasses.h
But when I do make I get the following error :
/home/ambika/llvm/llvm-obj/tools/opt/Release/opt.o: In function `global
constructors keyed to opt.cpp':
opt.cpp:(.text+0x1e89): undefined reference to `llvm::createMyAnaPass()'
Am I missing out something.
Please help me.
thanks and regards,
Ambika

Thanks that helped me out. But now I am facing one more problem. It says : ‘llvm::ModulePass* llvm::createMyAnaPass()’ should have been declared inside ‘llvm’ but I can find no place to declare it. Where should I do it.
