[llvm-dev] Error: ‘class llvm::PassManager<llvm::Module>’ has no member named ‘add’

 Yes, I did that. Now the error is comming:

error: no matching function for call to ‘llvm::legacy::PassManager::
add(llvm::DataLayout*)’
  PM.add(new DataLayout(td));
                           ^
In file included from main_test.cpp:15:0:
/tmp/llvm/include/llvm/IR/LegacyPassManager.h:55:8: note: candidate:
virtual void llvm::legacy::PassManager::add(llvm::Pass*)
   void add(Pass *P) override;
        ^
/tmp/llvm/include/llvm/IR/LegacyPassManager.h:55:8: note:   no known
conversion for argument 1 from ‘llvm::DataLayout*’ to ‘llvm::Pass*’
