That is what I don't understand. This symbol is defined in Dominators.h, which I include in my file. I don't understand why I am getting this error. Here is my opt command, "opt -load LLVMMyDomPass.dylib -mdp < test.bc > test.d.bc" George On Tue, Aug 21, 2012 at 3:25 AM, Duncan Sands <baldrick at free.fr> wrote: > Hi George, > > ... > > dyld: lazy symbol binding failed: Symbol not found: > > __ZN4llvm17DominatorTreeBaseINS_10BasicBlockEE11getRootNodeE...

Hi Guys, I am using the Postdom pass and I would like to get the root of the tree. However, everytime I try to get the root, I get a segfault. I don't know why the environment can't find DominatorTreeBase. Below is the code that generates the Segfault. In my .h file I include Dominators.h PDT.getRootNode(); //PDT is a reference to a PostDominatorTree dyld: lazy symbol binding

I would try to compile LLVM with --enable-shared (autoconf) or BUILD_SHARED_LIBS (cmake). If this works, the dead code elimination is probably the problem....
