[LLVMdev] Porting pass from llvm 3.1 to 3.4

[Diogo Sampaio]

Dear llvmers

I'm trying to port some code that was written for llvm 3.1 to 3.4.2.
I'm having two linking problems and I couldn't find the source of the
problem. Usually it is an error for a virtual method not declared. The
error starts even when changing llvm version from 3.1 to 3.2.

The current line declaring an command line option:
-----
static cl::opt<string> InputFilename(cl::Positional, cl::Required,
cl::desc("<input bitcode file>"), cl::init("-"),
cl::value_desc("filename"));

And the class declaration:
class Ids : public ModulePass {
}
-----
Gives me these linking time errors:


cd /home/sampaio/3.2/ddg/build/tools/dynamic-graph && /usr/bin/cmake
-E cmake_link_script CMakeFiles/cdag_disk.dir/link.txt --verbose=1
/usr/bin/g++-4.6       CMakeFiles/cdag_disk.dir/cdag_disk.cxx.o  -o
