Hello,
I have some difficulties building the pass specified in
lib/Transform/Hello.cpp.
I use LLVM 3.6.0 built by CMake. The system is on Mac OS 10.9.
As required by the documentation of LLVM 3.6,
*http://llvm.org/releases/3.6.0/docs/WritingAnLLVMPass.html#quick-start-writing-hello-world
<http://llvm.org/releases/3.6.0/docs/WritingAnLLVMPass.html#quick-start-writing-hello-world>*I
put the CMake project of 'Hello pass' outside the source tree. Its
structure is as follows:
*<root_of_Hello_project>*
*├── CMakeLists.txt└── Hello (directory) ├── CMakeLists.txt ├──
Hello.cpp └── _build ( directory)*
...
I use these command lines to compile the pass:
*$ cd <root_of_Hello_project>/Hello/_build$ cmake
-DLLVM_DIR=<path>/share/llvm/cmake/ ../../*
*$ make*
where the <path> above is where I built the whole LLVM using CMake.
I get strange error message

Any idea to fix this? Thanks in advance.
