[cfe-dev] undefined reference to `vtable for clang::ASTConsumer' LLVM 3.4.2 Release+Asserts build

[Bogdan Tabacaru]

Hi everyone,

I am using CygWin 1.7.31 32-bit. 

I have downloaded llvm 3.4.2 with clang, compiler-rt and extra clang tools.

I configured llvm and clang in a "build"-directory with the default options (i.e., ../configure).
I built everything with the default configuration options and using REQUIRES_RTTI=1 (i.e., make REQUIRES_RTTI=1).
Afterwards, I tried to build the PrintFunctionNames example from ~/llvm/build/tools/clang/examples/PrintFunctionNames. (i.e., make REQUIRES_RTTI=1 BUILD_EXAMPLES=1).

It compiles successfully, but the linking fails.

$ cd ~/llvm-3.4.2.src/build/tools/clang/examples/PrintFunctionNames
$ make REQUIRES_RTTI=1 BUILD_EXAMPLES=1

I have even tried this with the -fno-rtti flag set. And I received the same error message.
I also tried it with the ENABLE_CXX11=1. It still does not work.

Thanks a lot for your help.

Kind Regards,
Bogdan

P.S. I am experiencing the same problem with llvm 3.5.
