[cfe-dev] Anyone who has built lldb successfully on RHEL 6.x?

I have been trying to build lldbwith the following two approaches:

(I) using llvm/clang 3.3 together with libc++/libc++abi so the build is free of libstdc++:

This is what I used to configure the build:

../llvm/configure --prefix=/usr --enable-optimized --disable-assertions --enable-targets=host-only --enable-cxx11=yes --enable-libcpp=yes --with-extra-ld-options="-lc++abi"

The resulting Release/bin/lldb crashes even for simple things like help x-(

(II) using the bundled GCC 4.4.7

This is what I used to configure the build:

CC=gcc CXX=g++ CXXFLAGS=-std=c++0x ../llvm/configure --prefix=/usr --enable-optimized --disable-assertions --enable-targets=host-only

As a result, the current llvm/clang based C++11 environment on this test machine doesn't have the lldbdebugger ;-( Although so far I have been able to build even the full Boost libraries on this host, not having a matching debugger just doesn't install good feeling.

Any tips are appreciated!
