[lldb-dev] How to compile lldb?

[Arne Schmitz]

Hi Vince,

thanks for the response. I am set on Debian Stable, and cannot use a 
different system. As I said, I already build clang snapshot, and libcxx 
snapshot. Plus I am already building lldb using said clang. But now I 
just need to tell the build system to use the libcxx I have just built 
as well. How can I do this?

Best regards,

Arne
