[cfe-dev] [libcxx] compilation problems with 'long long'

[Lenny Maiorani]

Hello,

I am trying to switch my project (based on FreeBSD7.3) to compile using Clang with the modern libc++. In order to do this, I need to get libc++ compiled. However there are a few problems. I am using the Clang from TOT which was built with GCC 4.2.1.

Below is an excerpt from the failed compilation. What I am doing wrong here?

Thanks,
-Lenny
