[CMake] Make errors when running ./bootstrap in Ubuntu 12.04

[Juan E. Sanchez]

The original poster is using Ubuntu 12.04, so a precompiled binary might 
not work if it targeted a newer system.  Ubuntu 12.04 is obsolete and no 
longer supported by Canonical and is a huge risk for production systems.

I would suggest the original poster try installing gnu gcc c++ instead 
of clang.

Please see:

Regards,

Juan
