Copile error "error: 'log2' is not a member of 'std'" on G5 with MacOS 10.5.8

[maciejmiklas]

My setup: G5 Dual Core with MacOS 10.5.8, configuration used for build: G5.mozcfg
I followed the build instructions, and as far as I can tell, everything was successful.
The compilation breaks with an error:
error: 'log2' is not a member of 'std'

GCC 4.8 should support C99, but I wonder if this function is implemented for PPC.

Is this a bug, or am I doing something wrong?

Here is the full log:

This is known, and is an issue with the 10.5 SDK. Please see #498

Thank you - replacing std::log2 with log2 solved the issue, and the compilation was successful.
