Build Problem

[Paulo Marcio]

Hello, i'm using Ubuntu 14.10 trying to compile folly but i got this message error when i call make:

In file included from Bits.cpp:19:0:
./../folly/CpuId.h: In function 'int (* {anonymous}::folly_popcount_ifunc())(unsigned int)':
./../folly/CpuId.h:49:62: error: PIC register clobbered by 'ebx' in 'asm'
     __asm__("cpuid" : "=a"(n) : "a"(0) : "ebx", "edx", "ecx");
                                                              ^

       __asm__("cpuid" : "=c"(f1c_), "=d"(f1d_) : "a"(1) : "ebx");

       __asm__("cpuid" : "=c"(f1c_), "=d"(f1d_) : "a"(1) : "ebx")

I'm using gcc version 4.9 for compilation, followed the steps described on the README file.

Searching on the web i find out that this problems are specifically for i368 architecture, and then i found this post with a possible solution: http://tuxion.com/2010/07/02/clobber-registers.html, i'll try this later when i have time, if someone can give me additional information i'll thank you.
