Related to issue #354

@grigorov : currently it compiles with:

CC=gcc CXX=g++ time gmake -f Makefile.BSD

It also run fine, but I could run much testing yet

Hi, Clang support is not ready? Only gcc??

[renecannao]

Hi, Clang is currently not ready, only gcc .
The difficulty I had in supporting both is in the way they link against c++ libraries . gcc/g++ links against libstdc++ , while clang links against libc++ .
If you specifically needs clang , I can work on it. Please let me know

Commiters freebsd port, not happy dependecy GCC, he can compile default C/C++ compiler (clang).
Now i creating patch files for freebsd port. Compile under clang is not compile, compile under gcc - ok. I see in ubuntu/centos a have clang too. Maybee, can you support clang ? Under fedore 23 - i have clang 3.7.0, on freebsd - clang 3.4.1

[renecannao]

I understand.
Ok, I will make it work on clang too. Please give me few days to work on it

[grigorov]

Not ok? many problems?

Hi Aleks,
Sorry, I didn't invest time in this yet, my apologize for the delay.
Is it possible for you to extensively test ProxySQL compiled with gcc to make sure it works as expected, before compiling with clang ?
Of course I want to support clang, but I think is better to make sure ProxySQL works on FreeBSD with the minimum amount of changes.
Thanks

[grigorov]

Ok, not problem. i use gcc.

@grigorov : let's continue the support for FreeBSD on pull #448 .
