Building on OSX with brew requires some extra flags

[jasonwatkinspdx]

Building on OSX for me needed some extra flags in the SConstruct.

Error:

>  scons
scons: Reading SConscript files ...
scons: done reading SConscript files.
scons: Building targets ...
clang++ -o src/Sound_Queue.o -c -O3 -march=native -std=c++11 -Wno-unused-value -Isrc src/Sound_Queue.cpp

#include <SDL2/SDL.h>
         ^
1 error generated.
scons: *** [src/Sound_Queue.o] Error 1
scons: building terminated because of errors.

I get a successful build with:

-flags = ['-O3', '-march=native', '-std=c++11']
+flags = ['-O3', '-march=native', '-std=c++11', '-I/usr/local/include', '-L/usr/local/lib']

 env = Environment(ENV       = environ,
                   CXX       = 'clang++',

But it also has a bunch of build spam like:

clang: warning: argument unused during compilation: '-L/usr/local/lib'

for every unit that doesn't need SDL. I'm an ignoramus when it comes to scons so posting an issue vs a pull request in the hope someone else knows how to resolve that trivially.

I just cloned and built on OS X (sierra) without any issue. Not sure if it makes a difference or not but I had just done the brew install scons sdl2 sdl2_image sdl2_ttf step and then immediately scons. The versions it installed are on this gist. The scons build output there is totally clean and I didn't have to touch the Sconsfile.

I have the same issue with Jason. After I follow Jason's method, I also encountered that the library is not included.

No issues with macOS Sierra and homebrew here.

I can't reproduce this. First thing I can think of: do you have the Xcode CLI tools installed?

[michaelclarkjr]

I got the same problem and fixed it with the above flags. For those with no issues, it could be an OS version thing (I'm running El Cap, not Sierra).

[MainReturnZero]

Xcode CLI is installed in my system.

[AndreaOrru]

I'll leave this open for now. I'll try to test in on other Mac machines and see if I can reproduce it.

I also don't have a problem building latest version on Sierra 10.12.5.

[AndreaOrru]

I'm gonna assume this works now. Let me know if it doesn't.
