SDL2 Window lacking window bar
<p><a href="https://i.stack.imgur.com/UpYBu.png" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/UpYBu.png" alt=""></a></p>

<p>I'm trying to build an SDL2 app on OSX El Capitan, and I am running into an issue where the window dressing is not appearing. Things like the exit button and the resizing bar are not appearing. I've compiled on Windows and it all works fine there.</p>

<p>To make it a bit easier this link to Lazy Foo's tutorial replicates the issue: <a href="http://lazyfoo.net/tutorials/SDL/01_hello_SDL/index2.php" rel="nofollow noreferrer">http://lazyfoo.net/tutorials/SDL/01_hello_SDL/index2.php</a></p>

<p>My make file is pretty simple (I've stolen it off his website as well)</p>

<pre><code>COMPILER_FLAGS = -w

LINKER_FLAGS = -framework SDL2

#OBJS specifies which files to compile as part of the project
OBJS = main.c 
#CC specifies which compiler we're using
CC = g++

OBJ_NAME = main
#This is the target that compiles our executable
all : $(OBJS)
    $(CC) $(OBJS) $(INCLUDE_PATHS) $(LIBRARY_PATHS) $(COMPILER_FLAGS) $(LINKER_FLAGS) -o $(OBJ_NAME)
</code></pre>

<p>If anyone knows what I am doing wrong, I'd love to find out.</p>

<p>UPDATE: I pulled out an old laptop, fresh installed to El Capitan and it is having the same issue based on the Lazy Foo code.</p>

<p>UPDATE:</p>
