If you have the X11 SDK installed on Mac OS X, you'll build with X11 support, but the Makefile doesn't build anything but the Cocoa testnative code for Mac OS X, which is fine, but then testnative fails to link because testnative.h enables the X11 support based on the SDL config header.
Building the testnativex11.c code on Mac OS X doesn't work because you need to explicitly link with "-L/usr/X11/lib -lX11" if this code is enabled, but you can't link with that by default because the X11 SDK might be missing.
So this needs a little configure magic to do the right thing (or forcibly disabling X11 support on Mac OS X in testnative.h).
These are test programs for the SDL library:
checkkeys Watch the key events to check the keyboard
loopwave Audio test -- loop playing a WAV file
testaudioinfo Lists audio device capabilities
testcdrom Sample audio CD control program
testerror Tests multi-threaded error handling
testfile Tests RWops layer
testgl2 A very simple example of using OpenGL with SDL
testhread Hacked up test of multi-threading
testiconv Tests international string conversion
testjoystick List joysticks and watch joystick events
testkeys List the available keyboard keys
testloadso Tests the loadable library layer
testlock Hacked up test of multi-threading and locking
testmultiaudio Tests using several audio devices
testoverlay2 Tests the overlay flickering/scaling during playback.
testpalette Tests palette color cycling
testplatform Tests types, endianness and cpu capabilities
testsem Tests SDL's semaphore implementation
testshape Tests shaped windows
testsprite2 Example of fast sprite movement on the screen
testtimer Test the timer facilities
testver Check the version and dynamic loading and endianness
testwm2 Test window manager -- title, icon, events
torturethread Simple test for thread creation/destruction
