Hello,
I have installed SDL on my mac osx from command line and am running one
of the first test programs in the documentation. I am using the compile
command:
gcc -o test test.c sdl-config --cflags --libs,
which is on the linux FAQ page (no compilation instructions on the mac
osx FAQ page),
and I get the following error message:
cc1: unrecognized option -fcflags' cc1: unrecognized option-flibs’
I don’t understand how to fix this because I don’t know where these
libraries are. I have checked in all of the SDL libraries with no luck.
I also have sdl-config in the source code’s directory so that’s not the
problem. Any assistance would be greatly appreciated.
Thank you,
Daniel Roberts

You forgot the backticks. sdl-config is a shell script that spits out
the compilation and linker flags used when SDL was compiled. What you
should be typing is something like:
gcc -o test test.c sdl-config --cflags --libs
However, in my experience, Xcode or Project Builder would make your
life a whole lot easier than doing this crap by hand or with Makefiles.

When you pass an unrecognized long option (and option
beginning with --) Apple’s GCC turns that into a -f
option. Therefore, --foo becomes -ffoo.
sdl-config is a program that comes with unix style SDL
that will print out useful things to help you compile
and link your SDL application. On my system, this
happens:
$ sdl-config --cflags --libs
-I/opt/local/include/SDL -D_THREAD_SAFE
-L/opt/local/lib -lSDLmain -lSDL -framework Cocoa
-framework OpenGL
These are options that you can pass to GCC. In bash,
enclosing a string inbetween back-ticks (`) executes
that string as a command, and then replaces it with
the output of that command. So for instance:
$ echo `echo HI`
HI
$ echo `HI`
bash: HI: command not found
In short, you forgot to use the backtick. Compile like
so:
gcc -o test test.c sdl-config --cflags --libs
In the future, you may want to look at not linking to
the OpenGL library if you don’t need it.__________________________________
