compile chapter 12 for Mac OSX Mountain Lion?

[bsabiston]

For chapter 12, about distance fields, I want to compile the demo for a mac.

I try 'make' on a mac running 10.8.2, and it says

bob$ make
Usage: make Win32 | Linux | MacOSX | clean | distclean
bob$ make MacOSX
./bundle.sh contourdemo
make: ./bundle.sh: No such file or directory

It is probably something extremely simple but what do I need to do?
Thanks!

My workaround for that was just to comment that line out. I figured that file never made it into the git branch as I also don't have that file after cloning.

I encountered another problem during the compilation:

ld: can't open output file for writing: contourdemo.app/Contents/MacOS/contourdemo, errno=2 for architecture x86_64

And I solved it by manually creating the directories contourdemo.app/Contents/MacOS/

After that I was able to compile and run the sample code.

I was just thinking I would like to go back and get this working. I commented out that line but I am getting "ld: library not found for -lglfw".

The file 'libglfw.a' is in the demo folder, but I guess it doesn't see it? Is that some environment variable problem or something? Anyone know? Thanks!

Yes, it can't find it. You can try bringing it over to your current directory.

It is in the current directory, 'demo'. And I checked my .bash_profile and './' is the last thing in my PATH. That is the only thing I know to check, I'm not very fluent with my UNIX.

OK -- I added "-L." to the gcc compile line in the Makefile. That got it to see the library. Unfortunately the library provided I think is not for Mac. So I went and downloaded GLFW and compiled it, which seemed to work. But when I put the new libglfw.a in the directory and compile, I get this:

Undefined symbols for architecture x86_64:
"_IOCreatePlugInInterfaceForService", referenced from:
__glfwInitJoysticks in libglfw.a(cocoa_joystick.o)
"_IOIteratorNext", referenced from:
__glfwInitJoysticks in libglfw.a(cocoa_joystick.o)
"_IOMasterPort", referenced from:
__glfwInitJoysticks in libglfw.a(cocoa_joystick.o)
"_IORegistryEntryCreateCFProperties", referenced from:
__glfwInitJoysticks in libglfw.a(cocoa_joystick.o)
"_IOServiceGetMatchingServices", referenced from:

"_IOServiceMatching", referenced from:
__glfwInitJoysticks in libglfw.a(cocoa_joystick.o)
ld: symbol(s) not found for architecture x86_64

So that is weird. Do you know what would cause that? It seems like a problem maybe with the GLFW than this project.

OK! I needed to add "-framework IOKit" to the end of the gcc line also. Finally I get the same error as @csanta!
I followed his directions about creating the directories. And ... FINALLY! The thing compiles.

And it works! Only it didn't work by double-clicking the 'app', as you might expect. From the terminal you have to go to the inner directory contour demo.app/Contents/MacOS and run 'contourdemo'.

I can't believe it! It works. Hope this lengthy account helps anyone else wanting to run this on Mac in 2013.
