programming linux games

Hi, I downloaded the plg book from here

http://isengard.overcode.net/~overcode/writing/plg/

 

anyway looks like a good book and i will be able to get a hardcopy here in New Zealand, it will just take a while to get here.

 

Has anyone gotten the example game to compile in mandrake 9.0?

I have looked at all the include files needed and i seem to have them all, but i can't get any examples with sound to work.

 

heres console output of when i try to compile something with sound:

After looking around i discovered that libsndfile's api has changed a bit, some of the functions have be dropped and replaced with new functions.

 

So either i have to revert back to an older libsndfile if i can find one that works or change the source code to reflect the changes in the api (and i am a c n00b), or contact the author and see if i can get him too change some source code for me.

 

Oh well joys to be me

 

Oh yes i got the hardcopy for this book, it was in a decent bookstore, i was amazed to see it there though.

Got it working by removing the newer version on libsndfile and installing an older one from source.

 

Yay
