Im having a little problem compiling, its fine right up untill i get to:

gmake[3]: *** [main.a] Error 1
gmake[2]: *** [main.a] Error 2


And i cant seam to get past there. Since i dont know what i am doing 
with ar, i was hoping someone else might and could let know what flags 
i needed so i could add them to the Makerules file. Thanks for your 
help.
