gcc error

mango_1 — Thu, 24 Jul 2003 14:36:15 GMT

hello all! I currently need to compile a program using gcc. however that program outputs an error about
_IOREAD undeclared. I noticed that this is because this is not defined in stdio.h. Is there a work around I could use to still be able to compile the program? Is there a flag or option for this?

thanks for any help! :)

define _IOREAD in stdio.h

see :

or see:

Hello!

Could be that you have coruped headear files
of your gcc or you just need to patch them.
