Hello All! I can't compile one small software title because of lack <sys/io.h> and inb/outb macros. What sould I do to overcome this obstacle? My linux distro is Fedora 7 if it is matter.They don't exist in user space on non-x86. You have to do things differently. What is your software trying to do ? If it's trying to access a PCI device IO space, you probably want to mmap it in sysfs and write your own accessors with appropriate memory barriers.
All cases where I've seen application software use <sys/io.h>, there was actually a full device driver in the kernel that already exported a high-level interface to user space. If that's the case here, the application should use that instead of sysfs. Arnd <><
