#2 make failure: asm/io.h: No such file or directory

[David Bush]

make produces this error on my i386 Kubuntu 7.10 OS:

make[1]: Entering directory `/home/david/sw/LinRadio/linradio-toolkit-0.7/driver'
gcc -c -O2 -Wall -ffast-math -DGNU_SOURCE wrlib/wrio.c -o wrio.o
wrlib/wrio.c:6:22: error: asm/io.h: No such file or directory

Here is the offending code from wrio.c:

#if defined(__linux__) && !defined(__KERNEL__)
# include <stdio.h>
# include <unistd.h>
# include <time.h>
# include <sys/time.h>
# include <asm/io.h>
#endif /* __linux__ && !__KERNEL */

The INSTALL file says Linux 2.2.5 is a minimum requirement, but at the time of this report we're at 2.6.22 for Kubuntu 7.10. Maybe the kernel header files have moved around since then?
