2.6.22: dvb header files break compilation on x86-64

[Gert Vervoort]

Some of the linux/dvb header files include libc header files and break compilation on x86-64 in compat_ioctl.c:


   CC      fs/timerfd.o
   CC      fs/eventfd.o
   CC      fs/compat.o
   CC      fs/compat_ioctl.o
In file included from fs/compat_ioctl.c:111:
include/linux/dvb/audio.h:27:20: error: stdint.h: No such file or directory
In file included from fs/compat_ioctl.c:112:
include/linux/dvb/dmx.h:28:18: error: time.h: No such file or directory
make[1]: *** [fs/compat_ioctl.o] Error 1
make: *** [fs] Error 2
[root@apollo linux-2.6.x]#

According to the line numbers your build is pulling a version of the 
header cleaned for userspace.

Does this happen with a freshly unpacked vanilla 2.6.22 kernel from 
ftp.kernel.org?

Please send the first 50 lines of the file include/linux/dvb/audio.h in 
your kernel sources.

What is the output of "make V==1" for fs/compat_ioctl.o?

Indeed, it seems that these files, in the kernel tree I used with the 
2.6.22 patch, where modified in the past (a diff of 
include/linux/dvb/audio.h between my tree and a fresh tree clearly 
showed the problem).

I replaced my tree with a fresh 2.6.22 tree and it now compiles without 
any problems.
