Please provide more details. This is which Linux version? Which version of glibc? Which distribution? Which gcc? I haven't seen any bug reports about this ever.

We shouldn't include the low-level headers if th at's not absolutely necessary. However, I think we don't need sys/time.h anyway. At least for me it compiles without that include. > which eliminated two errors and left: > > In file included from v4l.c:67: > /usr/include/linux/time.h:9: redefinition of `struct timespec' > /usr/include/linux/time.h:88: redefinition of `struct timeval' > > > Any idea which other include references timespec again? Or just what to do > to get this working? Maybe one of the standard system headers includes sys/time.h? Are you sure that you have the headers that came with glibc in /usr/include/linux? Sometimes /usr/include/linux is a link to /usr/src/linux/include/linux, that causes all sorts of problems when the kernel headers change and is strongly discouraged. Bye, Henning
