Re: [AVFS] avfs cvs compile

In case I was not clear, I use kernel 2.6.5 on Slackware 9.1.

Adam was nice enough to write me the following:

Nick Mitchell had posted this a while back.  Should be what you're
looking for:

This is a hack to get AVFS to compile if you get the following errors
 when you try to do so:
 
 /usr/include/linux/time.h:9: error: redefinition of `struct timespec"
 /usr/include/linux/time.h:15: error: redefinition of `struct timeval"
 make[1]: *** [mount.o] Error 1
 
 Hack is edit out the following lines from time.h in /usr/include/linux
 
 #ifndef _STRUCT_TIMESPEC
 #define _STRUCT_TIMESPEC
 struct timespec {
        time_t  tv_sec;         /* seconds */
        long    tv_nsec;        /* nanoseconds */
 };
 #endif /* _STRUCT_TIMESPEC */
 
 struct timeval {
        time_t          tv_sec;         /* seconds */
        suseconds_t     tv_usec;        /* microseconds */
 };
 
 do something like
 
 //#ifndef _STRUCT_TIMESPEC
 //#define _STRUCT_TIMESPEC
 //struct timespec {
 //     time_t  tv_sec;         /* seconds */
 //     long    tv_nsec;        /* nanoseconds */
 //};
 //#endif /* _STRUCT_TIMESPEC */
 
 //struct timeval {
 //     time_t          tv_sec;         /* seconds */
 //     suseconds_t     tv_usec;        /* microseconds */
 //};
 
 Build avfs according to its install instructions.
 Return time.h to its previous, unedited state.
 Once avfs installed ROX has got its icing plus some cherries.
 
 This will stop the header conflicts that are causing AVFS compile to
 drop out.
 
 The probelm is not confined to SUSE 9 or kernel 2.4.21 but is due to
 some libc distributions including the linux header files it was built
 with and the conflicts not being taken care of.
 Hope this saves some other poor sap seveal hours of digging.

I did this, but also found it necessary to comment out the structs timezone,
itimerspec and itimerval at lines 20, 354, and 359 of time.h as well.

After this, compile STILL failed in dispatch.c at line 322 and the following
error output was emitted:

Unfortunately, I believe the significant changes to header structure in the
2.6.x kernel has caused many problems -- not just with dispatch.c!
