Adrian, this is my fedora 2
[EMAIL PROTECTED] 204> uname -a
Linux athlon 2.6.5-1.358custom #5 SMP Fri May 28 09:46:43 CEST 2004 i686 athlon i386 GNU/Linux
and I have never encountered such problems, even on fresh fedora's. Anybody out there that can comment about this problem?
Regards, Luca

hello list, and Luca
i'm running fedora core 2 with kernel 2.6.8.1 compiled by myself, in a build environment adapted for 2.6 only... and i get errors when compiling ntop. see below how to reproduce them and how to patch them.
by default, fedora core 2, even if it comes with a 2.6 kernel, comes with the 2.4 generation's include files.
this can be tested by looking into /usr/include/linux/version.h, which contains:
#define UTS_RELEASE "2.4.20" #define LINUX_VERSION_CODE 132116 #define KERNEL_VERSION(a,b,c) (((a) << 16) + ((b) << 8) + (c))
while the 2.6.8.1 kernel has this version.h : #define UTS_RELEASE "2.6.8.1" #define LINUX_VERSION_CODE 132616 #define KERNEL_VERSION(a,b,c) (((a) << 16) + ((b) << 8) + (c))
this might lead to a number of incompatibilities for programs written for the 2.4 kernel series includes which run under the 2.6 kernel, and i made some alterations to the include files in /usr/include, all of them are links to the include files that come with the kernel. i've compiled apache 2.0.50, squid 2.5stable6, and some other programs, and all are running without any issues so far.
all issues with the compile process are with header files being moved around.
i had to make a modification to the includes file list, the linux 2.6 kernel doesnt include the file net/ethernet.h which i had to copy from the old includes into the new one, to be able to compile programs.
these are the modified includes in /usr/include. I linked directly to the include files in the kernel source tree:
acpi -> /usr/src/linux/include/acpi/ asm -> /usr/src/linux/include/asm-i386/ asm-generic -> /usr/src/linux/include/asm-generic/ linux -> /usr/src/linux/include/linux/ math-emu -> /usr/src/linux/include/math-emu/ media -> /usr/src/linux/include/media/ mtd -> /usr/src/linux/include/mtd/ net -> /usr/src/linux/include/net/ pcmcia -> /usr/src/linux/include/pcmcia/ rxrpc -> /usr/src/linux/include/rxrpc/ scsi -> /usr/src/linux/include/scsi/ sound -> /usr/src/linux/include/sound/ video -> /usr/src/linux/include/video/
i downloaded a fresh cvs source tree today, and the modifications for the 2.6 new includes which allow me to compile ntop on my machine are:
1) in configure.in, and in a few other places (ntop.h) net/if.h should be for 2.6 (or should be added with a build environment test) linux/if.h
2) config.log:/usr/include/netinet/if_ether.h:62:24: net/if_arp.h: No such file or directory config.log:/usr/include/netinet/if_ether.h:62:24: net/if_arp.h: No such file or directory
this is because if_arp.h is no longer in the net/ but in the linux/ section too
3) in config.h HAVE_NETINET_IF_ETHER_H gets undefined by ./configure because the current header file netinet/if_ether.h has a wrong include, net/if_arp.h instead of linux/if_arp.h I edited that include file to correct it. (i'd better submit it to the kernel discussion list too, as a FIXME )
after these tweaks ntop compiles cleanly and runs without issues, so far.
Luca, can you please add a test to the configure script to test which headers is ntop being built with and adjust the build process accordingly ?
these header files might not be the only ones moved between 2.4 and 2.6, but are the ones that gave me the most headaches.
Thankyou, Adrian R.
