Re: [LARTC] Re: [LARTC} how can I compile tc

[John Baker <johnnyb@marlboro.edu>]

The story here is that I'm am using instructions my predecessor left for 
building a packet shapeing firewall and trying to update them for a new 
box that needs some drivers in the newer kernel version. (I can go back, 
use older versions and manually insert stuff but it makes more sense to 
try the latest stuff first)

I need to build tc because it needs to be patched with 
esfq-2.6.20/esfq-iproute2.patch.

So I built the Linux 2.6.20.3 with the necessary patches and left it in 
/usr/src/linux-2.6.20.3 with a /usr/src/linux symlink pointing to it. I 
didn't do anything after setting it up.

The git version unfortunatly won't compile either. I get this:

../include/linux/types.h:166: error: syntax error before ‘__kernel_daddr_t’
../include/linux/types.h:166: warning: no semicolon at end of struct or 
union
../include/linux/types.h:167: warning: type defaults to ‘int’ in 
declaration of ‘f_tinode’
../include/linux/types.h:167: warning: data definition has no type or 
storage class
../include/linux/types.h:170: error: syntax error before ‘}’ token
make[1]: *** [ll_map.o] Error 1
make[1]: Leaving directory `/usr/src/iproute2/lib'
make: *** [all] Error 2

I'm going to see if I can get iproute 2.6.19 working with this. It 
seemed to compile once but without the proper patches. If not, I'll have 
to move back to the 2.6.15 versions that are already prove.

Unless you have some other suggestion for hte above error.

thanks for you help either way.
