Re: [mpls-linux-general] Utility compilation problem

[James R. L. <jl...@mi...>]

Did you apply the kernel patch?  If so, then most likely you are running
on a linux distribution that mucks with your include files.

What you should have:

/usr/src/linux-2.4.0/ is your kernel source with MPLS patch applied
/usr/src/linux is a symbolic link to /usr/src/linux-2.4.0/
/usr/include/linux is a symbolic link to /usr/src/linux/include/linux/
/usr/include/asm is a symbolic link to /usr/src/linux/include/asm

Once you have the correct symbolic links, then make sure to configure the
kernel with MPLS support.  THEN finally you can compile the utilities :-)

I know, it's a lot of work just to compile a utility....
