iproute2-tc compilation problems

Hi,

I want to use iproute2/tc to access NetEm
(http://linux-net.osdl.org/index.php/Netem). However, my linux distro
Mandrake LE 2005 ships with an older version of 'tc' which doesnot
support the netem commands.

I am trying to compile the latest version of iproute2 for 2.6.13.1.
However, I get an error with the emp_ematch.y file from bison. The
error message is the following:

make[1]: Entering directory `/home/kkmehra/sw/iproute2-051007/tc'
bison -d -t -v -o emp_ematch.yacc.c emp_ematch.y
"emp_ematch.y", line 9: junk after `%%' in definition section
make[1]: *** [emp_ematch.yacc.c] Error 1
make[1]: Leaving directory `/home/kkmehra/sw/iproute2-051007/tc'

Due to this error tc binary is not generated. I am using the latest
version of bison. Has anybody else encountered this?

Do we have a binary for tc with netem support I could download and use?


uname -a:
Linux cs-st-214.cse.iitkgp.ernet.in 2.6.13.1 #2 Wed Oct 19 18:12:19 EDT
2005 i686 Intel(R) Pentium(R) 4 CPU 1.40GHz unknown GNU/Linux

I am using iproute2-051007.

Pls help,

Krishna

Lots of people have encountered this. It is a problem with the bison
version. Most people are installing either an older or a newer bison,
and the most success seems to be with the older.

Set your newsreader to access news.gmane.org and subscribe NG
gmane.linux.network.routing
then have a look at the postings/threads during the last week or two
by Stephen Hemminger (which I may have misspelled). He is the
maintainer of IPROUTE2.
