cross compile tcpdump

Hi there

I'm compiling tcpdump for my Linksys WRT54GL router.
libcap compiles fine but compiling tcpdump gives me a bunch of errors.

I'm dooing this:




tar -xvf libpcap-1.0.0.tar.gz

tar -xvf tcpdump-4.0.0.tar.gz

tar -xvf toolchains.x86.debian.sp1.tar.bz2

apt-get install flex

apt-get install bison

export PATH=~/toolchains/4.1.0-uclibc-0.9.28/bin:$PATH

cd /root/libpcap-1.0.0

CC=mipsel-linux-uclibc-gcc ac_cv_linux_vers=2 ./configure --host=mipsel-linux --with-pcap=linux


cd ../tcpdump-4.0.0

CC=mipsel-linux-uclibc-gcc ac_cv_linux_vers=2 ./configure --host=mipsel-linux --with-pcap=linux

Anyone knows how to sort it out ?

A mipsel package 'tcpdump-3.9.5' is here
The oldest will have best chances to fit.
'libpcap' :
Development files "libpcap0.8-dev" :
> > "Links for tcpdump" :
[tcpdump_4.0.0.orig.tar.gz], [tcpdump_4.0.0-5.debian.tar.gz]
The options used for compiling :
Unpack the "patch" tcpdump_4.0.0-5.debian.tar.gz
and have a look into the file tcpdump-4.0.0/debian/rules
.. and may be use the patches tcpdump-4.0.0/debian/patches
