What's wrong with my cross-compiling?

beakmyn · 02-15-2006

Ok, I'm sure with the collective knowledge we can me straightened out on this issue. Dutch is probably getting tired of whining.
I'm attempting to cross-compile and strip kismet_server newcore.

Yeah it's real smart to modify files in another user's directory as root I know it's naughty but I do it any way.

1. Startup laptop
2. root@tty2#SVN ... kismet-newcore to /home/user/
3. root@tty2#cp /home/user/kismet-setup.sh /home/user/kismet-newcore
4. root@tty2#cd /home/user/kismet-newcore
5. root@tty2#chmod 777 kismet-setup.sh
6. root@tty2#cd /home/user/whiterussian/openwrt
7. root@tty2#make menuconfig
8. root@tty2#make
9. root@tty2#cd /home/user/kismet-newcore
10. root@tty2#sh kismet-setup.sh
11. Wait till that's done

Code:

Configuration complete:
Compiling for:         linux-gnu (mipsel)
C++ library:           uclibc
Installing as group:   root
man pages owned by:    man
Installing into:       /tmp
Setuid capable:        no
Terminal control:      none
Linux wireless:        yes
pcap capture:          yes
pcap source:           libpcap-0.9.1-kis
WSP100 capture:        no
Viha capture:          no
Radiotap Headers:      local
using local dump code: yes
Imagemagick support:   no
Expat library:         no
GMP library:           no
PThread support:       yes
libz compression:      no

12. root@tty2#make

/home/user/whiterussian/openwrt/staging..../mipsel-linux-uclibc-g++ -Ilibpcap-0.9.1-kis Wall -g -O2 -Os -s -c <filename>
.
.
.
all done kismet_server is there and is 7.1MB in size

A little big for the WRT54G
So, I scp (secure copy) kismet_server over to my WRT and I try to run it.

root@tty2# scp /home/user/kismet-newcore root@192.168.0.255:/tmp/mmc/
Fire up PuTTY
root#/tmp/mmc/kismet_server -f /etc/kismet.conf
/tmp/mmc/kismet_server: can't load library 'libstdc++.so.6'

Now this tells me either the cross-compiler failed and didn't use uclibc

kismet-setup.sh

Code:

#!/bin/sh
clear
echo "Setting up Build Environment"

What are your thoughts on the matter? Do you see something missing?

CONCERNS:
in the ./configure line what is the purpose of
ac_cv_linux_vers=2.6.12

Is this telling the version of the kernel that is running on the router or the kernel version that's running on my laptop? I assume it's the version of kernel that's running on my laptop.

Did you try setting SEC to AUX?

Deleted all my directories and re-downloaded the buildroot. Gonna try it all over again. Should I put the export statements (minus the "export") in the configure and resulting MakeFile?

Gonna try Crosstool even though I have a feeling it won't work but then again it might. If I do ever get a properly cross-compiled kismet newcore I'll post a zip file so those of you with WRTs can try out the new drone and server.

Crosstool wouldn't wouldn't build, poopy. Back to buildroot.

I tried the same thing and for the same error. Any solution yet?

Don't remember what program this was but here are the results I was able to make work:

Kismet-newcore - successfully cc using buildroot
GPSD 2.10, 2.30, 2.31 - successfully cc using buildroot
GPSD 1.10 the stable version wouldn't compile errors with source not buildroot

So I got new-core to compile only to find Dragorn has finished the drivers for the WRT

If your firmware supports prismX/iwcommands for configuring it, use wrt54prism. Otherwise you're out of luck for now.

My V3 wrt54gs doesn't

I will post my buildroot config. Basically it's all the export statements, etc I paste into the console then I just do a normal ./configure, make and it uses the buildroot environment.

I haven't had a chance to test my GPSD mipsel binary but I'll post it on my website later so folks can try it out. Maybe I'll package it later but for now it'll be a tar.gz

Code:

echo  "Kismet Build Environment"

The Makefile will have some wrong pointers to

-I/user/include

capital i not number 1

which need to be replaced with

-I<buildroot path>/staging_dir_mipsel/usr/include
