Hi Johannnes,
I changed the toolchain to the uclibc one, but now I cannot crosscompile the ibrdtn tools as can be seen below, I need to add something more ?
Regards and thanks again

Hello Johannes,
Thanks for replying so fast ;D
I will change the toolchain to uclibc and try again, I will let you know the outcome.

Hallo Francisco,
you have build your packages using OpenWrt based on the eglibc library. But default OpenWrt images (available from the website) are based on uclibc instead. That means your binaries are linked against the wrong c library and you need to switch to a OpenWrt system which is also based on eglibc or switch to a toolchain based on uclibc. I recommend the latter case.
Kind regards, Johannes

I have checked out that the library is there and I have found it

/attitude_adjustment_rPi/staging_dir/toolchain-arm_v6_gcc-4.6-linaro_eglibc-2.15_eabi/lib/libm.so.6
and on my openwrt the library is present as well root@OpenWrt:/lib# ls -la | grep libm -rwxr-xr-x 1 root root 615996 Mar 22 2014 libm-2.15.so http://libm-2.15.so lrwxrwxrwx 1 root root 12 Mar 22 2014 libm.so.6 -> libm-2.15.so http://libm-2.15.so
So then is it a matter of crosscompilation?
Thanks in advance,
Regards
