[Spread-users] Cross Compile for ARM

[Arkadius Nowakowski]

Hello,

It worked for me by calling configure like this:

CC=arm-linux-gcc RANLIB=arm-linux-ranlib AR=arm-linux-ar LD=arm-linux-gcc \
./configure --target=arm-linux --host=arm-linux

Furthermore I have had to remove the check for snprintf inside the
configure script. The diff is attached to this mail.

Thankx for your help!

Best regards,
Arkadius
