Martin and all,

Thanks for your comments! 

I run cross-compiling by command "CC=arm-none-linux-gnueabi-gcc ./configure \
--build=i686-linux --host=arm-none-linux-gnueabi", but I met "-bash: gmp: command not \
found" issue. Cross-compiling failed.

I checked that gmp-4.1.4-6.2.1 had been installed on my fedora system. I suspect that \
it's caused by low version of gmp,  and I had tried to install a higher version of \
gmp-4.3.2, but it seems failed (After installing 4.3.2, rpm -qa | grep gmp still \
shows gmp-4.1.4-6.2.1).

Hi,

> Cross-compile is necessary, could anyone tell me detail steps?

strongSwan uses the autotools build system, which provides good support for \
cross-compiling. There is a lot of information out there how this works, have a look \
at [1] for a start.

Martin
