Ah, thanks. 

 

I've gotten as far as "make" and "make modules" successfully. How does one
"depmod" into the target file system I've set up for the ARM board instead
of into the development file system?

 

Thanks!

IIRC, the --with-linux-dir option cannot cope with relative paths nor ~
prefixed paths.  Specify the absolute path from / instead.

I'm trying to cross-compile the EtherCAT master for an ARM board. I
successfully built a Linux RT Prempt kernel for the device.  On my
development machine, the source tree where I built the kernel is at:
~/srcroot/linux/linux-3.2.46

 

I moved into the EtherLAB directory and issued:

 

./configure --host=arm-linux --enable-generic
--with-linux-dir=~/srcroot/linux/linux-3.2.46

 

The result is:

 

No configured Linux kernel sources in ~/srcroot/linux/linux-3.2.46/

 

But I just built a kernel there. Is there something I have to do to the
source tree to get it ready to build the ethercat master?

 

Thanks in advance,

Tome
