Thanks for the reply!
So I am able to compile the kernel folder.
Then, in userland, I modified the main Makefile by adding (at the beginning):
>export MY_CROSS_COMPILE=arm-linux-gnueabi-
>export MY_ARCH=arm
>export MY_HOST=arm
>export MY_CC=arm-linux-gnueabi-gcc
and then modifying each entry in this way:
>libpfring:
> cd lib; ./configure --host=${MY_HOST} CC=${MY_CC}
> CROSS_COMPILE=${MY_CROSS_COMPILE} ARCH=${MY_ARCH}; make CC=${MY_CC}
> CROSS_COMPILE=${MY_CROSS_COMPILE} ARCH=${MY_ARCH}
>
> [etc...]
when running the main makefile, I get the errors while compiling the folder
libs:

Subject: [Ntop-misc] A question about cross-compiling PF_RING for ARM
Message-ID:
<[email protected]>
Content-Type: text/plain; charset="us-ascii"
Hello everyone,
I have a question related to compiling PF_RING. I want to cross compile it for
ARM, and
I encountered some issues. I was able to cross-compile the kernel module,
however I'm having some bigger
trouble while doing the same for "userland" codes.
The problem arises when trying to cross-compile the folder userland/lib.
Regardless of what combination
of cross-compilation options I use, at some point I get some unmet dependencies
or unrecognized files.
For example, when compiling with:
> make CC=arm-linux-gnueabi-gcc CROSS_COMPILE=arm-linux-gnueabi- ARCH=arm
I get:
> pfring_dna_bouncer.o: file not recognized: File format not recognized
I found out that the folder userland/lib/libs contains some dependencies that
probably work only for x86.
Thus, is it actually possible to cross-compile your software for ARM? Or the
other hand, the Makefile contains
${CROSS_COMPILE} variables, so it would suggest there is a way for achieving
this.
Thank you for any help/advice!

Besta
Can you please provide a comprehensive error report with exact errors? We
compile on ARM from time to time as you can see
