building driver with non-xilinx compiler fails
Description
when trying to build the dataplane driver for zynq with the arm-none-linux-gnueabi compiler we get the following error:
[embedded@localhost opencpi]$ make driver
make -C adapt/os/ocpios/linux/driver

this is not the standard opencpi compiler used but it is a valid compiler that is widely used and in theory this should work.
Environment
Activity
Was the entire opencpi build done with this compiler?
Was the kernel built with this compiler?
I imagine that the prebuilt zynq release was built using the Xilinx compiler.
Is this compiler used by other zynq kernels?
yes complete build was done with the other compiler. I was just unable to compile the driver using the provided headers. I was able to compile using the complete build tree that i was using before to build the kernel.

Let's remember to try this next week by generating the kernel-headers with this compiler.

We need to find the original reason why there were linking problems against the prebuilt OpenCPI libraries.
This is too stale.
