Hi, All.

I need use kernel headers to build a IPU app.
I select KERNEL_HEADERS in ptxdist and I add
CFLAGS="-I$(KERNEL_HEADERS_INCLUDE_DIR)" in *.make.
Also I have added in the makefile -I$(KERNEL_HEADERS_INCLUDE_DIR)

But it still does not compile because it does not find the headers.
It looks like the variable KERNEL_HEADERS_INCLUDE_DIR is empty, this can be
seen in the output of the compilation.

Is there something wrong?

Thanks!
