Hi all,
I'm having trouble getting an old driver originally built for Xenomai 2.4
to build under Xenomai 3.0.5. The code won't build under Ubuntu 16.04
patched with Xenomai 3.0.5 and kernel 4.9.24 and the IPipe patch for 4.9.24.
The problem seems to revolve around include pathing, and the simplest case
I can put together is as follows:
------------------
Makefile
------------------
XENOCONFIG:=/usr/xenomai/bin/xeno-config
KDIR ?= /lib/modules/`uname -r`/build
INCLUDEDIR :=/usr/include
PWD := $(shell pwd)
$(eval ccflags-y = -v $(shell $(XENOCONFIG) --native --rtdm --compat
--cflags))
ifneq ($(KERNELRELEASE),)
obj-m := rfidrv2.o
else
rfidrv : rfidrv2.c
$(MAKE) -C $(KDIR) M=$(PWD) SUBDIRS=$(PWD) modules
endif
------------------
rfidrv2.c
------------------
#include <native/heap.h>
// Yes, just the one include line -- I removed all the rest of the code
===============================================
Output:
make -C /lib/modules/`uname -r`/build M=/home/jlangston/mi/rfidrv/rfidrv
SUBDIRS=/home/jlangston/mi/rfidrv/rfidrv modules
make[1]: Entering directory '/usr/src/linux-4.9.24'
CC [M] /home/jlangston/mi/rfidrv/rfidrv/rfidrv2.o

Does anyone have a driver that they could post up that uses the heap
functions, a sample 'Makefile' with different flags/include options, or any
suggestions on how to resolve the include file mess here?
Thanks,
Jim
