As dualbipod is not a distributed part of EMC2 it was not patched, presumably.
Using zero or checking for a negative returned value should work.

I use line like this one:
They are for sure derived from another kinetics module.
So it should look this I guess:
Gerd
if((res = hal_param_float_new("dualbipod2.D01", HAL_RW, &halXY->dist, comp_id)) != HAL_SUCCESS) goto error;They are for sure derived from another kinetics module.
So it should look this I guess:
if((res = hal_param_float_new("dualbipod2.D01", HAL_RW, &halXY->dist, comp_id)) != 0) goto error;Gerd

ok Andy, I think this is acceptable.
I did some more quick tests and I confirm:
If the path name from where you start comp contains blanks, comp fails. Not a big thing, but good to know. Maybe some expert can look at scripts and makefiles how to solve that. This is also in my old 8.04/2.3 system.
With above mentioned mods, comp finishes with warnings:
This is in 8.04/2.3 as well as in 10.04/2.4.
I ignored it up to now and it worked perfect in the old 8.04/2.3 system.
I could not test it in 10.04/2.4, but I think Wolfgang did and confirmed it works.

i remember this issue from older linux distributions, since those days i always avoid using blank spaces in files and folders names in linux (and also on windows..)

I have just got used to ignoring those. I see them sometimes when compiling the whole tree, not just with "comp"
The functions are defined in hal.h, so might disappear if that is put in the includes.

hal.h is included.

Hi there,
after heavy googleing and testing.
My proposal for getting out of this sandpit ist following:
1.) the emc2 modules do not have a Modules.symvers file. This file holds the dependencies of extern defined functions.
2.) the rtai modules do have this file.
So to get it work to check dependencies to avoid the above mentioned warnings, we must have a Modules.symvers file too for emc modules.
This is a little more work to do. And when we want to do it, then we should correct the whole things for modules, like not living in standard kernel trees.
Advice from kernel.org is to use
/lib/modules/kernel-vers/extra/rtai and ../emc
My proposal is to use
/lib/modules/kernel-vers/extra/emc
/lib/modules/kernel-vers/extra/rtai
The next point is, if we do so:
The kernel Makefile syntax for external modules was changed, this is not dramatically but we can write it shorter in our template.
New line for rtai modules would be:
$(MAKE) -C $(KERNELDIR) M=$(RTAIMOD) O=$(RTAIMOD)
with
RTAIMOD := /lib/modules/linux-2.6.32-122-rtai/modules/extra/rtai
KERNELDIR := /usr/src/linux-headers-2-6-32-rtai
and for emc modules:
$(MAKE) -C $(KERNELDIR) M=$(EMCMOD) O=$(EMCMOD)
with
EMCMOD := /lib/modules/linux-2.6.32-122-rtai/modules/extra/emc
KERNELDIR := /usr/src/linux-headers-2-6-32-rtai
If we do it in this way, the O=.... can be omitted.
In former times you have to use KERNEL_EXTMOD Variable for something like that.
Or, if do NOT want this, we should generate at least the Modules.symvers file for emc modules.
Kind Regards
Wolfgang

Hi Guys,
Now I'm a little bit confused, sorry. Is it now possible to compile bipod.c (from code.google.com/p/emc2hotwinch/ )or not? And if yes, can someone to this for me ;)
Or are there still problems to do comp with 10.04 and 2.4.4?
regards

I'm sure that I don't understand your question(s).
Comp is a program that creates HAL components and it works fine.
What are you attempting to do?
