New Robot Configuration Compile Error [Solved]

12 Aug 2015 07:42 - 15 Aug 2015 21:36 #61302 by jstoquica
Good day,

Recently I did a kinematic file *.c and then compiled it successfully. First compiling with "run in place" and then compiling with sudo comp --install *.c

Then I did a simulation model *.py and everything sunshine.

But today, I want test the kinematics parameters with the simulation in vismach, and linuxcnc generated a error when I try to run.

Any idea for solve the error? Thanks.

irb: module license 'unspecified' taints kernel.


It has probably fallen foul of a peculiarity of the open source linux kernel.

They do not like proprietary module licensing and can refuse to load anything that does
not licence to an open source standard like GPL2

There used to be a lot of problems sometimes with nvidia drivers for linux. At the very least there was a complaint similar to the above and some would be refused and unloaded.

The remaining errors are because the symbol referenced is no found, possibly not exported properly? Can't guess without knowing where they come from.

(well they come from the posemath library, but don't know how they are used or the module was built.
If you are using modules that are not in modules.dep for that kernel, you have to make sure the referenced module is loaded first or you specifically export the function names)

is "irb" the name of your kinematics module?

Perhaps your config doesn't have "loadrt irb" at the top of the HAL, where "loadrt trivkins" normally goes?

Good Day,

irb: module license 'unspecified' taints kernel.


It was fixed with a simple line of code:
MODULE_LICENSE("GPL");

is "irb" the name of your kinematics module?

Perhaps your config doesn't have "loadrt irb" at the top of the HAL, where "loadrt trivkins" normally goes?


My HAL file has the changed name of the kinematics output file, after compiling the *.c file.

I attach the kinematics files, because I don't understand the warnings about posemath.h library.

Now the error when I run linuxcnc is:

When I see a string of errors like that I generally conclude that RTAI is all confused, and an incompatible set of interdependent modules are loaded.

Rebooting and trying again seems to be the only fix.

However: I am a bit surprised that you managed to compile a kins that contains posemath with comp / halcompile. Normally it can't work out the #includes.

Hi

If you are compiling a .c file, you should not really be using comp.

You probably need posemath in the build to link it in.

If you look at Makefile it specifically links it in for the *kins that require it

eg
obj-m += genhexkins.o
genhexkins-objs := emc/kinematics/genhexkins.o
genhexkins-objs += libnml/posemath/_posemath.o
genhexkins-objs += libnml/posemath/sincos.o $(MATHSTUB)

The easiest way is probably to build from a RIP and add your module to src/Makefile, copying all the entries for say genhexkins

As Andy said, comp is limited, and if not compiling an actual .comp file, you cannot even add user libs by the options method

Thanks for yours replies,

I am working with linuxcnc 2.5.4, and I downloaded the Source package for compile as "run in place", and the Makefile for modify it easy to find.

How can I compile my *.c file without comp/halcompile, with installed source, when I try to find that Makefile is so different that other one.

In the location /usr/src/linux-headers-2.6.32-122-rtai, there is other Makefile. How can I compile with my actual version? Thanks.

The Makefile in the kernel sources is a copy of the kernel Makefile, as one might expect, so no use to you.

I don't understand your reluctance, all you have to do is download the same version of the Linuxcnc sources, as you are currently using.
www.linuxcnc.org/dists/lucid/linuxcnc2.5...inuxcnc_2.5.4.tar.gz

Build a RIP and get your module built and working.
wiki.linuxcnc.org/cgi-bin/wiki.pl?Instal..._or_8_04_from_source
(just replace references to emc2 with linuxcnc and use the sources above)

You may well then be able to just transfer the module to your usr system.
The most you would have to do is rebuild as a user install and overwrite your existing
files from that install.

You are going to have to get to grips with RIP builds if you are going to do any sort of developing, because you need the sources and in this case need to link with intermediate object files.

What you can do with external components will be limited otherwise, some functions you will need are not exported publicly, as you have just found.

To add a new kinematics to the build, put it in src/emc/kinematics and duplicate the makefile lines here that are used for (for example) rotatekins.

Good day and thanks again,

I did:
cd src

In the source directory, build LinuxCNC:

./autogen.sh  (this builds the configure script)
./configure --enable-run-in-place
make clean
make
sudo make setuid

to run the software go back to the top level directory, and issue:

scripts/. rip-environment

And when I try to run my configuration, llinuxcnc generates the next advise:
Starting LinuxCNC...
puma560_sim_6.hal:4: module 'irb' not loaded

	rtai_shm

the path starts with one of:
	/lib/modules
	/usr/realtime-2.6.32-122-rtai

and the extension is one of:
	.ko

or the module is in the directory /home/asea/Documents/Files/Source/build/rtlib

OR

/home/asea/Documents/Files/Source/build/bin/linuxcnc_module_helper remove module

where module is one of the modules listed above.
