Hello Sebastian,
I'm trying to make a component to add an offset to the X axis of a grinder
to compensate the radius of the wheel and then grind lobes with the shape
previously generated and loaded into that component.
For that I need to do some trigonometric calculations inside the component.
The problem is that, whatever component I try to build, no matter if it's
mine, or if I copy and paste one of the examples on the docs I always get
the same error message. I'm using LinuxCNC 2.5.4 on ubuntu 10.04, I
installed the latest Live CD available on the website.
This is the source code of the example component I created and I can't load:
*component sincos;pin out float sin_;pin out float cos_;pin in float
theta;function _; license "GPL"; // indicates GPL v2 or later;;#include
<rtapi_math.h>FUNCTION(_) { sin_ = sin(theta); cos_ = cos(theta); }*
Then this is the all the way through the console from installing with comp
to the error when loading the component, also you can see that although I
get the message that the component is not loaded, I can still see it loaded
in hal.
*leonardo@leonardo-desktop:~$ sudo comp --install senito.comp [sudo]
password for leonardo: make
KBUILD_EXTRA_SYMBOLS=/usr/realtime-2.6.32-122-rtai/modules/linuxcnc/Module.symvers

show pinComponent Pins:Owner Type Dir Value Name 4 float
OUT 0 sincos.0.cos 4 float OUT 0
sincos.0.sin 4 float IN 0 sincos.0.theta*
This happens with every component I try to load compiled with comp. When I
install mine, I also get the following message, I colored with red the line
that worries me about the frame size:
*leonardo@leonardo-desktop:~/Documentos$ sudo comp --install
compensacion-leva.comp [sudo] password for leonardo: make

Anyway, apart from that warning when I load it the same happens as with all
the other codes.
Any ideas?
Thanks for the help!
Leonardo.
