Insufficient memory for signal/pin

I have got a lot:
2198 pins
887 signals

The error message is: HAL: ERROR: insufficient memory for signal 'name-of-signal'. So I guess the number of signal is too important. When I comment some of the signals required the message goes off and linuxCNC works no matter the latest component which was loaded. So I think it is really the amount of signal which is part of the issue.

Any way to increase the memory for the HAL program, if yes, how can I do that? I have been trying to modify the /etc/security/limits.d/limits.conf without any results.

Thanks

Should I modify the HAL KEY or the HAL_SIZE? And which value should I put to modify one of this, especially if it is the HAL key which need to be modified.

At the moment I am still in the development phase, so I am still creating lots of pins and would like to be able to extend the memory. Surely will do a bit of cleaning once I get a more finalized version of the hal configuration I will eventually used. But so far, all components are used and I can hardly reduce the amount of pins.

Hi,

thanks for your advice. I managed to achieve some additional function for my project, by removing some other hal components or their pins function that were not used. Nevertheless the project has become bigger and I am at the point where I have removed all non used component pins. So here we go, I need all the hal elements loaded on my project but if I add one additional pin to any component I got the Hal insufficient memory error message.

I guess I have now to increase the memory for the hal. Can you indicate me how to do that more precisely from the file you have indicated earlier, especially to be able to recompile only the required file related to hal without the compiling everything for linuxcnc.

Thank you,

Nicolas

looking at git commit b9ac31f:
in src/hal/hal_priv.h
basically this
then recompile

Hi,
so I guess my idea would be to compile only the .hal component if I want to keep the rest of LinuxCNC as it is. I would just then need to run a make on the hal component folder, is that it?
