I'm trying to install epics base on NVIDIA Jetson nano (Ubuntu 18.04).

I followed the instruction documented in https://docs.epics-controls.org/projects/how-tos/en/latest/getting-started/installation.html.

I typed make and got below messages.

epics@epics-desktop:~/EPICS/epics-base$ make

./src/tools/EpicsHostArch.pl: Architecture 'aarch64-linux-gnu-thread-multi' not recognized

configure/CONFIG:58: configure/os/CONFIG..Common: No such file or directory

make: *** No rule to make target 'configure/os/CONFIG..Common'.  Stop.

I looked inside EpicsHostArch.pl and found there was no rule for 'aarch64-linux-gnu-thread-multi'.

Can I add a rule for that? If possible, would you tell me how to do?

EPICS target names are not the same as Unix ones; the EPICS target name for your system should be linux-aarch64 but we only added the configuration files for that particular architecture to Base in the very latest release (EPICS 7.0.4.1) and only for cross-building that target. You may be able to use the linux-arm target instead though, try doing this:

If that works you will need to set the EPICS_HOST_ARCH variable like that whenever you build EPICS code, so it might be worth putting that statement into your ~/.bashrc or ~/.profile file.

I would like to add full support for this architecture to EPICS though. if you want to help please send me the output from the command  perl -V  on that system.

Thanks,
