Experimental Physics and
Industrial Control System

I wish I had time to help, but I don't. The whole extensions build area could use cleaning up or replacing, but someone will have to volunteer to take that on, anyone interested?

I can try to cross compile base7 (I guess) et. al. for aarch64 on native 64bit Ubuntu.

Dong Ho, which cross compile tools do you use? Link to the toolchain I could run on x86_64 would help,  thanks.

Unfortunately there is no CONFIG_SITE.linux-aarch64.linux-aarch64 file in the extensions/configure/os directory; Dong Ho is the first person to use this host architecture (which is the 64-bit version of linux-arm and has only just been added to Base) and I suspect may have some difficulties.

My first instinct would be to copy the CONFIG_SITE.linux-x86.linux-x86 file to the name given above and edit it to match, but there are quite a lot of old and irrelevant paths in that file. I suspect the configuration for Ubuntu on linux-aarch64 would be closer to that of linux-x86_64, but the latter file just pulls in and overrides the settings from the 32-bit linux-x86 target. Maybe that would still work though.

CONFIG_SITE is meant to be locally edited for your site. Just make the changes you need for your arch.

If you get build errors post them here.

Hi, Mark
I followed the instruction you gave.
To build medm, CONFIGURE_SITE* file for linux-aarch64 is needed.
But I didn't find in the directory ../configure/os.
I guess most extensions for EPICS do not support aarch64.

First download this module:


https://github.com/epics-extensions/extensions


Then cd to that directory, and in that directory install this module:


https://github.com/epics-extensions/medm


The extensions/README explains how to build it.

Dear all,

I have succeeded to install EPICS base (Rver 7) with aysn & streamdevice supports.
And now I want to get install GUI tool, MEDM. Would you explain more detail how to build MEDM?
