extensions CONFIG_SITE file for linux-aarch64 of Raspberry Pi 64-bit OS

[Akira Chen via Tech-talk <tech-talk at aps.anl.gov>]

Hi there,

      Recently, I tried to install epics base and its relatively simple modules and extensions. During the installation, I found there is no CONFIG_SITE of extensions for linux-aarch64. I learned from community of EPICS's tech-talk, and found Dr. Jeong Han Lee had tried to make one for linux-arm, so I tried to use Dr. Jeong Han Lee's experience to make one for linux-aarch64.

  Here, I use the following

packages:

  * baseR7.0.6.1
  * extensions_20120904
  * StripTool2_5_17_0
  * alh1_2_35
  * medm3_1_17
  * probe1_1_8_0
  * cau_phoevus_20130115

tested Hardwares:

  * Raspberry Pi 4
  * Rock Pi 4 C+

tested OSs:

  * Raspberry Pi OS with Desktop 64-bit Release date:Apr 04 2022 (Raspberry Pi 4)
  * Ubuntu Server 20.04.4 with post Desktop installation (Rock Pi 4C+)


before make aarch64-ubuntu extensions we have to install the following packages

sudo apt-get install libxt-dev
sudo apt-get install libmotif-dev
sudo apt-get install x11proto-print-dev
sudo apt-get install libxmu-headers
@sudo apt-get install libxp-dev
sudo apt-get install libxmu-dev libxmu6


@ aarch64 has no libxp support for apt

Since there is no libxp for easy installation, we can obtain libxp in this website

https://archlinuxarm.org/packages/aarch64/libxp

get this file.

http://mirror.archlinuxarm.org/aarch64/extra/libxp-1.0.3-5-aarch64.pkg.tar.xz

copy and extract this file in root directory /


make a CONFIG_SITE.linux-aarch64.linux-aarch64 file in
${EPICS_ROOT}/extensions/configure/os       for aarch64

After this, I could compile the extensions packages ex: medm, Striptool, and alh.

But I am not a developer of EPICS, so I don't know whether there is any restriction to add this file into the extensions folder. Maybe it still needs some modification. And I hope this will be helpful for other aarch64 users.
