The attached is log file captured in the process.

Thank-you. These were the only test failures:

epicsStackTraceTest.t ......... 

not ok  3 - dumping global symbols

not ok  4 - dumping local symbols

not ok  5 - dumping addresses

Failed 3/5 subtests 

Those will not affect the operation of the EPICS code at all, the epicsStackTrace API displays extra information in the event of some kinds of software crashes, but the functionality is completely optional, we will just need to adjust the code slightly for this architecture. I just filed a bug report so we can keep track that it needs doing.

I think we can declare the linux-aarch64 native build target working, these changes will appear in the next release of EPICS 7.

Thank-you for your help, and welcome to the EPICS collaboration!

Hi, Andrew

I send the output from command perl -V as you recommended.

I hope to fix the problem. 

Thanks,

Thank-you, that information was very helpful.

I have committed what I think should be the necessary changes to support your linux-aarch64 target to the default branch of our Git repository. Since you followed our how-to installation instructions you should be able to pull those modifications into your copy and build it as follows:

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

epics@epics-desktop:~/EPICS/epics-base$  git pull

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

If the build stops and displays one or more error messages, please copy the errors and the build command immediately before them into an email and send it to the EPICS tech-talk list so we can try to help fix it.

If the build finishes without any obvious error messages, please try running our built-in unit tests like this:

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

This will run several blocks of tests to check different parts of the software, displaying the results after each block. Please email us the results if you get any failures, and let us know if they all pass.

Good luck, and thank-you!

- Andrew
