Hi Rémi,

recently we have successfully tested CA Lab (LabVIEW-EPICS interface)
for real time systems.
Our test device was a PXIe with RT Linux os.
We were able to install EPICS Base V7 on it without any problems.
For Perl installation we did the following:

wget http://www.cpan.org/src/5.0/perl-5.20.1.tar.gz
tar -xzf perl-5.20.1.tar.gz
cd perl-5.20.1
./Configure -des -Dprefix=$HOME/localperl
make
make test
make install

We have built the EPICS base as follows:

opkg install git*
mkdir /usr/local/epics
cd /usr/local/epics
git clone --recursive https://github.com/epics-base/epics-base.git
cd /usr/local/epics/epics-base/
export PATH=$HOME/localperl/bin:$PATH
make
cd /etc/ld.so.conf.d
create epics.conf => /usr/local/epics/epics-base/lib/linux-x86_64/
ldconfig

Regards,
Carsten Winkler

Subject: build EPICS IOC on CRIO

Hi everyone,

I tried to build an EPICS ioc on a CRIO-9064 which is under RT Linux os.

Since CRIO's os is Linux my first thought was to build the ioc directely
on the CRIO avoiding one layer of hardware.

I am connecting from a windows PC to CRIO via ssh (Putty).

After Installing (with opkg) git (to clone EPICS base repository), make,
perl and gcc, I encountered error while executing "make" command to
build the base. I tried it with base V7 and V3.16 and I had the same error:
Can't locate POSIX.pm in @INC (you may need to install the POSIX module)
(@INC contains: /etc/perl /usr/lib/perl/site_perl/5.24.1/
/usr/lib/perl/site_perl/5.24.1 /usr/lib/perl/vendor_perl/5.24.1/
/usr/lib/perl/vendor_perl/5.24.1 /usr/lib/perl/5.24.1/
/usr/lib/perl/5.24.1 /usr/local/lib/site_perl /usr/lib/perl/5.24.1 .) at
./src/tools/EpicsHostArch.pl line 28.

Can't locate FindBin.pm in @INC (you may need to install the FindBin
module) (@INC contains: /etc/perl /usr/lib/perl/site_perl/5.24.1/
/usr/lib/perl/site_perl/5.24.1 /usr/lib/perl/vendor_perl/5.24.1/

/usr/lib/perl/5.24.1 /usr/local/lib/site_perl /usr/lib/perl/5.24.1 .) at
./src/tools/convertRelease.pl line 16.
BEGIN failed--compilation aborted at ./src/tools/convertRelease.pl line 16.
configure/CONFIG:58: configure/os/CONFIG..Common: No such file or directory
make: *** No rule to make target 'configure/os/CONFIG..Common'. Stop.

It seems that no module from perl was correctly installed. Unfortunately
I found nothing on internet to solve it. I'm stuck here at the moment

At the same time I am asking myself if I am on the right way to
establish the communication between EPICS and variables from a CRIO.
Searching a solution I found the conversation about CRIO and EPICS from
2018.
https://epics.anl.gov/tech-talk/2018/msg01205.php

One of the solutions mentionned is to build a base+ioc separately from
CRIO and write shared variables data in the records via the EPICS client
provided with NI Datalogging and Supervisory Control (DSC) module.

Are the information in this discussion up to date?

Thank you in advace for help.

Yours sincerely,
