Re: Help compiling synApps for linux-arm: opcua missing S7-1500-server.db

["Marco A. Barra Montevechi Filho via Tech-talk" <tech-talk at aps.anl.gov>]

Thanks, Akeroyd! Im going to take a look at it.

Can i consider that my EPICS base compilation is not right then?

In the link you showed me its written: "I’m also assuming you already have EPICS base downloaded and compiled"

The compiled EPICS here is compiled in the target architecture or the host? In other words: do i need to compile my EPICS base using this toolchain or can i use my current one, supposing ts compiled for amd architecture?

Regards,

Marco

Hi,

 

I hadn’t noticed you were compiling for linux-arm on amd64, I think you’ll need to set CROSS_COMPILER_TARGET_ARCHS rather than EPICS_HOST_ARCH maybe something along the lines of https://epics-controls.org/resources-and-support/documents/howto-documents/cross-compile-epics-ioc-old-x86-linux/

Hi, Freddie!

I tried adding it to configure/CONFIG_SITE inside opcua-v0-9-3 but it still doesnt work:

opcua-v0-9-3/exampleTop/DeviceDbApp/S7-1500Db# make

make -C O.linux-arm -f ../Makefile TOP=../../.. \

    T_A=linux-arm install

make[1]: Entering directory '/usr/local/epics-nfs/modules/R7.0.5/synApps/R6.1/support/synApps/support/opcua-v0-9-3/exampleTop/DeviceDbApp/S7-1500Db/O.linux-arm'

Inflating database from ../S7-1500-server.substitutions

I. -I.. -I../O.Common -I../../../db -o S7-1500-server.db -S../S7-1500-server.substitutions

make: *** [/usr/local/epics-nfs/base/R7.0.5//configure/RULES_ARCHS:58: install.linux-arm] Error 2

Should it be in cnofigure/CONFIG_SITE of synApps?

Thanks,

Marco

Hi Marco,

 

I think Tim is correct that the msi command has not been found. A version of MSI is shipped with EPICS 7, if it is not being picked up you may be able to just add

 

MSI = $(MSI3_15)

 

To e.g. configure/CONFIG_SITE

 

Regards,

 

Freddie

Hi Marco,

 

The tool that turns a .substitutions file into a .db file is MSI.  I think that's what's not being found.

https://epics.anl.gov/extensions/msi/index.php

EPICS Macro Substitution and Include Tool

MSI: Macro Substitution and Include Tool. MSI is a general purpose macro substitution/include tool. It accepts as input an ascii template file. Documentation

Hello all. Im compiling synApps with EPICS base R7.0.5 for linux-arm. The base has already been compiled for linux-arm here. (details about arm compilation at the end of e-mail).

I got the synApps support from https://github.com/EPICS-synApps/support. I then defined my EPICS_BASE to point to the right directory and EPICS_HOST_ARCH=linux-arm. I also added $EPICS_BASE/bin/linux-arm to PATH and $EPICS_BASE/lib/linux-arm to LD_LIBRARY_PATH. I edited EPICS_BASE inside assemble_synApps.sh to point to the right location.

In the compilation process i needed to install libnet-dev, libpcap0.8-dev and libusb-dev, all without trouble.

Now, inside synApps/support/opcua-v0-9-3/exampleTop/DeviceDbApp/S7-1500Db, when i run make i get the following error message:

/usr/local/epics-nfs/modules/R7.0.5/synApps/R6.1/support/synApps/support/opcua-v0-9-3/exampleTop/DeviceDbApp/S7-1500Db# make

make -C O.linux-arm -f ../Makefile TOP=../../.. \

    T_A=linux-arm install

make[1]: Entering directory '/usr/local/epics-nfs/modules/R7.0.5/synApps/R6.1/support/synApps/support/opcua-v0-9-3/exampleTop/DeviceDbApp/S7-1500Db/O.linux-arm'

Inflating database from ../S7-1500-server.substitutions

I. -I.. -I../O.Common -I../../../db -o S7-1500-server.db -S../S7-1500-server.substitutions

make: *** [/usr/local/epics-nfs/base/R7.0.5//configure/RULES_ARCHS:58: install.linux-arm] Error 2

2 things here make me curious: make[1]: I.: Command not found and mv: cannot stat 'S7-1500-server.db': No such file or directory

 

The "command not found" makes no sense to me at all. I tried following the Makefiles and includes to find where is the problematic command comming from but i couldnt find it. Im not fluent in make so i might be missing something silly.

The 'S7-1500-server.db': No such file or directory makes more sense to me: after cd into the opcua-v0-9-3 module and doing ´find -iname S7-1500-server.db´ i find nothing. I also find nothing with this name below EPICS base. Am i misunderstanding something or is this .db file actually missing?

Im compilng synApps just to get AreaDetector anyway, so i suppose i can just comment out opcua from my support/configure/RELEASE?

Thanks for any help,

Marco

 

Obs: details about arm compilation

 

The IOCs from this base and synApps are going to run in an arm machine, but the compilation is being made in a container hosted in an amd machine. Inside the container, uname -a returns:

Linux sol7-linux 4.9.0-11-amd64 #1 SMP Debian 4.9.189-3+deb9u2 (2019-11-11) x86_64 GNU/Linux

but i configured EPICS_HOST_ARCH=linux-arm

The base compiled with no problem.
I did this because we have a few arm machines in here and their EPICS_HOST_ARCH was defined this way. Am i forgetting anything important? Should just defining this env var make the compilation work for arm even if the host is amd?
