Re: Compiling IOC with sequencer from scratch. seq command not found.

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

Solved.

After looking a little more in_depth into the compiled example i found:

SoftCedApp/src/O.linux-x86_64/sncProgram.c:    seqRegisterSequencerProgram (&sncExample);

Compiling my incomplete IOC application without the dbd file i found the c code that comes from the stt file:

./SoftKinApp/src/O.linux-x86_64/Kinematics.c

and it has:#include "epicsExport.h"

static void imbuia_kinematicsRegistrar (void) {

    seqRegisterSequencerCommands();

    seqRegisterSequencerProgram (&imbuia_kinematics);

}

epicsExportRegistrar(imbuia_kinematicsRegistrar);

So it became clear to me that the argument is the name of the program declared in the stt file, not the name of the file itself.

Sorry for the confusion, thanks for your patience and time ��

Marco

No, i didnt. Im unfortunately not very familiar with this command.

Im looking at this documentation right now to try to understand exactly what it expects as argument: https://epics.anl.gov/base/R3-15/5-docs/AppDevGuide/IOCShell.html. It seems to me it creates the proper ioc shell function, which is exactly what i want. But its not clear to me where does the compilation gets the source from and what should my argument be.

I added a file called Kinematics.dbd to my src folder, added 

SoftKin_DBD += Kinematics.dbd

To my makefile, but whatever i try to put inside the .dbd file generates compilation error. I tried:

registrar(sncExampleRegistrar)
registrar(sncKinematics)
registrar(sncKinematicsRegistrar)
registrar(sncSoftKin)
registrar(sncSoftKinRegistrar)
etc...

Compilation error:

Did you remember to add the registrar command for your sequencer program to your application dbd file?

Hello all, good evening.

Im sorry if the doubt is trivial, but i cant find what the problem is.
Since makeBaseApp.pl -t example ioc generates several things that i dont need in my application, im trying to compile a sequencer stateMachine from scratch, with makeBaseApp -t ioc. Following the documentation (https://www-csr.bessy.de/control/SoftDist/sequencer/Installation.html#configure-and-build) i did:

> makeBaseApp.pl -t ioc SoftKin
> makeBaseApp.pl -i -t ioc SoftKin

Added the path to my sequencer installation as SNCSEQ in configure/RELEASE file. Added an example state machine file called Kinematics.stt in SoftKinApp/src/ folder and in the Makefile:

SoftKin_SRCS += Kinematics.stt
SoftKin_LIBS += seq pv

I compiled it and it went OK. Kinematics.stt was clearly transformed into a cpp code and then compiled.

However, when starting the IOC, at the end of my cmd file i get:

seq Kinematics,"BLP=SOL:,HP=S:,MP=m1"
st.cmd line 22: Command seq not found.

Am i forgetting something in the Makefiles? I tried using the examples of makeBaseApp.pl to understand what is missing but i think im getting lost in application name conversions. I append cmd file, configure/RELEASE and SoftKin/src/Makefil at the end of this e-mail.

Thanks for any suggestions,

Marco
