Re: How to configurate MCA for Octave

[Hulusi Öz <hulusi.oz1@gmail.com>]

I understand sir, I did like that. But when I add these path in Octave :

 (/opt/epics/extensions/lib/linux-x86_64) iand (/opt/epics/extensions/src/mca/matlab) ..

And in Octave when i type "help mcaopen" , it says the definition and usage of that command.

However, according to the your example,when I use Octave to read PV from the ioc like this 

         (pv=mcaopen('hulusiHost:ai1') , I've got this :

%%%%%%%

pv=mcaopen('hulusiHost:ai1')

error: mcaopen: /opt/epics/extensions/lib/linux-x86_64/mca.mex: failed to load: libCom.so.3.14: cannot open shared object file: No such file or directory

error: called from

%%%%%%%

In the search path of Octave these path are included.I can see them.

Thanks in advance..

Best Regards..

BuildForOctave.sh is all you need to do.   When it finishes you are ready to use MCA in octave.

Thanks for your recommendation. I made that. I'm new at either linux or EPICS platform. I'm still learning too much new things.

I just figured it out by adding "savepath" command after each of path command at the previous command. 

But still I'm getting error about mca.mex. I guess ,again, I couldn't build MCA extension in terms of mex file. I run the script (buildForOctave.sh) and after that, I run make. I've got this error :

%-----------%

mex -v -I/opt/epics/base/include -I/opt/epics/base/include/os/Linux -DEPICS_DLL_NO -L/opt/epics/base/lib/linux-x86_64 -ldbStaticHost -lCom -lca mca.cpp MCAError.cpp Channel.cpp -o O.linux-x86_64/mca.mexglx

make: mex: Command not found

Makefile:66: recipe for target 'O.linux-x86_64/mca.mexglx' failed

make: *** [O.linux-x86_64/mca.mexglx] Error 127

Thanks in advance..Best Regards..

Thank you so much sir.. It works fine.

The things that I've done so far since yesterday are :

1) I managed to build MCA extension for Octave properly.

2) Now,I can run the examples.

3) But, I think ,I miss something about editing path for octave for mcaget,mcaput.. commands,because Octave doesn't see those commands. But I had done it by doing that in Octave : 

path(path(), [getenv("opt") "/opt/epics/extensions/lib/" getenv("linux-x86_64")]); path(path(), [getenv("opt") "/opt/extensions/src/mca/matlab"]);

Once you have your PATH set properly you should need to type only

makeBaseApp.pl …….

since that script is in the EPICS base bin.

1) I make an IOC example with 

                 "../../../makeBaseApp -t example example"

                 "../../../makeBaseApp -i -t example example"

I've got the same result as the same with Eric Norum's.
