Re: How to configurate MCA for Octave

[Eric Norum <eric@norum.ca>]

You must set the EPICS_BASE and EPICS_EXTENSIONS environment variables and then run the buildForOctave.sh script.  I just tried this on a Linux machine here and all seems to work:

enorum 201> cd /usr/local/epics/R3.14.12/extensions/src/mca

enorum 202> export EPICS_EXTENSIONS=/usr/local/epics/R3.14.12/extensions

enorum 203> export EPICS_BASE=/usr/local/epics/R3.14.12/base

enorum 204> sh buildForOctave.sh

Did you try using the ‘buildForOctave’ script that is distributed with the MCA extension?

#!/bin/sh

#

# Provided by Eric Norum, APS, Dec. 2006

if [ -z "`env | grep EPICS_BASE`" -o -z "`env | grep EPICS_EXTENSIONS`" ]

then

    echo "Need EPICS_BASE and EPICS_EXTENSIONS environment variables" >&2

    exit 1

fi

MEX="mkoctfile --mex" FLAGS="-DmexAtExit=atexit" make MEXOUT=mex install

rm -f Channel.o MCAError.o TestHash.cpp mca.o

Caveat — it’s been a while since I’ve used this.

Hi Everyone,

I have just installed GNU Octave on Ubuntu 16.04 -x64. And also, I have just installed MCA extension. However, I could not configurate each of them . Therefore, I could not build MCA extension. I have 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

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

How can I figure this error out ? I am looking forward to your recommendations..

Thanks in advance,

Best Regards..

Hulusi
