Re: How to configurate MCA for Octave

[Eric Norum <eric@norum.ca>]

Your first message showed that make was trying to invoke ‘mex’.  This is not proper for octave.  The shell script I sent arranges for make to run the mkoctfile utility that is appropriate for octave.

Make sure too that your octave executables are on your shell search path:

enorum 205>  type octave mkoctfile

octave is /usr/bin/octave

mkoctfile is /usr/bin/mkoctfile

What commands are you running?   It sounds like you tried running ‘make’ again — this is incorrect.  You should run the script which will set things up as required by octave and then run make.

Please send the entire set of commands you are running and the resulting output.

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

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
