Thanks for the reply Yaroslav,
That worked! I ran (sudo) apt-get install liboctave-dev any reason why the
install didn't take care of that?
What happened is that on older systems using octave2 libraries versioned
suffix got stripped while linking against that library:
% for d in *amd64; do echo -n "$d "; ldd
$d/usr/share/octave/site/m/psychtoolbox-3/PsychBasic/PsychPortAudio.mex | grep
liboctinterp; done
octave-psychtoolbox-3_3.0.12.20160126.dfsg1-1_amd64 liboctinterp.so.3 =>
not found
octave-psychtoolbox-3_3.0.12.20160126.dfsg1-1~nd14.04+1_amd64 liboctinterp.so
=> not found
octave-psychtoolbox-3_3.0.12.20160126.dfsg1-1~nd15.04+1_amd64 liboctinterp.so
=> not found
octave-psychtoolbox-3_3.0.12.20160126.dfsg1-1~nd15.10+1_amd64 liboctinterp.so.3
=> not found
octave-psychtoolbox-3_3.0.12.20160126.dfsg1-1~nd+1_amd64 liboctinterp.so.3
=> not found
octave-psychtoolbox-3_3.0.12.20160126.dfsg1-1~nd80+1_amd64 liboctinterp.so
=> not found
octave-psychtoolbox-3_3.0.12.20160126.dfsg1-1~nd90+1_amd64 liboctinterp.so.3
=> not found
so they got linked against plain .so which is a symlink provided only by -dev
package.
We will fix it for the next upload, thanks for the report!
Meanwhile indeed just install liboctave-dev as a workaround
That's probably because following your tip, i modified the
striplibsfrommexfile.m file to rename the liboctinterp.so.[23]
dependency from .so.1 or .so.2 to only .so, so i don't need to build and
ship separate mex files for Octave-3 vs. Octave-4 although the required
libraries are api/abi compatible.
Maybe your version of striplibsfrommexfile.m needs to carry a patch to
avoid that rename?
As it happens, I also had to run sudo apt-get upgrade alsa-utils to get
PsychPortAudio to work...
what was the error? I wonder if -utils is really what needed or some
missing library somehow
It needs libasound.so the ALSA runtime library. I don't think it needs
-utils, although those come in handy anyway for tweaking of ALSA for
some use cases.
cheers,
