Although your build process seemed to work okay, and no errors
were reported, it has changed my system to where qjackctl crashes
every time I try to run it. I have listings of all the retrieval
& build steps, if that would be helpful in determining the
problem.
qjackctl is completely independent of fluidsynth. Its quite unlikely
that instaling fluidsynth causes it to crash. Anyway, what one does
in that case is to fire up the debugger:
gdb qjackctl
run
and when you get the crash
bt
to get the backtrace of the crash.

Qsynth, on that system, is configured to use jack, and it reports
that jack is not there, and that it can't continue without it. At
that point, I can click the "Setup" button on Qsynth, and change
the audio to PulseAudio, but after hitting the OK button, Qsynth
exits, and when I restart it, it again reports that it cannot run
because jack is not running.
I did not find any ".qsynth" or ".fluidsynth" folder to change the
configuration manually.
I tried re-installing qjackctl, but that did not make any
difference. Qjackctl still crashes. In the past, I have not been
able to figure out how to run fluidsynth from the command line
successfully. If I could, I could possibly run fluidsynth that
way.
I know to all of you, running fluidsynth from the command line is
easy and natural, but using a GUI application (Qsynth) is
difficult. For me, it is the exact opposite.
So it seems I have hit a dead-end on this, unless someone has any
ideas.
The partition I built fluidsynth on (on that machine) is now
unusable as a music workstation, but I plan to install
Ubuntu-Studio on it anyway, so it isn't a terrible loss. Still,
it would be nice if I could somehow fix it (for the time being).

Thanks!

The doxygen error can be ignored.

Try verifying by running these two commands:
1) "which fluidsynth", should return /usr/local/bin/fluidsynth
2) "ldd /usr/local/bin/fluidsynth | grep fluid", should return
"libfluidsynth.so.1 => /usr/local/lib/libfluidsynth.so.1" (followed by a
hex number).
If the second one fails, i e, points to somewhere in "/usr/lib" instead
of the newly installed file in "/usr/local/lib", try running "sudo
ldconfig", then try again.
Let me know how this goes.
