Re: GUI - start?

[jkr]

Alexander,

Followed your instructions below.  At one point my iMac was hung for over a 
half hour (even clock on screen not updating, no disk noises) and I forced it 
to power down.  This was apparently during fink install octave-qtmacs 
octave382-dev.  After rebooting, I did findk list -it octave and got:

 i      fink-octave-scripts     0.3.3-1 Convenience scripts for Octave add-ons
 p      liboctave382            [virtual package]
 p      liboctave382-accelerate         [virtual package]
 p      liboctave382-accelerate-dev             [virtual package]
 p      liboctave382-aqua               [virtual package]
 p      liboctave382-aqua-dev           [virtual package]
 p      liboctave382-dev                [virtual package]
 p      liboctave382-gcc49              [virtual package]
 p      liboctave382-gcc49-dev          [virtual package]
 i      octave382       3.8.2-4 MATLAB-like language for computations
 i      octave382-dev   3.8.2-4 MATLAB-like language for computations
 p      octave382-interpreter           [virtual package]
 p      octave382-interpreter-accelerate                [virtual package]
 p      octave382-interpreter-aqua              [virtual package]

Then I did fink install octave-qtmac octave382-dev, counting on fink to figure 
out whether it had any work to do (as the list looked incomplete - no qtmac).  
This appeared to work, apart from complaints about not being able to stat 
unstable/crypto/...  It said it found that it needed to install both packages, 
but took hardly any time.  Next it said:

Could not resolve inconsistent dependencies!

Fink isn't sure how to install the above packages safely. You may be able to
fix things by running:

  fink scanpackages
  sudo apt-get update
  sudo apt-get install octave-qtmac=3.8.2-4 octave382-qtmac=3.8.2-4

So, I ran all of the recommended commands.  During sudo apt-get install 
octave-qtmac-3.8.2-4 octave382-qtmac=3.8.2-4 it said:

The following packages will be REMOVED:
  octave382 octave382-dev 
The following NEW packages will be installed:
  octave-qtmac octave382-qtmac 
0 packages upgraded, 2 newly installed, 2 to remove and 0  not upgraded.
Need to get 0B/26.7MB of archives. After unpacking 791kB will be freed.

Then it appeared to proceed gracefully except for warnings like:

Removing octave382-dev ...
Removing octave382 ...
dpkg - warning: while removing octave382, directory `/sw/var/octave/3.8.2' not 
empty so not removed.
dpkg - warning: while removing octave382, directory `/sw/var/octave' not empty 
so not removed.
dpkg - warning: while removing octave382, directory `/sw/share/octave' not 
empty so not removed.
dpkg - warning: while removing octave382, directory `/sw/lib/octave' not empty 
so not removed.

Finally it said Setting up octave-qtmac (3.8.2-4) ..., which it appeared to do 
successfully.

Next I ran octave --force-gui

It brought up a beautiful GUI.  Command line recall worked.  But on a first 
simple plot I got a dialog "octave-gui quite unexpectedly" and on the command 
console "octave exited with signal 11".

I tried starting again at remove --recursive octave382.  fink said No packages 
to remove. I tried 'fink remove octave382' - same answer.  'find remove 
octave382-interpreter', same answer.  

I tried using octave from its command line.  I generated a simple plot, but on 
the command console, it posted pages of:

Dec  1 17:46:56 Jamess-iMac.local octave-cli-3.8.2[1459] <Error>: 
CGContextFillRects: invalid context 0x0. This is a serious error. This 
application, or a library it uses, is using an invalid context  and is thereby 
contributing to an overall degradation of system stability and reliability. 
This notice is a courtesy: please fix this problem. It will become a fatal 
error in an upcoming update. 

(repeated many times).

I feel totally snake-bit.  It seems like I need to start over with a fresh 
installation, but it seems like I cannot.  Recommendation?

Thanks,

Jim
