Re: Short report Cygwin Octave-2.9.13

[Tatsuro MATSUOKA]

Dear David

It is my great honor for your inviting me octave-forge.

As you pointed out, '--disable-silj-exception' flag on GCC
is not comtatible standard cygwin install.
So my current distribution, the GCC configured with this
flag was basically prepared only for the octave.
In the octave preparation, 

export CC='/usr/local/gcc-3.4.4d/bin/gcc'
export CXX='/usr/local/gcc-3.4.4d/bin/g++'
   :
   :
./configure .....

The mkoctfile uses the absolute path to the GCC so that
the confliction with the standard GCC on the Cygwin is
avoided.

I found the following post from search engine, so I tried
gcc-3.4.4-3.
http://sourceware.org/ml/cygwin/2004-11/msg00007.html

As for the standalone package, do you mean the package
like the octave-forge 2.1.73 ?

In my opinion, it is questionable to distribute the
standalone packge like the the octave-forge 2.1.73.
The MSVC octave-2.9.13 is now officially distributed, I
think that most windows users use it.

The purpose of my binary distrubuion of the cygwin octave
is for daily users of cygwin like me.
(I currently uses the octave and the cygwin gnuplot. )

Consulting the history of octave-forge windows
distribution, I found the following 

octave-2.1.42-cygwin (2003-03-03 21:00) 
  octave-2.1.42-gnuplot-octaveforge-...
     :
     :

I think that this type of distribution will be reasonable.

However, to avoid confusion, the binary should not be
installed in /usr/bin or /usr/local/bin.
I think that it will be installed like
/usr/bin/octave-2.9.13.

In the directry, all packages, octave, gnuplot4.3, GCC,
the related library, octave-forge functions.

My idea is:

1. Basic Packege : octave and gnuplot4.3
2. Octave-forge binary package and its octave script
installer.
3. Developer kit : GCC and the related libraries and
included files.

Thank you again and it will be grateful for me if you will
give me the reply.

I am also waiting for other contributors opinion.

Sincerely,
T. Matsuoka
