Hello,
The test code below for writing an image to a file crashes octave. Would
anyone be able to help? I am using octave-3.2.4-r1 and graphicsmagick-1.3.12
Thanks,

Hi,
I tested your code (and variations of it) and I get the same result
as you. Googling seems to indicate that lots of other people are having
similar problems with imwrite/imread function. The functions are not
part of the octave package but is an add-on. However, from

Since octave compiles/emerges successfully, there are no log files left.
Can I tell emerge to not remove the build directory ?
Octave won't run since a lib is missing.
I can re-emerge it without problems, but the problem still
persist. The lib is there but it has a different version.
Anyone know what this is about ?
$ ldd /usr/bin/octave-cli-4.2.2 | grep not
liblapack.so.0 => not found
$ ls -l /usr/li
/CBLAS (lib) candidates:
(none found)
Available BLAS/CBLAS (lib64) candidates:
[1] reference *
still same problem.
recompiling octave, same problem.
recompiling octave with static-libs, same problem.

Yes, that short term solution works.

You motivated me to look this up on my system, and I don't think that's right:
- octave depends on virtual/lapack, and
- virtual/lapack does *not* depend on lapack-reference:

first.
Thank you for your help.
I tried this, what you pointed

i guess a general scientific tool like octave (a free alternative to
matlab, the de facto standard among scientists) would do all you may
possibly want to do, although learning the language might require some
time. i don't know of any ready-to-go tool for dsp where you just put

a simple app to do what I need to do. It's not
generally difficult stuff but it requires (or I prefer) a lot of small
charts. I'm vaguely familiar with C Pascal, but haven't programmed
in years. I don't know C++ at all. I was trained as an EE.
Have you looked at using Octave? It's a Matlab clone

recommended reading, I read other ebuilds; reasonably complex ones like

ebuilds.
Lastly, if you throw this in a publicly-accessible git repo I'll try and

The funny thing is that the day before, on another computer, portage resolved
