Help with the image package

[Filippo]

Hi I'm a beginner user of octave. I'm using QtOctave with Octave 3.2 version.
Trying to manipulate some image with the image package (version 1.0.10) i receive this error message:

error: Invalid call to imread. Correct usage is:

-- Function File: [IMG, MAP, ALPHA] = imread (FILENAME)

Additional help for built-in functions and operators is

available in the on-line version of the manual. Use the command

`doc <topic>' to search the manual index.

Help and information about Octave is also available on the WWW

at http://www.octave.org and via the address@hidden

mailing list.

So tinking that was fault of the image package I have tried to install the new version 1.0.13. In this case I receive thi error message:

make: mkoctfile: Command not found

make: *** [__spatial_filtering__.oct] Error 127

'make' returned the following error: make: Entering directory `/tmp/oct-wasDEj/

image-1.0.13/src'

mkoctfile -Wall __spatial_filtering__.cc

make: Leaving directory `/tmp/oct-wasDEj/image-1.0.13/src'

error: called from `pkg>configure_make' in file /usr/share/octave/3.2.3/m/pkg/p

kg.m near line 1253, column 2

>>>error: called from:

error: /usr/share/octave/3.2.3/m/pkg/pkg.m at line 287, column 7

Can you help me solving this issues?
