Matlab/mexnc problem

[icecub_fr]

Hey fellow ubunters ,
I'm trying to install snctools to read and deal with netcdf file with Matlab on ubuntu 8.10 intrepid ibex. Following few different forums I got the netcdf, mexnc and snctools installed.
In matlab running >> help mexnc works.
Now when i try to use the snctools box i got this message:

>>nc_dump(url)
??? Invalid MEX-file '/home/flavien/mexnc/private/vanilla_mexnc.mexglx': /home/flavien/mexnc/private/vanilla_mexnc.mexglx: undefined symbol: mxCreateCharArray_700.

I'm annoyed since when I google it nothing comes up about this mxCreateCharArray...

anyone has an idea?

Thanks a lot,

Flav
