Dear Gerardo,

it seems that with SuSE Linux there is always the same type of problems w=
hen=20
trying to install Scigraphica. The libtermcap.so is usually part of the S=
uSE=20
system and is located in the directory /usr/lib. With former versions of=20
Scigraphica, the problem was that this library had to be addressed using =
a=20
different name - say libtermcap.so.2.0.8 or the like. So it helped to def=
ine=20
the respective link to make things work.

By the way, a similar thing happened with the libreadline.so, so if=20
Scigraphica should freeze if you try to type numbers into a worksheet, th=
is=20
might be the reason.

***

The message:
'couldn't import module "Numeric"'

points to another problem which exists with Scigraphica under SuSE 7.3. I=
t is=20
the fact that for some obscure reason the system path for the Python syst=
em=20
is not set in the correct way. To check this, please type the command:

sys.path

into the python window. If you get something like:

['/usr/lib/python2.1/lib/python2.1/',=20
'/usr/lib/python2.1/lib/python2.1/plat-lin
ux2', '/opt/gnome/share/scigraphica/python',=20
'/usr/lib/python2.1/lib/python2.1/l
ib-tk', '/usr/lib/python2.1/lib/python2.1/lib-dynload']

you got the same problem as I got. A path '/usr/lib/python2.1/lib/python2=
.1/'=20
does not make sense, it should be '/usr/lib/python2.1/'. In the case of=20
Scigraphica 0.7.1, I found a workaround using the following "script":

sys.path=3D['/usr/lib/python2.1/', '/usr/lib/python2.1/plat-linux2',=20
'/usr/lib/python2.1/lib-tk', '/usr/lib/python2.1/site-packages',=20
'/usr/lib/python2.1/site-packages/Numeric', '/usr/lib/python2.1/lib-dynlo=
ad',=20
'/usr/share/scigraphica/python']
import pickle
import gtk
import Numeric

The first four lines contain the redefinition of the sys.path variable -=20
please write all that stuff into one line, because it is word-wrapped by =
my=20
eMailer. The three 'import' commands import those libraries which failed =
to=20
be imported because of the wrong sys.path variable.

I run the "script" in a very simple way (I do not know a better one for t=
he=20
moment): I just open the text file which contains the lines and paste the=
m=20
into the Python terminal window by "copy and paste". Not very elegant, bu=
t it=20
worked - at least for the 0.7.1 version.

***

Hope these hints can help you to take off with Scigraphica.

Randolf
