Lots of Error Messages Upon Invoking "from pylab import *"

Hi Angelo,

I have faced a similar problem on using “from pylab import *”

but not exactly the same,

" matplotlib._ns_transforms.so:
undefined symbol: _ZNSs4_Rep20_S_empty_rep_storage "

And I have found that this problem is deep rooted with gcc level and
not with matplotlib,

The python which you are using should be compiled with gcc level 3.4.6
(or may be higher, I have tested with gcc-3.4.6),when I compiled it gcc-3.2.3
on redhat linux I was getting this error

Hope it helps

I am using kanotix which is a very stable debian sid system. I
intalled the matplotlib package from the debian database
successfully. It may have pulled in python 2.4 as well. Please see
what happens when I use the command “from pylab import *” within

Can someone please help me with this?

Kind regards,
