Hi all,
I’ve successfully used version 0.52. Yesterday I installed v0.64 on my RH9
linux box. The build and install went OK. However, when I try to play with
it, I get:
`The import of the numeric version of the _transforms
module, _nc_transforms, failed.
This is either because numeric was unavailable when matplotlib was compiled,
or because a dependency of _nc_transforms could not be satisfied.
If it appears that _nc_transforms was not built, make sure you have a working
copy of
numeric and then re-install matplotlib. Otherwise, the following traceback
gives more details:
Traceback (most recent call last):

`
I tried many things in the setupext.py. Freetype is correctly installed and
Numeric is in /opt/Numeric23.1. I added this to the script… because the
way it appends include/lib path seems a little buggy to me.
`def add_ft2font_flags(module):
'Add the module flags to build extensions which use gd'
....
module.include_dirs.append('/usr/local/include/freetype2/freetype')
....`
and
`def add_agg_flags(module):
'Add the module flags to build extensions which use agg'
# before adding the freetype flags since -z comes later
module.libraries.append('png')
module.libraries.append('z')
add_base_flags(module)
module.include_dirs.extend(['src','agg22/include', '.'])
module.include_dirs.append('/opt/Numeric-23.1/Include')
# put these later for correct link order
module.libraries.extend(['stdc++', 'm'])`
I also tried other things. I still get the same error message. I’m stuck
! Has anyone encoutered this problem ?
solved it ? Shall i install a newer version of Numeric ? In an other place
than /opt ?
Any help would be geatly appreciated !
