[GRASS-user] v.digit under wxGUI

GRASS GRASS user
1

Hello,

Compiling grass64 on Ubuntu Hardy for 64bit system, I got this error
when running v.digit under wxpython interface :

/usr/local/lib/libgdi.so: undefined symbol: Py_InitModule4

Already pointed in this thread
http://lists.osgeo.org/pipermail/grass-dev/2008-May/037763.html

but I can't catch any solution in the links proposed by Markus.

Does anyone have a solution ? or should I give up on my 64bit
architecture ?

Thank you,
Vincent.

No need to give up on 64bit, I am using it like many others here.

Please post the result of
file /usr/local/lib/libgdi.so

I get
/usr/local/lib/libgdi.so: symbolic link to
`/usr/lib64/python2.5/site-packages/wx-2.8-gtk2-unicode/wx/_gdi_.so'

As you see it links to the 64bit version of _gdi_.so.

Perhaps you linked the 32bit version?

OK,

so in order to fully enjoy the wxpython GUI on an 64 bit architecture
(especially the wxdigit module) one should first read carefully the
README file located in the your_grass_source_location/gui/wxpython
directory.

The section named "7 - VECTOR DIGITIZER" tells you to create a symbolic
link to a wx library :

        sudo ln -s `locate _gdi_.so` /usr/local/lib/libgdi.so

The command locate _gdi_.so may points towards the 32 bit library and
ignore (?) the 64 bit libs path (/usr/lib64/...), so it fails. In my
configuration I had to type :

        sudo ln -s /usr/lib64/python2.5/site-packages\
        /wx-2.8-gtk2-unicode/wx/_gdi_.so /usr/local/lib/libgdi.so

And it worked !

Excellent.

Please post a short note to the list so that the next one
in the trap finds it :slight_smile:

thanks
Markus

Ouch, you are right! I have a pure 64bit box here...

In my configuration I had to type :

       sudo ln -s /usr/lib64/python2.5/site-packages\
       /wx-2.8-gtk2-unicode/wx/_gdi_.so /usr/local/lib/libgdi.so

And it worked !

It needs to be conditionalized upon
$HOSTTYPE

Here:
echo $HOSTTYPE
x86_64

I'll update the README accordingly.
