ucs2 and ucs4 python

[Alan Kesselmann]

Hello

I tried using one compiled library and got this error:
ImportError: /home/alan/Downloads/pdftron/PDFNetC64/Lib/
_PDFNetPython2.so: undefined symbol: PyUnicodeUCS2_AsUTF8String

I googled around and found some info about the meaning of the error.
The creators of PDFNet suggested i install UCS2 python next to my UCS4
version to try their library.

Can someone point me towards a resource or two which will tell me how
to do this - im not very good with whole linux/servers stuff. Im using
ubuntu linux - if that makes any difference.

Did not test, but this is the direction I would take:
* Download Python sources
* Open Terminal
* Run the following commands in the Terminal window
- sudo apt-get build-dep python
- tar -xjf Python-2.7.3.tar.bz2
- cd Python-2.7.3
- ./configure --prefix=/opt --enable-unicode=ucs2 && make
- sudo make install
* Now you should have /opt/bin/python with ucs2

Thanks for reply

And it seems to work... When i type in
/opt/bin/python
import sys
sys.maxunicode

then i get the desired answer - 65535

But it seems the work only begins now, because i cant use other python
libraries now with this version of python and i probably have to
install them all again somehow...

But thanks for your help

There is one problem though...

when i start script with shebang like
#!/opt/bin/python

and then try to run the script i get:

/opt/bin/python^M: bad interpreter: No such file or directory

/opt/bin/python
/opt/bin/python2
/opt/bin/python2.7 all start this new version of python, but none of
those work in shebang

Your script has CRLF end-of-lines. Change it to plain Unix LF.

Thanks but i have no idea what that means or how to achieve that.

No need to answer that now, Dave explained this to me via personal
reply.

Thanks man!

And thanks again to everybody else
