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. Alan

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 Alan

That's a carriage return, hex(0d). Unix/Linux use a single linefeed (hex(0a)) at the end of the line. At some point, you probably edited this file with a Windows (aka DOS) editor, and it used the CRLF form (hex(0d0a)), carriage return/line feed at the end of each line. Your Linux text editor probably has a menu option to convert them back to simple linefeeds, but if not, your Linux/Unix probably has a utility dos2unix which can do the job.

how are you editing the files? If nothing else, run the script through
dos2unix or equivalent before executing.

install packages directly and automatically from the Python Package Index
(PyPI), including any dependencies.
Even better, use "virtualenv" to create a local copy of your installation
and then install packages into that. This allows you to use completely
separate environments of the same Python installation, which can be very
handy for testing.
