I think you probably used a p4api built with the wrong version of gcc (most are 2.95 or similar).

Have you tried the gcc 3 version at:

ftp://ftp.perforce.com/perforce/r05.1/bin.linux3x86/

I should probably point this out in the docs.

Let me know if that fixes things.

Just a side note - there is a significant performance gain if your script is executing more than a few p4 commands using p4python.

I modified P4DTI to use p4python rather than the marshalling and a test harness run went from 120 seconds down to 20 seconds -

no other changes.

So, question:

I compiled P4Python on a random system, and get this error when I try to use it:

[preed at preed-lx ~]$ LD_LIBRARY_PATH="/exit14/home/preed/nethome/pylibs/lib/python" PYTHONPATH="/exit14/home/preed/nethome/pylibs/lib/python" python ./makeLabel.py Traceback (most recent call last): File "./makeLabel.py", line 3, in ? import p4 File "/home/preed/nethome/pylibs//lib/python/p4.py", line 17, in ? import P4Client ImportError: /exit14/home/preed/nethome/pylibs/lib/python/P4Client.so: undefined symbol: _ZTV10ClientUser

That symbol is not defined in any of the p4api static libraries, and I compiled P4Python.so with a relatively recent version of gcc, so I'm not surprised that the C++ name mangling semantics may have changed.

Do I have to find a SuSE box (what p4/p4d/p4api were compiled on) and compile this there?
