What python version are you using? Make sure it's 2.7.

Yes, i'm using 2.7.3 from the repository.
I do not have installed csound6 but i have added the build directory
in PYTHONPATH and set OPCODE6DIR to same directory.
Maybe this is wrong?


Thanks,
ciao,
francesco.

I wouldn't think so. Try this command with the python module (_csnd6.so).

coltrane:debug victor$ nm _csnd6.so | grep 'init_csnd6'
0000000000075589 T _init_csnd6

If it prints out like above _init_csnd6, then the symbol is there OK.

yes, then it's a build problem. This function is defined in the python_interface.cxx file that SWIG generates:

coltrane:interfaces victor$ grep init_csnd6 python_interfacePYTHON_wrap.cxx
#  define SWIG_init    init_csnd6

you can start checking that.

python_interfacePYTHON_wrap.cxx 

#  define SWIG_init    init_csnd6

Well, that is the correct thing. I noticed that the _csnd6.so in the interfaces directory does not contain _init_csnd6. The one on the top-level build does.

Ok, Your first reply was the right!
My build used python3, that i did not know to have installed.
Now it's ok.

I'm guessing Csound6 will works with Python 2, maybe it's possible 
to set cmake for searching for the correct Python version?

Thank You and sorry for the noise.
ciao,
francesco.
