Re: pyROOT on Mac OS X Snow Leopard

Hi again,

I re-compiled ROOT in 64-bit (I needed to disable 'xrootd'), and now python goes further in importing ROOT but I get the following error:

ImportError                               Traceback (most recent call  

/Users/froncaro/<ipython console> in <module>()

/root/lib/root/ROOT.py in <module>()

      84 sys.setdlopenflags( 0x100 | 0x2 ) # RTLD_GLOBAL | RTLD_NOW
      85
---> 86 import libPyROOT as _root

      87
      88 # reset dl flags if needed

ImportError: dlopen(/root/lib/root/libPyROOT.so, 2): Symbol not found: _FT_Done_Face

   Referenced from: /root//lib/root/libGraf.so    Expected in: flat namespace
  in /root//lib/root/libGraf.so

Indeed, the which python gives me:

/usr/bin/python: Mach-O universal binary with 3 architectures /usr/bin/python (for architecture x86_64): Mach-O 64-bit executable x86_64

/usr/bin/python (for architecture i386):	Mach-O executable i386
/usr/bin/python (for architecture ppc7400):	Mach-O executable ppc

What can i do?

thanks,
Federico
