Hi,

Since you are installing from source, the easiest way would be to edit the Python script that installs all the base dependencies. To do so,

1) Open install_base_packages.py located in phenix-installer-dev-2306-source/modules/cctbx_project/libtbx/auto_build
2) Add 'configure_args.append("--enable_unicode=ucs4")' after line 644. That section just adds our flags to the configure step for installing Python. After editing, your section should look like,

configure_args.append("--enable-shared")
configure_args.append("--enable-unicode=ucs4")
configure_args.append("LDFLAGS=-Wl,-rpath=\$$ORIGIN/../lib")

3) Just run the Phenix install program (./install --prefix=<installation directory>) like normal and Python will be compiled with your new flag.

Let me know if you have any issues. Thanks!

Hi Billy

Thanks for your reply.
I installed phenix from source (phenix-installer-dev-2306-source.tar.gz).
And I used scientific linux 7.1 for my workstation.
I noticed that SCONS is adopted in the installation of phenix, and phenix will download a modified version of python (python_2.7.8_cci).
I think the problem can be solved by adding a flag "--enable-unicode=ucs4" in configuring Python-2.7.8_cci.
I'd appreciate if you can tell me how to modify the SCONS script file.

Hi,

Are you installing phenix from source or from a binary distribution? And which operating system are you using? I can give you the flags (in addition to the --prefix flag for installing into the base directory) for the configure step for either OS X or Linux.

You can basically install Phenix normally, and then recompile our Python from scratch with our regular flags and your extra flag.

Hi everyone

I've installed pymol and phenix on my scientific linux7.1 workstation.
I can launch pymol via the launching script($PYMOL_HOME/pymol) normally.
But when I launched pymol in phenix GUI, I got some error as followed:
*********************************************************************************************************************************
Traceback (most recent call last):
  File "/opt/PyMOL/modules/pymol/__init__.py", line 71, in <module>
    import pymol
  File "/opt/PyMOL/modules/pymol/__init__.py", line 521, in <module>
    import pymol._cmd
ImportError: /opt/PyMOL/modules/pymol/_cmd.so: undefined symbol: PyUnicodeUCS4_SetDefaultEncoding
*********************************************************************************************************************************
After STFW, I knew the problem is about unicode variant (UCS2, UCS4).
I also checked the configuration of two python.
For /bin/python (adopted by pymol)
>>> import sys
>>> print sys.maxunicode
1114111

And for $PHENIX_HOME/base/bin/python (adopted by phenix)
>>> import sys
>>> print sys.maxunicode
65535

My question is : How do I add the flag --enable-unicode=ucs4 in configuring Python-2.7.8_cci.


I'd appreciate if any reply on this.
