Hi Phenix, We are trying to upgrade Phenix on our Linux box running RHEL 6.3, kernel 2.6.32-279.14.1.el6.x86_64. I have attempted to install the Centos 5 build and I get an error message during installation: Configuring Phenix components... Traceback (most recent call last): File "./bin/install.py", line 262, in <module> installer(sys.argv[1:]).install() File "/home/public/packages/phenix-installer-1.10.1-2155-intel-linux-2.6-x86_64-centos5/lib/libtbx/auto_build/install_distribution.py", line 185, in install self.install_from_binary() File "/home/public/packages/phenix-installer-1.10.1-2155-intel-linux-2.6-x86_64-centos5/lib/libtbx/auto_build/install_distribution.py", line 295, in install_from_binary self.reconfigure(log=log) File "/home/public/packages/phenix-installer-1.10.1-2155-intel-linux-2.6-x86_64-centos5/lib/libtbx/auto_build/install_distribution.py", line 460, in reconfigure call(args=args, log=log, verbose=self.options.verbose) File "/home/public/packages/phenix-installer-1.10.1-2155-intel-linux-2.6-x86_64-centos5/lib/libtbx/auto_build/installer_utils.py", line 81, in call raise RuntimeError("Call to '%s' failed with exit code %d" % (args, rc)) RuntimeError: Call to '/home/public/packages/phenix-1.10.1-2155/base/bin/python /home/public/packages/phenix-1.10.1-2155/modules/cctbx_project/libtbx/configure.py --current_working_directory /home/public/packages/phenix-1.10.1-2155/build --command_version_suffix 1.10.1-2155 phenix phaser solve_resolve labelit' failed with exit code -11 When I attempt install the CentOS6 build I can install Phenix, but when I try and launch it I get a different error message: Traceback (most recent call last): File "/home/public/packages/phenix-1.10.1-2155/build/../modules/phenix/wxGUI2/command_line/main.py", line 23, in <module> run(sys.argv[1:]) File "/home/public/packages/phenix-1.10.1-2155/build/../modules/phenix/wxGUI2/command_line/main.py", line 16, in run from wxGUI2 import App File "/home/public/packages/phenix-1.10.1-2155/modules/phenix/wxGUI2/App.py", line 15, in <module> import wx File "/home/public/packages/phenix-1.10.1-2155/base/lib/python2.7/site-packages/wx-2.8-gtk2-unicode/wx/__init__.py", line 45, in <module> from wx._core import * File "/home/public/packages/phenix-1.10.1-2155/base/lib/python2.7/site-packages/wx-2.8-gtk2-unicode/wx/_core.py", line 4, in <module> import _core_ ImportError: /home/public/packages/phenix-1.10.1-2155/base/bin/../lib/libXrender.so.1: undefined symbol: _XGetRequest Should I give up and attempt to compile from the source, or is there a fix for these issues?
