Hi Alastair, what was the exception in the is_64bit_architecture function? Could you send the stack trace? Cheers, Oleg. Date: Sun, 9 Jun 2013 18:04:09 -0700 From: [email protected] To: [email protected] Subject: [cctbxbb] build problem on ubuntu 12.04 Hello, is the current cctbx build (2013_02_27_0005) known to be buildable on Ubuntu ? I tried "perl cctbx_bundle.selfx" without success. After some poking about I found an exception raised in the platform.architecture() call in env_config.py/is_64bit_architecture(). Modifying the function to simply return False allowed the build to complete (log attached).This is on 12.04 with stock python 2.7.3 and the "platform.architecture()" call works as expected in a simple test. thanks, Alastair _______________________________________________ cctbxbb mailing list [email protected] http://phenix-online.org/mailman/listinfo/cctbxbb
