I am almost sure this has been addressed before, so you can go after me for insufficient googling. However,
1. Is there any *significant* advantage in using 64-bit CCP4 binaries (primarily speed)? 2. IIUC, the standard CCP4 download results in 32-bit binaries being run on a 64-bit system. Works for me (except for the weird iMosflm issue), but given that 64-bit OS is becoming more and more common, isn't it time for 64-bit binaries option? The answer, of course, is no if you answered no to 1 above. And to make this post completely incomprehensible: It seems I have compiled 64-bit version on Ubuntu 11.04 just fine, but several examples fail, and all points to clipper libs. Could this be because I have clipper libs installed from ubuntu repositories and the solution is to use --disable-clipper option when configuring? I am trying this now but maybe someone can point me in the right direction. -- "Hurry up before we all come back to our senses!" Julian, King of Lemurs
