Hello everyone, I have just installed sage 3.2.3 to a directory that is being shared among various AMD- and Intel-based Linux workstations. In case anyone else wants to do the same, I will briefly summarize what I did.
i) Following advice from the friendly folks at #sage-support, I selected two build machines, one for each architecture. I made sure to use older machines to avoid generating e.g. SSE3 instructions. ii) After re-exporting the software directory (we use /usr/local) read- write to these two machines, follow the documentation at http://www.sagemath.org/doc/inst/node8.html . Actually, I wanted to avoid the NFS overhead, so I did not build in place, but in a local directory instead. Afterwards, I copied that directory to its place on /usr/local via tar and scp. Note that step 3 from the docs (make test) should be performed after copying. iii) In step 4, copy to sage-intel and sage-amd rather than sage. iv) Create a wrapper script to detect the architecture. Mine is a bit simplistic, but should work (unless you use it on a non-AMD, non-Intel machine, where it exits silently). It looks like this: --------------------------------------------------------------------------- #!/bin/sh grep GenuineIntel /proc/cpuinfo >/dev/null && /usr/local/bin/sage- intel "$@" grep AuthenticAMD /proc/cpuinfo >/dev/null && /usr/local/bin/sage-amd "$@" --------------------------------------------------------------------------- A. --~--~---------~--~----~------------~-------~--~----~ To post to this group, send email to sage-support@googlegroups.com To unsubscribe from this group, send email to sage-support-unsubscr...@googlegroups.com For more options, visit this group at http://groups.google.com/group/sage-support URLs: http://www.sagemath.org -~----------~----~----~----~------~----~------~--~---
