Linux And HP-UX?

I went looking around and found that mklinux is supposed to run on HPPA (which is the type of CPU my HP-712/100 has). I haven't been able to find any useful information on how to go about this, and I'd be very happy to hear comments and tips from anyone who uses Linux on HP's regularly."

  1. You might be able to make it run... by bconway · · Score: 2

    but why would you want to? The MKLinux project has had a lot of problems in the past, and when the other option is HP's UNIX, there's really no reason to switch. Sure, it might not stand up as well to Digital UNIX or Solaris, but it has all the qualities of a professional UNIX, and I think you'd be severely disappointed if you went with MKLinux. Just my $0.02.

  2. Linux/PA-RISC project by Lish · · Score: 2
    I am currently working with the Linux/PA-RISC project, a native port of Linux to PA. The kernel is still definitely "developer-release," but I can boot it on my 712/80 and do some basic stuff. If you'd like to try it out and/or contribute to the project the web site is www.thepuffingroup.com/parisc. Lots of info there.

  3. HP-UX by Alex+Belits · · Score: 3

    HP-[s]UX is a very weird system, however I doubt that mklinux will be any better on HP-PA. I can offer just few tips that can make things easier.

    1. Use gcc instead of native compiler, especially for C++ -- last time I have seen their native C++ compilers, they didn't work with HP-UX include files, returned "Assertion failed" and otherwise behaved in some braindamaged manner.
    2. When writing for HP-UX look at the manual page for mallopt() function -- malloc() on HP-UX has very inefficient defaults, and I had horrible performance of C++ programs until I've set its limit for "small blocks".
    3. Install your favorite shell, gnu tools, widgets library, etc. -- they will all compile on HP-UX, and you will need them.
    4. Fix terminal settings if you don't like them, and put them into login scripts.
    5. Use Linux box as X terminal with its own window manager and ssh, or compile your favorite window manager on HP-UX box -- CDE sucks.
