On HP-UX-11.x the maximal data size (allocated data) of a 32 bit program is
|
|
64 MB.
|
|
|
|
One solution is to build a 64 bit binary, for those the default process memory
|
|
limit is 1 GB.
|
|
|
|
64bit binaries can be created with
|
|
|
|
cc +DA2.0w
|
|
cc +DD64
|
|
|
|
if you have the HP C-ANSI-C compiler.
|
|
|
|
To compile in 64 bit mode, first call ./.clean then call
|
|
|
|
make COPTX=+DD64 LDOPTX=+DD64
|
|
make COPTX=+DD64 LDOPTX=+DD64 install
|
|
|
|
|
|
If you have an older GNU gcc, you need a 64bit compiled gcc. Older GNU gcc versions
|
|
are not capable of switching, so you need a separate compiler installation for either:
|
|
|
|
l1:/u/usr/merijn 102 > file /usr/local/pa*/bin/gcc
|
|
/usr/local/pa20_32/bin/gcc: PA-RISC2.0 shared executable dynamically linked -not stripped
|
|
/usr/local/pa20_64/bin/gcc: ELF-64 executable object file - PA-RISC 2.0 (LP64)
|
|
l1:/u/usr/merijn 103 >
|
|
|
|
With a newer GCC, you may call ./.clean then call:
|
|
|
|
make COPTX=-mlp64 LDOPTX=-mlp64
|
|
make COPTX=-mlp64 LDOPTX=-mlp64 install
|
|
|
|
|
|
The other way is to alter some kernel parameters which require a reboot.
|
|
The default kernel parameter seem to look like:
|
|
|
|
Kernel param. Value
|
|
maxdsiz 67108864
|
|
maxdsiz_64bit 1073741824
|
|
maxfiles 200
|
|
maxfiles_lim 2048
|
|
maxssiz 8388608
|
|
maxssiz_64bit 8388608
|
|
maxswapchunks 3250
|
|
maxtsiz 67108864
|
|
maxtsiz_64bit 1073741824
|
|
|
|
The important one is maxdsiz, 64 MB is the default and it is rather low.
|
|
There is some information page at http://www.uwsg.iu.edu/hp/hpux-tune.html#maxdsiz
|
|
and they recommend to increase it to 1.9 GB. Sounds extreme.
|
|
|
|
At http://forums.itrc.hp.com/cm/QuestionAnswer/1,,0x08afe7613948d5118fef0090279cd0f9,00.html
|
|
they recommend 500 MB.
|
|
|
|
maxssiz shouldn't be a problem either since it has to do with swap and such as
|
|
storing arrays and recursion etc.
|
|
|
|
If you like to know how to create 64 bit binaries on Solaris, please
|
|
read README.compile. I hope this helps. If you found the right way for HP-UX,
|
|
please send me a mail.

The Schily makefile system usually should be able to find the best C-compiler
|
|
on HP-UX automatically. If it does not work, here is a way force to use a different
|
|
compiler.
|
|
|
|
|
|
You may compile with the HP ANSI C-Compiler using:
|
|
|
|
make CCOM=cc
|
|
|
|
To compile with the free K&R C-compiler call:
|
|
|
|
gmake CCOM=cc 'COPTS= '
|
|
or
|
|
smake CCOM=cc 'COPTS= '
|
|

HP-UX SCSI hints:
|
|
|
|
Note that there are no device nodes for userland SCSI on HP-UX,
|
|
you have to call the included shell script MKNOD.hpux first.
|
|
|
|
If you own a HP-9000-800 series machine, you need to install
|
|
the file MKNOD.hpux-800 in the /etc init shell script directory
|
|
in order to call it after each boot.
|
|
|
|
This script will create the files in /dev/scsi/... and /dev/rscsi/...
|
|
The permissions will be set to read/write for root only.
|
|

HP does not handle CD-ROMs as well as it should. On the HP have a look at
|
|
the man pages for
|
|
pfs
|
|
pfsd
|
|
pfs_mount
|
|
and anymore that they refer too.

As of Jun 2002, there are some patches available to HP-UX 11.00 and 11i that
|
|
prevent the need for pfs, and these are highly recommended, since Rock-Ridge
|
|
extensions are now supported from the kernel level.
|
|
|
|
For 11.00:
|
|
|
|
a5:/ 103 # swlist | grep -i rock
|
|
PHCO_26449 1.0 Add Rock Ridge extension to mount_cdfs(1M)
|
|
PHKL_26448 1.0 Y2k; Rock Ridge extension for ISO-9660
|
|
PHKL_26450 1.0 Rock Ridge extension for ISO-9660
|
|
a5:/ 104 #
|
|
|
|
PHKL_26448 is not recommended, but I never had any trouble with it. I still
|
|
have to install PHKL_28060 over PHKL_26448
|
|
|
|
PHKL_28060 1.0 Y2k; Rock Ridge extension for ISO-9660
|
|
|
|
For 11i:
|
|
|
|
PHKL_28025 1.0 Rock Ridge extension for ISO-9660
|
|
PHKL_26269 1.0 Rock Ridge extension for ISO-9660
|
|
PHCO_25841 1.0 Add Rock Ridge extension to mount_cdfs(1M)
|
|
|
|
I don't have 11i (yet), so I got this from HP-UX' patch database.
|

The problem is that they did /not/ enable RR by default, but made it a mount
|
|
option. D'uh! But you can add it in /etc/fstab, and never worry again :)
|
|
|
|
a5:/ 104 # grep cd /etc/fstab
|
|
/dev/cd0 /cdrom cdfs ro,rr,noauto 0 0
|
|
a5:/ 105 #
|
