Platform Notes (Compaq Tru64 UNIX)

Port Status

Compaq Tru64 UNIX is a Tier 2 Port

Verified Releases

• FreeM 0.62.3 (27 Mar 2025)
• cvs-current (26 Mar 2025) (builds and runs cleanly, but will use global-backed SSVNs)

FreeM 0.62.2 builds, but errors out when launching the daemon:

freem [FATAL]:  memory allocation failure in symtab_init [errno 0 Successful]

There is an issue on this at https://bugs.coherent-logic.com/view.php?id=16

Testing Details

We build and test the Tru64 UNIX port on a system with the following specifications:

• Alpha EV67-based host
• Compaq Tru64 UNIX 5.1b
• GNU gcc v4.7.7
• GNU autoconf 2.71
• GNU automake 1.16.4

This port should theoretically run on DEC OSF/1 or Digital UNIX, given a compatible GNU toolchain, but we do not have the resources to test such configurations.

Required Kernel Tuning

For the default daemon configuration, you will need a kernel shm_max parameter of at least 16795968. We recommend 17000000.

To apply an shm_max of 17000000, you will need to do the following:

• Gain root privileges on your system
• Create a file called "pstanza" with the following data:

ipc:
    shm_max = 17000000

• If no shm_max parameter exists in /etc/sysconfigtab:

# sysconfigdb -a -f pstanza ipc

• If a previous shm_max configuration exists:

# sysconfigdb -m -f pstanza ipc

• Reboot the system
