Out of memory error when compiling perl MQSeries module on PA RISC

[Iain Soedring]

This is on 11.23, when running 'install MQSeries' from CPAN, it seems to hang on this:

cc -c -I"/opt/mqm/inc" -I../include -D_POSIX_C_SOURCE=199506L -D_REENTRANT -Ae -D_HPUX_SOURCE -Wl,+vnocompatwarnings +Z -DUSE_SITECUSTOMIZE -DNO_HASH_SEED -D_LARGEFILE_SOURCE -D_FILE_OFFSET_BITS=64 -fast +Onolimit +Opromote_indirect_calls +DAportable +DS2.0 -DVERSION=\"1.32\" -DXS_VERSION=\"1.32\" +Z "-I/opt/perl_32/lib/5.8.8/PA-RISC1.1-thread-multi/CORE" -DMQ_CMVC_LVALUE=\"p600-210-100825\" constants.c
cc: warning 487: Possibly incorrect message catalog.

After half an hour or so it stops with an out-of-memory error:

cc: procedure constant_numeric(): error 6350: Out of memory. Check kernel maxdsiz parameter and swap space configured. (6350)
cc: procedure constant_numeric(): error 6350: Not enough space [errno=12]
Out of memory while reading in symbol table of /opt/ansic/lbin/ccom

I have already increased the swap space but to no avail, and I doubt this is the problem.

Hi:

> I have already increased the swap space but to no avail, and I doubt this is the problem.

And have you assessed your 'maxdsiz' setting as the error suggests? What does 'swapinfo -tam' show just before the out-of-memory error?

Regards!

Thanks for the reply, and yes, I checked maxdsiz.

'swapinfo -tam' showed this BEFORE running the compile:

Mb Mb Mb PCT START/ Mb
TYPE AVAIL USED FREE USED LIMIT RESERVE PRI NAME
dev 4096 0 4096 0% 0 - 1 /dev/vg00/lvol2
reserve - 394 -394
memory 4094 1365 2729 33%
total 8190 1759 6431 21% - 0 -

And this near the end:

Mb Mb Mb PCT START/ Mb
TYPE AVAIL USED FREE USED LIMIT RESERVE PRI NAME
dev 4096 0 4096 0% 0 - 1 /dev/vg00/lvol2
reserve - 791 -791
memory 4094 1368 2726 33%
total 8190 2159 6031 26% - 0 -

Have you watched the memory usage in top?

What is it?
If you have maxdsiz at 1 Gb and you have plenty of swap, your only choice is to stop optimizing, remove: -fast +Onolimit +Opromote_indirect_calls
Just use -O.

Or port to Integrity where the compiler is a 64 bit application.

Removing the optimizations did the job, many thanks (although I needed to download the package and hack the Makefile manually, couldn't see how to do it through the automated CPAN process).
