linking really large applications

[Thomas Matelich]

Sorry if this is the wrong category to post to, didn't see any that screamed "software development." I'm working on HPUX 11i, and am unable to link my application when I build it with debug information. My linker ident says:
/usr/ccs/bin/ld:
$Revision: 92453-07 linker linker ctr0.o B.11.16.01 030316 $
$Revision: 1.85 $

The libraries/objects I'm trying to link are primarily built with g++.

The error I get is:
/usr/ccs/bin/ld: Cann't mmap 12 bytes
/usr/ccs/bin/ld: Not enough space

It always says 12 bytes, and the odd spelling of "Cann't" is not mine.

I've changed my TMPDIR and TEMPDIR to a directory that has multiple GB of free space, increased maxdsiz to 0xC000000 and maxssiz to 0xC000000, and tried running it with no other apps running besides daemons.

I ran with -t and -v sent to the linker and the last things it printed before dying were:
Loading /usr/lib/milli.a(div_const.o):
Searching library /usr/lib/milli.a

Any kernel params or linker options or patches you might have would be most appreciated.

You are running a rather old version of ld. You should also rollback the size of maxssiz to 64MB or so because both the data and stack come from the same quadrant in 32-bit land so large stacks (even if not used) reduce the available heap for dynamic allocation. Mmap cal also be limited by swapspace.

By best advice is to add -Wl,+nommap to your CC makefile line so that the linker does not use mmap. This will result in slower links but mmap should no longer be a problem.
