Error: can't vm_allocate() buffer for output file (os//kern) no space available

Hello,

When linking large static libraries (the OpenMW library I tried to link was over 2GB), I receive this error.
I believe I am hitting this error because of 32 bit addressing limitations.

Is darwin-xtools only built for 32-bit PPC at the moment? Would it be non-trivial to fix this, or is this some hard limitation that we're going to have a hard time working around?

Could you provide some more information about the system you're trying this on?

This is a PowerMac G5 Quad with 12GB of RAM.

These were my memory resources at the time this command failed:

I have over 40GB of free storage space.

Unfortunately even when trying to move back to RelWithDebInfo build which succeeded previously, it now fails. I can no longer build this project despite making no changes to the code and reverting to a known good build configuration.

I figured out that my issue was stemming from a build configuration change on my end that I missed, causing the static library to become much larger and trigger this error. Disabling the "Unity build" in OpenMW causes the static library to swell in size regardless of build configuration.

I'm sure this is not a very common issue to run into, but it has been seen before with debug builds of nodejs, mongodb and qtwebkit, Any fixes (or advice for me if I wanted to try fixing it) would be welcome.

Please provide the output of uname -a and sw_vers, and a link to the "OpenMW" project you are trying to build (yes, one could search, but it's a short enough name that disambiguation might be necessary, so it'd be better if you could just link what you're using)
