Memory limit

[jaax]

Hi all,

I have installed NetBSD 5.1 amd64 on my laptop and it reboot every time.

I had the same problem under FreeBSD and the solution was to set a knob hw.physmem=3G in the file /loader.conf.

But, i have not find this entry under NetBSD.

How can i limit the memory on my laptop ?

Thanks a lot

In the source of the kernel, we have the possibility to limit the max size of physical memory.

options         PHYSMEM_MAX_SIZE=3072   # max size of physical memory (in MB)

But, when i want to recompile the new kernel, i have this error :

#   compile  MYKERNEL/machdep.o

How can i do to remove this warning ?

Thanks

Warnings issued by the compiler are not errors. For example I also get warnings when I compile Bernstein's daemontools and djbdns on OpenBSD, but the compiler just continues and the programs run fine..

In your case the problem is cc1: warnings being treated as errors. For something this specify to the NetBSD kernel, you probably get more response at one of the NetBSD mailing lists.
