Turning on optimization virtually _always_ results in the compiler needing more resources. How much more depends on the size, complexity, and ' optimizability' of the code being compiled. The simple fix for your problem is to add swap space to the system. swap space does -not- have to be in a dedicated partition, see 'man swapon' for how to use a -file- as temporary swap space. I had done it if disabling the optimization wouldn't have changed anything. The main problem was that I didn't know how much swap I had to add. Right now I have an updated system but I will have a look at how much RAM this takes using -O2. Note: if you find someting that won't compile, given a combined 4 gigs of RAM and swap space, and the build isthe only thing running beyond core system services, *then* you've got the basis for 'good' PR filing.

It's hard to say whether this is really a bug or not - I still think your overall memory is low - 1 GB of RAM should be a supported configuration, but that assumes a decent amount of swap - I'll bet sysinstall's recommended partitioning would give you 2 GB. I still refuse to think 1GB is low ;) though I could be wrong. Try mailing the maintainers (ge...@freebsd.org) and see what they say. I'll do it. Thanks for your advices.

One gig of RAM is not the problem. 1.25 gig total of VM _is_. I have some stuff I run on an *OLD* (next year it will be old enough to vote :) 80486 box with only 96 megs or actual RAM, but 2gig of VM. Compiling is a complicated process, all the more so with the features that have been added to the languages over the years. *and* the need to support multiple character sets, -especially- those that don't fit in an 8-bit enumerationn. these tHings, along with improvements in code optimization techniques, have combined to radically increae the footprint that a language compiler requires these days. Factor in the increasing size of the applicaiton modules themselves, and it should be -no- surprise that compilation of an app of significant complexity has a large memory footprint. I've got a FBSD 7.2 box that shows 80 megs of 'actively used' VM with the basic system services running. I've got a -dinosaur- running a *BSD releae from th prior century, running a the same stuff, -plus- a webserver, in only 16 megs of active memory. 'code bloat' is a fact of life. ___ freebsd-questions@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to freebsd-questions-unsubscr...@freebsd.org

libxul compilation problem
Hi, I have a ports version fetched on Oct 13th. I wanted to update all the ports I have installed. In order to do that I run: swap_pager_getswapspace(16): failed swap_pager_getswapspace(12): failed swap_pager_getswapspace(16): failed swap_pager_getswapspace(12): failed swap_pager_getswapspace(16): failed swap_pager_getswapspace(12): failed ... ... swap_pager_getswapspace(3): failed swap_pager_getswapspace(3): failed The process being killed is cc1plus while compiling libxul. I'm running a stock 8.1-RELEASE GENERIC kernel on amd64 platform. The machine has 1Gb of physical memory and 256MB for swap (I have had this setup for quite a long time and have always kept my system up to date using the ports infrastructure without problems). Do I need any special setup to compile this package? Maybe any systcl vm.* should be tunned?
