Memory Shortage When Compiling Inside X/qt, How to let X/Qt fully use the swap space Options

[xjqian]

I tried to natively compile a GUI program in X/Qt. However, during the make process, it often popped up a window saying that memory of the workspace was too low (suggesting me to close X/Qt). Frequently X/Qt was automatically shut down due to insufficient memory. Although I did enable 256Mb swap space, it was hardly used by more than half as I monitored.


Anybody had experience with this. Is such a compiling prohibitive in nature due to Z's memory limitation?

So I believe that such warning shows up whenever memory usage approachs 64MB limit (i.e.the physical RAM). It's ok if swap speed can catch up with the memory demand at the verge of overflow. Otherwise, X/Qt will crash.

I'm hardly the expert, but I wonder if you reduce the priority of the compile task very low, the system might be able to keep up? That's the "nice" command, right?

Also, do you think it matters where you keep your source and output files? Might be worth moving them around; the different I/O rates could have an effect.

Try compiling something smaller?

Still, these sound like band-aid approaches. The OS should suspend applications automatically while it is keeping the swap situation and memory allocation correct, seems to me. I'm no kernel hacker, though.
