Why does a build take so long?

[WSinc]

This projectI am doing now usually builds in less than a minute.

Its not very large, maybe 12-15 routines MAX.

But sometimes for no apparent reson, it takes over 20 minutes.

Why would the SAME project be inconsistent with itself?

I turned off the spyware detector, but that has no effect.

could anything lese be causing this?

Is there one file in particular that takes a long time to compile, or are all the compiles slow when this happens? Rather than a spyware detector, you might want to try disabling antivirus protection, though I doubt it would slow down things that much.

The compiles aren't hanging anyhing up.
Usually a complete rebuild compiles everything in less than a minute,
but the LINK step is what's hanging up.

This occurs about 10 percent of the time.

Just enought to really be annoying ...

and then I get, "failed to write manifest" whatever that means.

I have seen this too in VS2008 but not as often as 10%. If you hit Ctrl+Break and then re-start the build, does it go quick again?

sounds similar to what I have,

but I didn't get any error.

Ctl + Break sometimes does it more quickly.
But I have to kill the VS entirely, then start from scratch.

What does it mean:
"Can't write manifest ?"

The compiles take no time at atll. It's the LINK step that hangs up.
