did it work for you ?

thomas:
Before: "0 minutes 5 seconds", after: "0 minutes 0 seconds".
Hmm.... unquestionable. So now I have to figure what I am doing wrong.

The only two differences I see are you use // instead of /**/ for the top comment and you include everything via one file. Will try either of these and see what it does. Thank you :)

forget that, the lines should be deleted, they are commented because i tried a while and several ways until i got it working...

That's the important one, only one header-file (in this case precomp.h)can be pre-compiled! of course there can be added more headers if your project grows and needs additional headers...


Did you manage to produce the precomp.h.gch ? (size about 43 MB)
After this file exists in the same directory where precomp.h also resides, you can recompiling your project using the precompiled header-file.

It is important to use the -Winvalid-pch  compiler option in order to get information if the precompiled header could be used or not.
If there are warnings regarding the precompiled header,
NOT ALL compiler options were the same when pre-compiling the header-file as they are now at the time of compiling.

thomas:
Got it working now, thanks :) It was indeed the "only one header file" thing.

Now it takes 5 seconds instead of 20 seconds compiling cb::svn. 75% saved :)
