Mingw very slow on windows

[elsheikhmh]

Hi,
I use Qt 4.2.3 open source edition, Mingw 3.4.2 (mingw as installed by Qt bundle qt-win-opensource-4.2.3-mingw.exe), on Windows 2000 SP4.
mingw is very slow in compilation. A process called cc1plus.exe is eating up to 100 MB during compilation.
What's wrong with my installation?

Thanks in advance,
Mustafa

But that is the compiler process itself.
Not much you can do about that, I'm afraid.

hi,
I mean it's very very slow. Is mingw known to be very slow? I use mingw with GLUT and it's not that bad as with Qt.
I read about speeding up compilation by static linking with Qt. but I've not idea how to do that.

[marcel]

Static linking with Qt means that a significant part of Qt will be included in your app.
The size will also increase significantly.
You should think about it before doing it.

at least i can do it during the development phase.
how can i do it?

The GNU compiler (which is mingw) is notoriously slow. Turning on precompiled headers will help, but the compilation itself is significantly slower than the MS or Intel compilers. Make also slows some stuff down. Using the -j2 or -j4 option to GNU make can be a significant improvement.

But if all else fails, just go start a pot of coffee when you launch a build.

I'll try solutions on trolls list, and -j2/4 options.
Thanks
