Hi,

I want to recompile Qt4 from source and would like to force the speed optimization and SSE3. Anyone knows how to do it?

I'm using Qt 4.3 and Visual Studio .NET 2003

Thanks,

Qt should be optimized for speed by default when you build it in release mode. As for other optimizations, use the regular approach for your compiler.

You'll want to look in the mkspecs for your compiler..
