Question

How do YOU reduce compile time, and linking time for VC++ projects (native C++)?

Please specify if each suggestion applies to debug, release, or both.

Answer 1

Another useful technique is blobbing. I think it is something similar to what was described by Matt Shaw.

Simply put, you just create one cpp file in which you include other cpp files. You may have two different project configurations, one ordinary and one blob. Of course, blobbing puts some constrains on your code, e.g. class names in unnamed namespaces may clash.

One technique to avoid recompiling the whole code in a blob (as David Rodríguez mentioned) when you change one cpp file - is to have your "working" blob which is created from files modified recently and other ordinary blobs.

We use blobbing at work most of the time, and it reduces project build time, especially link time.
