Slightly OT: How to build COM dlls in parallel

[Andreas Tscharner]

Hello World,

This question might be slightly off-topic, but I figure that Jenkins
users may have had this problem (and probably a solution) before:

We use feature branches to develop new features on out product. Each
feature branch has a build job on Jenkins. Our product builds quite a
few COM DLLs which need other registered(?) TLB od DLLs. If the
interfaces differ and more than one build run in parallel the interfaces
and binaries get mixed up.
I suggest other users have had the same or similar problems too? How did
you solve it?

TIA and best regards
Andreas

If you think you have the solution, the question was poorly phrased.

COM interfaces with the same IID need to be identical all of the time.

One customer of mine has a large project with changing interfaces, and
automatically generates a new UUID on checkin if an interface changed.
