This doesn't work, although I don't yet understand why. PATH itself shouldn't be relevant here, as the app's installation directory should come up earlier in the dll search order anyway.

Ok, this may be the only long-term solution. However, it does reduce the usefulness of pre-built compiler binaries (to the point where they're *not* useful for dynamic builds??) > Another workaround, and probably the better, use only one distribution > of compiler. Why do you need to use both? Well, this is the real problem. I'm responsible for App 'foo'; App 'bar' isn't mine, and I don't compile it. There may be hundreds (Ok, 3 or 4) exes on my Windows box that I know nothing about, but which were build with MinGW, each of which has its own libstdc++. It doesn't matter (does it?) if some of them were compiled on mingw-w64, and some on mingw; what matters is if they require different libstdc++ versions. In my particular case, it so happens that the end-user runs 'foo' and 'bar' in the same flow, using a driver that I've written. >> 1 - I'm a bit hazy on why I've never seen a requirement for distributing >> various dlls before.

I was doing dynamic builds without problems.
