However, running pvlist within msys causes it to just fail silently, and running the .exe returns these warnings – it seems like a few of the pvinfo/pvdata DLL’s don’t build correctly. The issue originally presented with base 7.0.4, and then I built fresh on 7.0.7 and saw the same issue. Has anyone ever had this issue on mingw? Transcription of one of the errors [ it opens a myriad of similar dialogs referencing missing entry points in pv****.dll files but I’ve just copied one of them since I don’t imagine the specific entry points are at issue] in case the image doesn’t carry through:

I don't use mingw (or windows) often, so I can't say for certain.
I suspect some kind of inconsistent/incomplete build.

Maybe your %PATH% includes older versions of pvlist and/or pvData.dll?

You could try running with a minimal %PATH% ?
