Assuming that Blender developers still want to support Vista…
…the test build raises an error about K32EnumProcess being unavailable while the nightly does not.
I found this erudite discussion about the issue and how to solve it. From that discussion one finds that the fix boils down to #define-ing PSAPI_VERSION 1 and linking psapi.lib.
I investigated this strange behaviour of the fix appearing/disappearing in different builds so I downloaded 2.74 sources and investigated. The sources do not contain the #define. Inside the CMakeList.txt. psapi.lib is linked (lines 1173 and 1546) but the -DPSAPI_VERSION=1 is never stated.
The result is therefore that:
- if you want to support Vista, the define is missing (sources or CMakeLists.txt);
- if you don’t want to support Vista, the link library in CMakeLists.txt is redundant.
I leave the final decision to the powers to be.
