Godot Engine – Multi-platform 2D and 3D game engine https://godotengine.org https://git.neuromancer.sk/godot.git/atom/drivers/builtin_openssl2?h=2.0-stable 2015-10-30T02:03:05Z 2015-10-30T02:03:05Z ZuBsPaCe 2015-10-29T13:31:48Z urn:sha1:b051914032aeb8112d22159d4009304f96a76ad8 The original, uncommited fix simply changed compiler flag /MT to /MD. This would link the C runtime dynamically instead of statically. This is bad, because some users would have to install the c runtime before starting the editor. You can find alot of info about this error, which can happen after upgrading to VS 2015, and there are workarounds. But I realized, that the only place, where iob_func is used, is in e_os.h of the openssl library. The latest version already contains a workaround. I simply updated the part in e_os.h.
