How to build icq in win7 MSVC2015?

Question

Programming

As you know, mail.ru opened the source of the new ICQ. I just need to fix something in the client so that ICQ can be used normally. Now it has the same miserable interface as telegram, whatsapp and others who switched to the same framework.
I collected a boost for the 2015 studio, the rest seems to have been accepted by the project ... But it does not compile. Then I supposedly somewhere; didn’t put it, then) didn’t close it ... Now, in general, it’s beauty - it pretends that it can’t assemble under the seven and requires the SDK of the eight. I'm sure I'm doing something wrong.
Attention, the question is: How to build icq in win7 on MSVC-2015?
PS No, not necrophilia. Almost all alternative IMs are either not widely used or are authorized through a phone number. QIP generally threw the skates away ...

Answer 1

On windows 10, without a file, it's impossible to assemble. Uses two SDKs windows 7.1 and windows 8.1. Random errors come out, then replace ctype.h with cctype, then add define so that there is no error due to hash_map.
It seems to me that it will assemble normally only on visual studio 2013, tk. project files needed to be updated.
