Visual Studio 2015 compilation issues

[oboroc]

I opened Unreal_2010.sln with Visual Studio 2015. tslabs, you mentioned you're using it. First time I opened it, VS2015 prompted me to upgrade project and solution. I let it. Then I tried to build solution, I got this error:

1>LIBCMTD.lib(swprintf.obj) : error LNK2001: unresolved external symbol __swprintf
1>bin\Debug\Unreal.exe : fatal error LNK1120: 1 unresolved externals
========== Rebuild All: 0 succeeded, 1 failed, 0 skipped ==========

There is a Stack Overflow discussion about unresolved external symbol sprintf and sscanf in Visual Studio 2015. The problem is that project contains *.lib files that were compiled using older versions of Visual C++. Those older versions expected linkable versions of standard C library functions, including swprintf(). Visual C++ 2015 is using inline versions for those functions, and so linker can't find linkable versions.

*.lib files in Unreal project:

zx-evo\pentevo\unreal\Unreal\lib\dinput.lib
zx-evo\pentevo\unreal\Unreal\lib\dxerr8.lib
zx-evo\pentevo\unreal\Unreal\ft8xx\ft8xxemu.lib

The quick and dirty fix is to add legacy_stdio_definitions.lib to project. This will restore old linkable standard C library functions.

Best fix is to replace *.lib with some stub code that has function declarations and load needed DLLs at run-time. Here is a good example on Stack Overflow: Dynamically load a function from a DLL.

Fixed by adding solution and project for VS2015 and removing dependencies on dinput&dxerr8. Please check if it works ok.

Thanks for looking into it! I tried to compile with Unreal_2015.sln. "Debug Unreal - Win32" target builds fine, "Release Unreal - Win32" fails to build. Compilation itself works fine, but something fails in post-build parts:

Actually, this bug exists in all solutions. You need to delete the unreal\bin\unreal.7z manually before building the Rrelease. I'll fix it later.

[oboroc]

@thims, so if I want to build release, I shouldn't build debug first?

[oboroc]

ok, I'll close this issue. Thanks, @thims
