Dear all,

can you please recompile tier1 for VS2015? (or tell me how to do it?)

https://github.com/alliedmodders/hl2sdk/commits/sdk2013
There was a commit from psychonic "Recompile Windows tier1 with VS2010.".

Probably that's the reason I get LNK2001 (unresovled external symbol) for __vsnprintf.

Thanks!

Edit: Steps to do it yourselves:

1. run createallprojects.bat in root folder
2. compile tier1\tier1.vcxproj
3. resolve errors

Edit 2: Recent hl2sdk-css gives me a bunch of errors when I include it. Doesn't seem to work well.

You do indeed get errors due to VS 2015's libraries being ABI-incompatible with previous versions. For that same reason, we're not going to ship libs for VS 2015 in the repository at this time - it would break compatibility with all older VS versions, which some people are still using.

You can either tell VS 2015 to use an older VS's toolset (this is what I do, telling it to use 2013). Or, you can just open the existing project file in /tier1 directory and compile. It may ask you to upgrade the project, which is fine. You will probably also have to recompile mathlib if you use it.

Is this going to be a problem when I use interfaces directly from the engine then? For now, everything seems to work. But maybe there are cornercases...

No. It's only the CRT that's incompatible due to some shuffling around of functions, which causes the linking errors you saw.

Okay, thanks. Shall I use hl2sdk-css or sdk2013 for current CS:S? I think -css because sdk2013 is probably for mods, isn't it?

Edit: If I compare sdk2013 to css, it seems much more complete than css only (e. g. materialsystem folder is missing, vstdlib too). Do I have to merge both of them to get a complete SDK?

[psychonic]

Some interfaces in sdk2013 are slightly newer than what is actually in CS:S. What's in hl2sdk-css should be plenty for plugins and is what Metamod:Source and Sourcemod both use for CS:S.

VS2015 "unresolved external symbol" errors related to the printf and scanf family of functions can be easily fixed by adding the legacy_stdio_definitions.lib to the linker.

I had the exact same error regarding tier1 with VS2015, and that fixed it

Hi Merudo,

thanks for posting. You saved me from installing Visual Studio 2013 :-)
