[HELP] Compiling under Visual Studio 2015

[psyHoTik]

Hello! Could you please help me with compiling OXC under MVS Community 2015? I've followed this walkthrough, but I'm getting following errors/ warnings:

Code: [Select]

I also get many "Unknown compiler version - please run the configure tests and report the results" messages.

Any suggestions? Please have mercy as this is the first time I compile something for Windows

The walkthrough on UFOpedia is for vs2010 and vs2013.

For vs2015, you will need new precompiled dependencies.
You can make your own (good luck with that)... or use mine: https://openxcom.org/forum/index.php/topic,3937.msg56803.html#msg56803

PS: There are no official precompiled dependencies for vs2015 yet... as far as I know.

[psyHoTik]

Thank you very much I'll try that.

[psyHoTik]

OK, I've used your vs2015 deps and YAML_CPP_DLL definition and I got a successful build (again big thanks for help) but the game is not starting. I get the following error:

I haven't tried the #include <algorithm> thing as there were no errors at building...

[harre]

the includes needed for the new yaml-cpp dependancy is pulled from my fork.

you get same problem as me, it's seem to be some issues when running in debug-mode. I havn't figured out what is going wrong. Try a release-build instead.

[psyHoTik]

Building a release failed  I got a lot of warnings about possible loss of data due to conversion and 2 errors:

Do you link all required files from yaml lib? This error expecting to have static variable `YAML::detail::node_data::empty_scalar` of type `std::string` defined somewhere.

Do you link all required files from yaml lib? This error expecting to have static variable `YAML::detail::node_data::empty_scalar` of type `std::string` defined somewhere.

The truth is... I don't know  I just followed the walkthrough from Ufopaedia, only difference is that I used Meridian dependencies for vs2015 and I add "YAML_CPP_DLL" preprocessor definition (also suggested by Meridian). I haven't modified the code yet. The effect is:
1. In Debug mode building is successful (no errors, no warnings) but the game crashes on start
2. In Release mode building fails - 2 errors (described above) and about 180 warnings, mostly "conversion - possible loss of data"

That's all I know for now. Like I said in different thread, I'm not a real programmer - I just wanted to experiment a little with AI code (I have some C++ knowledge) and hoped that build can be made with some tutorial, without going into too much details. It seems it's not that easy

How can I check if this whole YAML-thing is linked correctly?

[Yankes]

Then you probably use wrong yaml version. Meridian use newer one than in normal OXC. This is way you don't get this errors with `<algorithms>`.
Old one include lot of different headers (like from boost library). New one only that they need. In consequence some files in OXC depend on headers included by yaml and after upgrade its break build of OXC.

[Meridian]

He uses my precompiled version of YAML... which is probably incorrectly compiled... I can't make debug version work on my machine. But the release version works fine for me. I told you, use at own risk 

Also.... he is not getting the <algorithm> errors, because the includes were added into latest nightlies just a week ago: https://github.com/SupSuper/OpenXcom/commit/0b91559b9a61fcefa906558d939c10092ab2f624

... just for explanation. Unfortunately I cannot help you with your actual issue, because I know too little about this myself. But I have installed VirtualBox today and will install probably Ubuntu over the weekend... maybe compilation under Linux won't be as much pain as it is under vs2015.

EDIT: btw. did you add YAML_CPP_DLL also for Release mode? Maybe you added it only for Debug build.... that might be the cause...

[harre]

I have build release-mode succesfully with Meridan's dependancies, I think as he says that you probably forgot to add the YAML_CPP_DLL preprocessor directive.

Try checkout this fork, it should be just building with no modifications after downloading Meridan's depencancies.

Exactly, that was the case I didn't know that this is separate for debug and release. The code compiled successfully (although with 3991 warnings ) and the game runs.

Try checkout this fork, it should be just building with no modifications after downloading Meridan's depencancies.

Thanks, I'll have that in mind in case some other issues come up.

Again big thanks for all of you, guys.
