AppVeyor CI - Windows builds

[Jammyjamjamman]

Creating a ticket here to keep track of building on appveyor.

Problems with package manager

Libs which are not available on vcpkg:

• google-breakpad (breakpad is available, so I download this)
• include (this looks like a custom dir full of headers for megaglest to link libs)
• lib (looks like another custom megaglest dir full of various libs)
• libircclient (this is a problem)
• lpng (using libpng instead)
• direct x sdk (is this necessary?)
• vlc (I'm downloading this using nuget instead, we'll see if that works)

So the package I think that is the biggest problem is libircclient

[Jammyjamjamman]

Some problems I found so far:

• RTCc checks (type coercion problem detection) were preventing builds succeeding - solved (switch it off)
• Some headers e.g. any sdl header does not link properly with vcpkg because e.g. SDL.h -> sdl2/SDL.h (unsolved)
• Cannot link libvlc from nuget package to project (unsolved, but the header file is there so I don't know what's wrong.)
• libircclient is only available on sourceforge (unsolved)

[Jammyjamjamman]

hardcoding the path to libvlc allows vlc-based project to build, so vlc nuget is a valid project.

Managed to build libglest (vs2019), but I had to copy some headers out of SDL2 directory in vcpkg folder and I had to manually specify lib directories.

[Jammyjamjamman]

Linked everything and glest_game appears to build, but the linker leaves me with 3300 + errors (mostly "unresolved external symbol").

[Jammyjamjamman]

Now using libglew from nuget, because version from vcpkg is too new.

Build gets so far then fails catastrophically at linking

I made a second attempt at building on windows with vcpkg, with no luck 👎 . I get these errors currently:

1>libglest.lib(miniupnpc.obj) : error LNK2019: unresolved external symbol __imp_ssdpDiscoverDevices referenced in function upnpDiscoverDevices

StopOnFirstBuildError: Build cancelled because project "glest_game" failed to build.
Build has been canceled.

I have no idea what I'm doing at this point. Some forum posts online would suggest additional libs need linking, but who knows what the right libs to link are or how you find out which need linking. There's no online help for these specific link errors, afaik.

Anyone else wants to give it a try with what I've done can look at this branch https://github.com/MegaGlest/megaglest-source/tree/vcpkg_build

It seems that there are many reasons for these so-called LNK2019 warnings. Whoever works on this next might get some hints at https://stackoverflow.com/questions/19886397/how-to-solve-the-error-lnk2019-unresolved-external-symbol-function

This was one of my favorite answers ;)

it turned out i was using .c files with .cpp files. renaming .c to .cpp solved my problem.

I've pushed some more changes to https://github.com/MegaGlest/megaglest-source/tree/vcpkg_build

Megaglest now builds, but fails to run. All that happens is the game starts, the loading spinner flickers, and I get this in console:

> .\megaglest

The game then ends. No other info is provided. This maybe because I'm building with /MT, not /MTd (multithreaded, without debug).

I ran it in verbose to get some more info, but nothing obviously suspicious:

Steps to reproduce what I've done so far:

1. Get Visual studio 2019 https://visualstudio.microsoft.com/downloads/ Install with the windows c++ development tools.
2. Pull this project https://github.com/MegaGlest/megaglest-source/tree/vcpkg_build
3. Get vcpkg: https://github.com/microsoft/vcpkg Follow the instructions to install. (You must use the ./vcpkg integrate install option too).
4. install packages with vcpkg: vcpkg install sdl2pp:x64-windows-static ftgl:x64-windows-static libjpeg-turbo:x64-windows-static curl:x64-windows-static openal-soft:x64-windows-static libvorbis:x64-windows-static lua:x64-windows-static miniupnpc:x64-windows-static glew:x64-windows-static xerces-c:x64-windows-static openssl:x64-windows-static
5. Add a new environment variable to windows: VCPKG_ROOT. Set this variable to the directory in which your git clone of vcpkg is located.
6. Get libircclient: https://sourceforge.net/projects/libircclient/files/libircclient/1.10/ Extract libircclient.lib and libircclient.dll to megaglest-source\source\windows_deps_2015\lib\.
7. Open the solution in megaglest-source/mk/windoze/vc2015. (I have actually upgraded it to a 2019 project.)
8. Build glest_game project. The final binary will be located in megaglest-source\mk\windoze\x64\Debug.

These steps will successfully build megaglest, but it will not run properly and there will be no errors. I tried copying and running it in the same directory as my standard megaglest installation and running it with --verbose, which produced the log I shared above.

I have been re-attempting this, with a lot more success (mainly thanks to @andy5995 ).
Decided to try and build using cmake: https://github.com/MegaGlest/megaglest-source/tree/windows-cmake-build-testing

This uses vcpkg+cmake+msbuild. I tested it using visual studio c++ tools + vscode. It's quite nice because you don't have to install the visual studio ide. You can compile it by running vcpkg+cmake+msbuild commands.

I had some problems with the function stackdumper(). But I think that's due to some incorrect macros in the code. (If debug is set, the code for stackdumper() is never generated. But stackdumper() is still called.)

My next plan is to make a new branch, with the cmake corrected properly, rather than just hacked. Hopefully can create debug+release build options, rather than just debug.
