LUA error: attempt to call global 'SetFogOfWarEasingSteps' (a nil value)

[etm]

I successfully extracted from setup_warcraft_ii_2.02v4(28734).exe which i downloaded from GOG.

When starting, the following error occurs. I have Fedora 40, lua 5.4.6

[string "/home/xxx/.stratagus/data.Wargus/scripts/stratagus.lua"]:204: attempt to call global 'SetFogOfWarEasingSteps' (a nil value) stack traceback: [string "/home/xxx/.stratagus/data.Wargus/scripts/stratagus.lua"]:204: in main chunk

Which version of stratagus ?

[etm]

Stratagus v3.3.2, Copyright (c) 1998-2020 by The Stratagus Project written by Lutz Sammer, Fabrice Rossi, Vladi Shabanski, Patrice Fortier, Jon Gabrielson, Andreas Arens, Nehal Mistry, Jimmy Salmon, Pali Rohar, cybermind and others. https://github.com/Wargus/stratagus Compile options ZLIB BZ2LIB VORBIS THEORA LINUX

then version that comes with fedora 40

Very strange, this method was added about 2 years ago. Do you have this line? https://github.com/Wargus/stratagus/blob/9a24853bd68d5e8fc97fec66e1a8cb4a543f999e/src/map/script_map.cpp#L1187

Just cheсked: this commit was merged after 3.3.2 release. So, you should use the same versions for both wargus and stratagus. 3.3.2 is latest stable. In your case, it looks like you're using the master for wargus and 3.3.2 for stratagus.

[etm]

You are right. Sadly i am not successful in compiling stratagus HEAD, i currently fail in editloop.cpp because guichan version seems different on fedora (and im am not sure what i need, vendored_guichan() cmake function is missing from my cmake and i am not sure how to get it).

I had some success with the 3.3.2 version, but there is a consistent crash when clicking on victory in level 4 horde (ToD). I can provide the savegame 1 second before victory in a different issue, but as i said its from an old version.

Make sure you have (git) submodule updated, i.e stratagus\third-party should not be empty, and should also contains guichan directory.

[etm]

@Jarod42: yes i missed the submodule. With submodule guichan errors go away. It compiles till end. But then during linking:

/usr/bin/ld: libstrataguslib.a(interface.cpp.o): in function `HandleCommandKey(int)': /home/mangler/Projects//stratagus/src/ui/interface.cpp:533:(.text+0x22f1): undefined reference to `lua_getglobal'.

I assume the problem is that I have no lua 5.1 (although if have compat-lua-* for fedora which contains 5.1 things. Manually linking to -llua-5.4 (against better judgement) of course produces a thing which immediatly segfaults. hmmm.

[Jarod42]

Try to set BUILD_VENDORED_LUA option to ON (CMake) to use provided version instead of system one...

[etm]

Thanks, that was it. It works together with wargus appimage. I will try to compile wargus next.
