Okay I've fixed this bug but now I get a new bug which is this

I have no means to actually test this on linux.

Looks like you need the steamapi dll. It's in the project, might need to be manually copied to your build directory.

[sodomon2]

and compiled the mono-build version

in which directory is the steam_api dll located?

[Blecki]

It's just in the project directory.

If you're building the mono csproj - it compiles (maybe) but does not work. All of the shaders need to be converted, for starters; and I'm sure plenty more. For Linux, try the FNA version.

[sodomon2]

@Blecki the FNA version is the one I'm running

the binary it creates is DwarfCorpFNA.mono

[Blecki]

Okay, that should work then if you have the dependencies right.

[sodomon2]

What are the units? I just installed mono

[Blecki]

Everything you need - including FNA - is in the repository.

Copy the contents of FNA_Libs\libs\ and FNA_Libs\mono\ to your output directory.

[sodomon2]

mmm e past all the librearias that were in the

FNA_Libs/libs64/ and FNA_Libs/mono/ but I still get the steam_api error

[Blecki]

Did you copy the steam dll too?

[sodomon2]

yes,copy steam_api.dll and libsteam_api.so

[Blecki]

I don't know what this libsteam.so stuff is about.

[sodomon2]

@Blecki I still get the error, I think it might be because in linux the .dll extension doesn't work, it works is .so maybe that's why I don't run the game

[Blecki]

Dlls work, maybe not on every flavor. Really don't know. You might be able to cut out the dependency entirely; steam is optional.

[sodomon2]

@Blecki Okay, remove the steam libraries.

both steam_api.dll and libsteam_api.so

but I still get the error

[Blecki]

I meant remove all references from the code.

[sodomon2]

Okay, but where are these references in the code? 😅

[Blecki]

That will take me a bit longer to tell you.

[sodomon2]

ok,:c

[Blecki]

Okay; so get rid of everything in gamestates/modmanagement/steam/ then you should be able to comment out everything that breaks.

[sodomon2]

I don't understand, you want me to delete the directory gamestates/modmanagement/steam/ ?

[Blecki]

Yes, and fix up the compilation errors that result. It's not required for the game to run, just to use the mod discovery and installation features.

[sodomon2]

@Blecki ok I don't get the steam_api error anymore,but now I get another error,the error says it can't find xna_draw.xnb

[Blecki]

Did you copy the content from the windows build?

[sodomon2]

no,copy the content of DwarfCorp/DwarfCorpContent

[sodomon2]

@Blecki

ok I already copied the xna_draw.xnb from the window content,but when I run I get another error,and this time it's with MojoShader

[sodomon2]

ok myself and compiled the libmojoshader.so

but when I run it I get an error which is this

EXT_swap_control_tear unsupported. Fall back to standard VSync.
