Compile Errors RPI2 #1

Closed KMFDManic closed 2 years ago

KMFDManic commented 2 years ago

Thanks for opening up the issues here. I have gotten it to work successfully on one platform I utilize. But, on rpi2, it generates this error when attempting to run it:

[ERROR] Failed to open libretro core: "/etc/libretro/core/superbroswar_libretro.so" [ERROR] Error(s): /usr/lib/libstdc++.so.6: version `GLIBCXX_3.4.21' not found (required by /etc/libretro/core/superbroswar_libretro.so)

Is this similar to the Vita Static Link issue, or something else entirely? This "variant" of the jump n bump gameplay definitely reigns supreme. Very impressed by the sheer number of maps. I wonder if, when I did my video, you seeing me referring to it as a Mario Battle game, inspired you:) Anyways, thanks so much in advance! I would love to have this working for retropie 2 as well!

It's linking against a newer version of libstdc++ than it's loading at runtime? Maybe you can set LD_LIBRARY_PATH to get it to use the new version at runtime.

It compiles and finds all symbols for me (on Linux), but I get the error: ERROR: Empty map directory!. I tried to follow the source code and put the maps from testmaps.zip in ~/.config/retroarch/saves/superbroswar/maps, but no luck (I'd assume that they would go in the system directory like xrick data files do, but that's not what the source code indicates). I suppose we should wait until there's a README indicating how to use it before worrying too much about it being compilable and/or usable.

@keithbowes I actually got the game working fine on "some platforms". At the tail end of my issue, I link to a demonstration of it running. What would be awesome, is if you use Discord, and are able to join the one I am at. We can go over a few things, and I will get you up and running with this masterpiece!

I am KMFDManic there, as well. You can just shoot me a pm once you join, and we can go from there!

/usr/lib/libstdc++.so.6: version `GLIBCXX_3.4.21' not found

this looks like a cross-compiling issue, the compiler you are using is linking with a libstdc++.so.6 version different than the one used when running the core. Maybe there is an issue with the toolchain you are using... I can't really help you with that

You need to create a smw.game empty file in the data folder, and load that file as a RetroArch content

I'll try it. If I get it to work, I'll try to send a PR for a README.
