Basic install failed - could not successfully build muplen64plus

RonReese

@ronreese anyway I finally managed to figure it out, changed the video setting in the config file and it didn't fix it, it's still the same. I'll try to get the log file this evening now I understand a bit more about what I'm doing.

mitu

OK, that's progress. Can you upload the retroarch.cfg file you modified on pastebin.com and provide the link, so we can check its contents ? Do the same for the log file for the compilation of the Mupen64plus emulator.

RonReese

@mitu Yes will aim to do so, sorry for the delay had a busy weekend

RonReese

@mitu here's the cfg file https://pastebin.com/Y07UZdjG

mitu

@ronreese This is the default file - you didn't modify the video_driver line as I indicated in a previous post. Of course it won't work.

RonReese

@mitu I did then I had to change it back, as I stated it didn't work and I couldn't use anything on the laptop when I tried to load a game, the whole screen went blurred

mitu

Can you try updating RetroArch now and see if it works ?

RonReese

@mitu is there a new version of Retroarch to update to? or do you mean modify the video driver again?

mitu

@ronreese I mean just do an update of the RetroArch package from the RetroPie-Setup script or just just to update all packages. I think there's a new build of RA that disables the wayland video driver, which has been causing problems for some people using Ubuntu 18.04.

RonReese

@mitu OK that sounds good, I'll give it a go when I'm home

RonReese

@ronreese thanks for all of your help

@buzz said in Basic install failed - could not successfully build muplen64plus:

mupen64 currently fails on 32bit installs - should work on 64bit Ubuntu.

64 bit breaks a lot of other things. Why is the 32 bit not working?

BuZz

@knightofdespair Because the build system tries to link against a 64bit library I think but I can't remember for sure. What are the lots of other things 64bit breaks - I am not aware of them ?

@buzz the biggest problem I ran across was PCSX2, I am using a ~$300 Intel NUC to try to do everything up to a PS2 including Sega Saturn which works pretty well except the busted SDL2 on 64-bit and busted mupen64plus on 32-bit. Had a few scraping and controller issues but even the Dreamcast seems to work pretty well. If I can get all of those to play nice it will be a finished project.

mitu

@buzz I think this can be fixed by adding

 if compareVersions "$__os_debian_ver" ge 9; then
	     isPlatform "x86" && params+=("-DUSE_SYSTEM_LIBS=On")
fi

to the GLideN64 plugin build stage.
This flag used to be global, but was changed in https://github.com/RetroPie/RetroPie-Setup/commit/336f1398c7040f39ae057338978a739ffe8a5a60.

@mitu looks good thanks. I'll try it.

knightofdespair

Tried it out, worked for me! You guys are the best!

BuZz

I actually just made the flag global again - but perhaps your fix is better. However I guess it's not an issue on newer OSs - built ok on my x86_64 machine also.

mitu

@buzz I was considering the reason it was introduced - it could fail compiling on 16.04 based distributions due to the old libpng12 present there.

BuZz

@mitu I made some comments here - https://github.com/RetroPie/RetroPie-Setup/commit/336f1398c7040f39ae057338978a739ffe8a5a60 - but I don't think I want to worry too much about the old LTS now 18.04 is out.
