Basic install failed - could not successfully build muplen64plus

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.

@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.
