libmupen64plus.so.2.0.0 not found

aron

Attempting to build RetroPie on a fresh Ubuntu 16.04 x64 install, following the instructions from https://retropie.org.uk/docs/RetroPie-Ubuntu-16.04-LTS-x86-Flavor/ exactly, I ran into this:

Could not successfully build mupen64plus - N64 emulator MUPEN64Plus
(mupen64plus-core/projects/unix/libmupen64plus.so.2.0.0 not found).

This is presented in the context of a dialog screen while running the Basic Install from the script. Any suggestions?

Oh, and after I hit enter to continue, it says:

Could not install package(s): flex bison nasm

and finally

Please see /home/aron/RetroPie-Setup/logs/rps_2017-04-17_212857.log.gz
for more in depth information regarding the errors.

I'll see what's there

Oh gosh, I should have looked first:

E: Could not get lock /var/lib/dpkg/lock

Et cetera. Seems like I just should rerun the setup script. The lock was probably taken temporarily by a background process checking for updates.

i also had this problem on ubuntu 16.04.2 32bit and lubuntu 17.04 64bit.

I installed the emu again from the setup script and both times it worked from there...not sure where the bug is...

BuZz

@allow No bug afaik - just apt-get failed to install the requisites as another process was using it.

but reproducable every time install retropie on ubunt?

Every time i tried it i got this error. No problem for me, but if it fails most of the time it looks like a bug to me .-)

It took me three tries. First two times failed with the same error, third time ran all the way through.

I also just ran into this on a fresh install of RetroPie on Ubuntu 16.04.2. I have run into it every time this year. Here are some relevant things I've seen from the logs. I'm hesitant to open a bug, though. Installing it manually from the packages menu in the setup script works fine. Anyone else seeing things like this?

Update, I looked more closely at nasm entries in the log. The step:

Installing dependencies for 'lr-mupen64plus' : N64 emu - Mupen64Plus + GLideN64 for libretro

comes after mupen64plus (non-libretro). The nasm package is installed as part of that step which is why it's missing earlier and fails.

That was fast. Fixed in: https://github.com/RetroPie/RetroPie-Setup/commit/a3880c22ff6e7d0fbfade633a9fb4574ff97cf1e

@aron i got same on compiling mupen64plus (standalone) on Tinker with missing error from specific build folder
/home/pi/RetroPie-Setup/tmp/build/mupen64plus/mupen64plus-core/projects/unix
I ve added a copy of the libmupen64plus.so.2.0.0 in the folder over winscp just asap scriptmodule created the build subfolder(s) and it compiled fine without an error.
Hope that work around helps
