Could not successfully build lr-reicast - Dremcast emu - reicast port for libretro (/home/mac/RetroPie-Setup/tmp/build/lr-reicast/reicast_libretro.so not found).

@vermope What's the actual error you get during the compilation ? The lr-reicast works for me under Ubuntu x86_64.

@mitu these are the last lines of the log:

Makefile:734: recipe for target 'core/libretro/libretro.o' failed

These are not helpful to diagnose the issue, are just generic 'something failed to compile' messages. Get the full log file and upload it to pastebin.com. The setup script will create log files for each operation in $HOME/RetroPie-Setup/logs, find the latest one (they are timestamped) and put its contents on pastebin.com.

@mitu Ok tnx! I look into it when I'm @home

The error is

There's a compiler error that's not solvable by RetroPie - either update your gcc compiler or use more recent distro. What's the gcc version (g++ --version) ? I tested on Ubuntu 18.04 and 16.04 (+updates) and I don't get this error. Your OS seems to be based on Ubuntu 16.04.01 (while the latest patch version is for 15.04 LTS is 16.04.05), but using a very recent kernel (?), so I'm not sure which version is included.

Woohoow, thank you @mitu !! I've upgraded the compiler and managed to install "lr-reicast".

This can be compiled under raspberry pi 3b+?

mitu

@saitoh00 No, it's available right now as an experimental package just for the PC.

saitoh00

ok mitu, very thanks, im hope al least we can test in Raspberry in the future, any plans to include it?

mitu

@saitoh00 It depends on the development of the core, if it supports the Pi hardware.

nipeters

@mitu I'm hoping it does make it onto Raspberry pi 3b or 4!
