Good idea. I didn't know where to look for the log. I had packed up my things but it is a good thing I decided to unpack because I forgot my powersupply.

That error doesn't mean that the binary is 'corrupted', it's just that it's crashing due to other circumstances.

Efriim

@mitu
But does not the log file line 405 mean that elf32.cc is corrupt, and thus the executable binary is too?

No, that's a compilation warning - not an error - for the following line from the source code.

Efriim

Reicast source is still not working in retropie packages.

And here is safe shutdown script for retroflag cases and more, https://github.com/crcerror/retroflag-picase
Install safeshutdown:
wget -O - "https://raw.githubusercontent.com/crcerror/retroflag-picase/master/install.sh" | sudo bash

And some extra scriptmodule packages
Exult - Ultima VII
wget -O ~/RetroPie-Setup/scriptmodules/ports/exult.sh - "https://raw.githubusercontent.com/amigagamer/ExultRetropie/master/exult.sh"

Extra scripts

I'll give it a shot later to see how it works - does the binary work ? Is there any specific game you tried ?

Efriim

@mitu
The binary works fine. I hear that the reicast source was updated is why I wanted to build the latest.

mitu

OK, so when installing from source, I get the same crash, so something must have been changed upstream. I'll try to get a bisect working.

mitu

Seems like an upstream issue, which is solved, but not yet merged - https://github.com/RetroPie/RetroPie-Setup/issues/2700 (leading to the a bug report on the Reicast repo - https://github.com/reicast/reicast-emulator/issues/1537).

Bisecting the issue points to an older commit (a808a8f3).

@mitu
Yeah it looks like I had problems installing the source a few months ago too.

I had a couple questions. In my fstab

UUID=1A92-F7C1   /home/pi/RetroPie/memorycard   vfat   defaults,noatime,users,rw,uid=pi,gid=pi   0   0

I thought this would mount on availability, do you know what options are added, for automount and so that it wont hang a startup process during boot for 180 seconds, when the usb is unplugged?

My other question, I don't know probably couldn't answer, on my last retropie installation, I had a startup time of around 15 seconds. I think i have done everything that I did on my last installation but I can still only get 18 seconds. Any ideas?

Automount is handled by the usbautomount service. If you don't have the disk permanently attached, then it's best to use the usbautomount service.

Startup times can be diagnosed with systemd-analyze - look into it to determine where the system spends it's time.

Efriim

The disk I plan on leaving attached. I'll look into options for mount; is option "nofail" supposed to mean that it will give up trying to mount if it is non-available?

systemd-analyze blame
the top four are nmbd.service 10.8s and hciuart.service 6.4s
then raspi-config.service 1.3s and smbd.service 1s

one is the net bios name server i was pretty sure I dont use that so i disabled it with
sudo systemctl stop nmbd
sudo systemctl disable nmbd

I do use bluetooth, It seems like it is unusually slow. Reading dmesg:
uart-pl011 3f201000.serial: no DMA platform data
brcmfmac: power management disabled
and brcmfmac: brcmf_c_preinit_dcmds; look like firmware warnings

raspi-config is probably nominal, though I don't know what it is calling or doing at startup.

I use samba smbd.service.
