error while loading shared libraries: liblopack.so.0 on RasPi

[okyeron]

Device: Raspberry Pi 4 w/ 5.4.79-v7l+ (desktop)

With a fresh install - when I try to run joyosc, I get a shared libraries error for liblopack.so.0. However, if I run it from the binary in joyosc/src/joyosc it works.

liblopack.so.0 exists at /usr/local/lib/

Is this a build error somewhere?

pi@raspberrypi:~/joyosc $ joyosc -e

I assume joyosc and lsjs are installed to /usr/local/bin?

[okyeron]

Yes indeed:

pi@raspberrypi:~/joyosc $ ls -la /usr/local/bin

drwxr-xr-x  3 root root     4096 Aug 18 12:16 .

Did you run configure with --prefix=/usr/local?

[danomatika]

It might be related to this SO post where ldconfig is not being run for some reason.

[danomatika]

Same here.

It seems you need to run sudo ldconfig on your system to add the installed helper libraries in /usr/local/lib to the lib cache. If that works, I can add the info to the readme. I don't think this step should be done automatically by make install as not all systems may require it.

sudo ldconfig

Yes - That worked!

Now as expected:

pi@raspberrypi:~/joyosc/src/joyosc $ joyosc -e
listening port:  7770
listening multicast group: none
listening addr:  /joyosc
sending ip:      127.0.0.1
sending port:    8880
sending address for notifications: /joyosc/notifications
sending address for devices:       /joyosc/devices
print events?:   yes
joysticks only?: no
sleep us:        10000
device addresses: 0

Ok thanks. I updated the readme.

Note: This should no monger be a problem with joyosc 0.5.0+ as the tinyobject and lopack helper libraries are no longer used.
