Another issue with python stuff.

Code:
/etc/init.d/pigpiod start
 * Starting pigpiod ...
/usr/bin/pigpiod: error while loading shared libraries: libpigpio.so: cannot open shared object file: No such file or directory
 * start-stop-daemon: failed to start `/usr/bin/pigpiod'
 * Failed to start pigpiod                                                                                                     [ !! ]
 * ERROR: pigpiod failed to start


The thing is, it's supposed to be fixed in version 69, we just got 68 today so it may be a while - so I tested a patch from here: https://github.com/joan2937/pigpio/issues/266

no joy, still the same error. Guess I'll have to wait for a version 69 and then[/code] see?

Ok so I don't know if this is really what you want to hear, but if you haven't actually tried downgrading to an earlier version that may be better than upgrading to the latest release since sometimes issues arise and they are not worked out for some time. But assuming you have tried it and there is still an issue with the shared libraries the fix is going to probably involve manually locating the file somewhere (hopefully it got installed somewhere in the fs) then from there you just need to use the path to it by setting the environment variable for LDPATH in /etc/env.d. Files in this directory are numbered for priority but I don't think it matters as long as you create a file (using package name, e.g. 10pigpio) and inside that file you will tell the linker where to look for it.

Thanks. Need to remember to run eix-update from time to time.

It has compiled, pigpiod starts without errors, python module loads. off to test stuff! :-)

Gosh...

python
Python 3.6.9 (default, Aug 6 2019, 18:42:28)
[GCC 8.3.0] on linux
Type "help", "copyright", "credits" or "license" for more information.
>>> import pigpio
>>> pi = pigpio.pi()
%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%
Can't connect to pigpio at localhost(8888)

Do you have permission to access the pigpio daemon?
Perhaps it was started with sudo pigpiod -nlocalhost
%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%

Changing default port in /etc/confd/pigpio to 8889 doesn't seem to make a difference:
Code:

Python 3.6.9 (default, Aug  6 2019, 18:42:28)
[GCC 8.3.0] on linux
Type "help", "copyright", "credits" or "license" for more information.
>>> import pigpio
>>> pi = pigpio.pi('soft', 8889)
%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%
Can't connect to pigpio at soft(8889)

Did you start the pigpio daemon? E.g. sudo pigpiod

Did you specify the correct Pi host/port in the environment
variables PIGPIO_ADDR/PIGPIO_PORT?
E.g. export PIGPIO_ADDR=soft, export PIGPIO_PORT=8888

Did you specify the correct Pi host/port in the
pigpio.pi() function? E.g. pigpio.pi('soft', 8888)
%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%


Could it be linked to my network setup like for this person?:

Is the pigpio daemon running? What port(s) is it listening on? Use ss -lnpt to see all listening TCP servers. If run as root, it will also show the process behind each listener.
