Failed to load dynamic library 'libserialport.so'

[eximius313]

I'm trying to use flutter_libserialport library.
I've followed the guidelines of Libserialport and built the library.
I clearly have a file /usr/local/lib/libserialport.so
Unfortunately, when I run sudo flutter-pi my_apps_flutter_assets I see red screen with message:

Failed to load dynamic library 'libserialport.so': 'libserialport.so': cannot open shared object file: No such file or directory

How to force flutter-pi to see the libserialport.so

Kind regards,

/usr/local/lib/ might not be in the default library search path.
try putting it in /usr/lib or launching flutter-pi with LD_LIBRARY_PATH=/usr/local/lib flutter-pi ...

Thanks!

# cd /usr/lib/
# ln -s /usr/local/lib/libserialport.so .

did the job!

I don't have libdart_vlc_plugin.so at there folder, but when I create flutter build -d linux it create this libdart_vlc_plugin.so

do i need to copy paste, or just ln -s

[ERROR:flutter/lib/ui/ui_dart_state.cc(209)] Unhandled Exception: Invalid argument(s): Failed to load dynamic library '/usr/local/bin/lib/libdart_vlc_plugin.so': /usr/local/bin/lib/libdart_vlc_plugin.so: cannot open shared object file: No such file or directory

@trapeye that's a different issue

dart_vlc will not work with flutter-pi without modification. You can't just copy the dart_vlcs plugin .so that was built for the linux desktop embedder, since linux desktop embedder and flutter-pi have different interfaces.

If you want to make dart_vlc working with flutter-pi you need to write some custom C code (in the flutter-pi source tree) to integrate it with flutter-pi's APIs
