crea problema: nessuna regola per rendere target /usr/lib/x86_64-linux-gnu/libpcl_common.so

8

Sto seguendo questo tutorial per eseguire uno degli esempi forniti da PCL (libreria di nuvole di punti): https://www.youtube.com/watch?v=CXK95Hi4M7I

Ma quando eseguo il comando make ( https://youtu.be/CXK95Hi4M7I?t=243 ) ottengo il seguente output:

yalishanda@yalishanda-thinkpad-x200:~/PCL/visualRangeExample/build$ make
make[2]: *** No rule to make target '/usr/lib/x86_64-linux-gnu/libpcl_common.so', needed by 'range_image_visualization'.  Stop.
CMakeFiles/Makefile2:67: recipe for target 'CMakeFiles/range_image_visualization.dir/all' failed
make[1]: *** [CMakeFiles/range_image_visualization.dir/all] Error 2
Makefile:83: recipe for target 'all' failed
make: *** [all] Error 2

Qualcuno potrebbe dirmi qual è il problema e come posso risolverlo?

Grazie

Hai libproj-devinstallato? Installalo e riprova.

@Seth sì, è già installato. Ho aggiornato il mio post con il Makefile

L'errore:

make [2]: *** Nessuna regola per rendere target '/usr/lib/x86_64-linux-gnu/libpcl_common.so', necessario per 'range_image_visualization'. Fermare.

significa che make non riesce a trovare il file /usr/lib/x86_64-linux-gnu/libpcl_common.sonecessario per completare la compilazione.

Prima controlla se il file esiste:

$ stat /usr/lib/x86_64-linux-gnu/libpcl_common.so  
stat: cannot stat '/usr/lib/x86_64-linux-gnu/libpcl_common.so': No such file or directory

Ok, quindi dobbiamo installarlo. Il modo più semplice per capire quale pacchetto fornisce libpcl_common.soè usare uno strumento chiamato apt-file. Installa e configura:

sudo apt-get install apt-file
apt-file update

Al termine puoi eseguire:

$ apt-file search /usr/lib/x86_64-linux-gnu/libpcl_common.so  
libpcl-common1.8: /usr/lib/x86_64-linux-gnu/libpcl_common.so.1.8
libpcl-common1.8: /usr/lib/x86_64-linux-gnu/libpcl_common.so.1.8.0
libpcl-dev: /usr/lib/x86_64-linux-gnu/libpcl_common.so

E il gioco è fatto! Installa libpcl-deve dovresti essere d'oro.

Vale anche la pena notare che di solito , all'interno della directory di origine, dovrebbe esserci un file README con un elenco delle dipendenze che è necessario installare, che dovrebbe aiutare a rimuovere alcune di queste ipotesi e risparmiare un po 'di tempo.

a proposito, di solito cerco pacchetti usando apt-cache. In altre parole qui ho provato "sudo apt-cache pkgnames libpcl", che offre molte più opzioni. Ma non ho idea di quale installare. È meglio usare sempre la tua alternativa cioè apt-file? In che modo differiscono?
— LandonZeKepitelOfGreytBritn,

@trilolil apt-cache searchcerca solo il nome del pacchetto e la breve descrizione. apt-file searchsta cercando all'interno dei pacchetti per vedere quale include il file cercato.
