Problem machen: Keine Regel, um Ziel /usr/lib/x86_64-linux-gnu/libpcl_common.so zu machen


8

Ich folge diesem Tutorial, um eines der von PCL (Point Cloud Library) bereitgestellten Beispiele auszuführen: https://www.youtube.com/watch?v=CXK95Hi4M7I

Beim Ausführen des Befehls make ( https://youtu.be/CXK95Hi4M7I?t=243 ) wird jedoch die folgende Ausgabe angezeigt:

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

Könnte mir jemand sagen, was das Problem ist und wie ich es lösen kann?

Vielen Dank

Hast du libproj-devinstalliert? Installieren Sie es und versuchen Sie es erneut.

@ Seth ja es ist bereits installiert. Ich habe meinen Beitrag mit dem Makefile

Der Fehler:

make [2]: *** Keine Regel, um das Ziel '/usr/lib/x86_64-linux-gnu/libpcl_common.so' zu erstellen, das von 'range_image_visualization' benötigt wird. Halt.

bedeutet, dass make die Datei /usr/lib/x86_64-linux-gnu/libpcl_common.so, die zum Beenden der Kompilierung benötigt wird, nicht finden kann .

Überprüfen Sie zunächst, ob die Datei vorhanden ist:

$ 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, also müssen wir es installieren. Der einfachste Weg, um herauszufinden, was das Paket bietet, libpcl_common.soist die Verwendung eines Tools namens apt-file. Installieren und einrichten Sie es:

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

Wenn das erledigt ist, können Sie ausführen:

$ 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

Und los geht's! Installieren libpcl-devSie und Sie sollten golden sein.

Es ist auch erwähnenswert, dass sich in Ihrem Quellverzeichnis normalerweise eine README-Datei mit einer Liste der Abhängigkeiten befinden sollte, die Sie installieren müssen, um einige dieser Vermutungen zu beseitigen und Zeit zu sparen.


Übrigens suche ich normalerweise Pakete mit apt-cache. Mit anderen Worten, ich habe hier "sudo apt-cache pkgnames libpcl" ausprobiert, was mehr Optionen bietet. Aber ich habe überhaupt keine Ahnung, welche ich installieren soll. Ist es besser, immer Ihre alternative dh apt-Datei zu verwenden? Wie unterscheiden sie sich?

@trilolil apt-cache searchsucht nur den Paketnamen und die Kurzbeschreibung. apt-file searchschaut in die Pakete, um zu sehen, welche die gesuchte Datei enthält.
