đặt vấn đề: Không có quy tắc nào để tạo mục tiêu /usr/lib/x86_64-linux-gnu/libpcl_common.so

Tôi đang theo hướng dẫn này để chạy một trong những ví dụ được cung cấp bởi PCL (thư viện đám mây điểm): https://www.youtube.com/watch?v=CXK95Hi4M7I

Nhưng khi thực hiện lệnh make ( https://youtu.be/CXK95Hi4M7I?t=243 ) tôi nhận được kết quả đầu ra sau:

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

Ai đó có thể cho tôi biết vấn đề là gì và làm thế nào tôi có thể giải quyết nó?

Cảm ơn bạn

Lỗi:

make [2]: *** Không có quy tắc nào để tạo mục tiêu '/usr/lib/x86_64-linux-gnu/libpcl_common.so', cần thiết bởi 'Range_image_visualization'. Dừng lại.

có nghĩa là làm cho không thể tìm thấy tệp /usr/lib/x86_64-linux-gnu/libpcl_common.somà nó cần để hoàn thành quá trình biên dịch.

Trước tiên hãy kiểm tra xem tệp có tồn tại không:

$ 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, vì vậy chúng tôi cần phải cài đặt nó. Cách dễ nhất để tìm ra gói nào cung cấp libpcl_common.solà sử dụng một công cụ được gọi là apt-file. Cài đặt và thiết lập nó:

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

Khi xong, bạn có thể chạy:

$ 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

Và ở đó bạn đi! Cài đặt libpcl-devvà bạn nên vàng.

Cũng đáng lưu ý rằng thông thường , trong thư mục nguồn của bạn, cần có một tệp README với danh sách các phụ thuộc bạn sẽ cần cài đặt, điều này sẽ giúp loại bỏ một số suy đoán này và tiết kiệm thời gian.
