Lib과 Share, include를 build안에 생성하고 시스템 안에 있는 library 특징 및 경로, 합치기 등을 해보기

|

특정 LIB에 생성이 안되는 문제

add_library를 이용하여서 특정 function에대한 라이브러리를 생성을 해야되고

install 함수를 이용하여서 해당 project 환경 library에 넣어줘야 한다.

보통 실행 파일은 bin에다 넣고, library 파일은 lib에다 넣는다.

install function중에 share folder에 해당 package folder 및 file들을 보존할 수 있다.

root library(system library)와 local library(user library), project library, ros library등 os에 여러 환경들이 존재한다.

하지만 공통적으로 존재한 폴더들이 있다.

  • bin(실행파일)
  • lib(library)
  • include(library header 파일 및 개발 환경(기능)을 구성하는 header 파일)
  • shared(library package folder)
  • etc

이들은 즉 각 환경에서 가지고 있는 library들이 다르고 header 환경이 다르다. 그렇기 때문에 개발환경에 맞춰서 설치경로도 확인해야되고, 만약 library나 header를 못찾는다고 한다면, 현재 환경에 library가 깔려있는지, 다른 개발환경이면서 library가 깔려있는줄 착각하고 계속 불러오려고 하는지 확인을 해야된다.

만약 환경이 다른 곳에서 개발을 하고 있었으면, export 커맨드나 sh 파일을 실행하여서 환경변수를 맞춰주고 이를

env를 통해 확인한다.

만약 library들을 다 링킹해서 사용하고 싶다면,

export  LD_LIBRARY_PATH=${LD_LIBRARY_PATH}:/home/hosting_users/test/module/okname
export  LD_LIBRARY_PATH=${LD_LIBRARY_PATH}:/opt/ros/noetic/lib/
export  LD_LIBRARY_PATH=${LD_LIBRARY_PATH}:/usr/lib

및 bashrc 파일에

LD_LIBRARY_PATH=${LD_LIBRARY_PATH}:/home/hosting_users/test/module/okname
LD_LIBRARY_PATH=${LD_LIBRARY_PATH}:/opt/ros/noetic/lib/
LD_LIBRARY_PATH=${LD_LIBRARY_PATH}:/usr/lib

를 추가하고 source, 환경을 먹여주면 된다. 즉 글로벌하게 링킹을 걸어준다면 library 문제 없이 어디 어디서든 사용할 수 있다.
