[Boost Error] /opt/ros/melodic/lib/libroscpp.so: undefined reference to boost::system::system_category()' /opt/ros/melodic/lib/librosconsole.so: undefined reference to boost::re_detail_106501::cpp_regex_traits_implementation::transform_primary[abi:cxx11]~

[Goal]

• ROS package와 연관되어 있는 boost version을 확인하고 올바르게 해결할 수 있다.

---

[Cause]

• ROS distribution 마다 최소 package 버전 또는 fit한 version들이 존재하는데 이들이 local에 설치되어 있는 version에 맞춰 설치를 꼭 진행해주어야 한다.
• 모든 ros-melodic-XXX 페키지들을 매번 git clone하여 install 하기 어렵다면 boost version을 맞춰서 설치를 해주어야 한다.
  • 즉, `sudo apt-get install ros-melodic-rosconsole`을 설치하면 boost 1.65.1 dependency에 맞게 local에 설치가 됨
  • 본인이 boost version이 1.69.0이라면 boost 버전을 바꾸던지 rosconsole git clone을 하여 1.69.0을 install 할지 선택해야함
  • 그런데 git clone을 할꺼면 엄청 많은 package들을 clone해야하는데 너무 귀찮고 많아서 boost version을 변경하기로 선택함

---

[Process]

• [Step 1] `dpkg -l | grep libboost-dev` 을 통해 local에 설치된 boost version check
  • 저자의 경우 다음과 같이 결과 나타남

(base) sj@sj:~$ dpkg -l libboost-dev

ii  libboost-dev:amd64      1.65.1.0ubuntu1  amd64            Boost C++ Libraries development files (default version)

• [Step 2] 저자의 경우 ros melodic 을 설치하였는데 1.65.1 버전의 boost를 설치 진행하여야 함
