CMakeLists at this point:
cmake_minimum_required(VERSION 2.8 FATAL_ERROR)
project(cloud_viewer)
find_package(PCL 1.2 REQUIRED)
include_directories(${PCL_INCLUDE_DIRS})
link_directories(${PCL_LIBRARY_DIRS})
add_definitions(${PCL_DEFINITIONS})
add_executable (random_sample_consensus random_sample_consensus.cpp)
target_link_libraries (random_sample_consensus ${PCL_LIBRARIES})The reason is that Windows can locate Boost multithreading but Ubuntu cannot, so you need to manually add two places in CmakeLists:
1. Find and add the linked library directory path;
2. Link the library to our project
After changing to:
cmake_minimum_required(VERSION 2.8 FATAL_ERROR)
project(cloud_viewer)
find_package(PCL REQUIRED)
include_directories(${PCL_INCLUDE_DIRS})
link_directories(${PCL_LIBRARY_DIRS})
add_definitions(${PCL_DEFINITIONS})
find_package(Boost REQUIRED COMPONENTS thread filesystem)
link_libraries(${Boost_LIBRARY_DIRS})
add_executable (random_sample_consensus random_sample_consensus.cpp)
target_link_libraries (random_sample_consensus ${PCL_LIBRARIES} ${Boost_LIBRARIES})Finally build successfully:
