boost + home-brew + macOS Sierra

Question

Ich versuche Boost in meinem C++ Projekt in MacOS Sierra zu verwenden. Ich habe installiert Boost-Home-Gebräu mit, etwa so:

Gebräu boost installieren

Meine CMakeLists.txt Datei sieht aus wie cmake_minimum_required (VERSION 3.8) Projekt (sr)

set(CMAKE_CXX_STANDARD 14) 

set(Boost_USE_STATIC_LIBS  OFF) # only find static libs 
set(Boost_USE_MULTITHREADED  ON) 
set(Boost_USE_STATIC_RUNTIME  OFF) 
find_package(Boost 1.64.0 COMPONENTS system log log_setup thread date_time filesystem regex chrono atomic REQUIRED) 

include_directories(src) 
include_directories(lib/easylogging++) 
include_directories(${Boost_INCLUDE_DIRS}) 

add_subdirectory(src) 
add_subdirectory(sr_tests) 

set(SOURCE_FILES main.cpp lib/easylogging++/easylogging++.cc) 

add_executable(sr_out ${SOURCE_FILES}) 
target_link_libraries(sr_out ${Boost_LIBRARIES} sr) 

Meine main.cpp ist einfach #include

int main() { 
    BOOST_LOG_TRIVIAL(info) << "hi"; 
    return 1; 
} 

In der Aufbauphase, die binäre mit Verbindung herstellen kann

Ich würde wirklich jede Hilfe bei der Einrichtung dieser Einrichtung zu schätzen wissen.

Answer 1

Das Problem war, dass die Boost Logging-Bibliothek dynamisch verknüpft werden musste. Ich reparierte meine CMakeLists.txt Datei diese Zeile hinzufügen:

add_definitions(-DBOOST_LOG_DYN_LINK=1) 

Dies das Problem behoben
