I am approaching to this set of libraries cause I need to create a personal project for my university exam and I'd like to do something with networking features. I already got a book about this specific library but now i can't link this in my project (my book explains only how to link it on linux with GCC, but I'm uning CLion with MinGW on Windows 10). When I compile a simple empty project like this:
#include <boost/asio.h>
int main ( int argc, char ** argv ) {
return 0;
}
I get this impressive error:
CMakeFiles\Hello.dir/objects.a(main.cpp.obj): In function `_static_initialization_and_destruction_0':

Here is my CMakeLists.txt
cmake_minimum_required(VERSION 3.6)
project(Hello)
set(CMAKE_CXX_STANDARD 14)
set(SRC_FILES main.cpp)
include_directories(C:\\boost_1_63_0)
link_directories(C:\\boost_1_63_0)
find_package(BOOST 1.63.0 REQUIRED)
add_executable(Hello ${SRC_FILES})
How can I solve this? Thanks in advance!
EDIT
I updated my CMakeLists.txt as it follows:
cmake_minimum_required(VERSION 3.8.0)
project(Hello)
set(CMAKE_CXX_STANDARD 14)
set(SRC_FILES main.cpp)
set(BOOST_ROOT C:\\boost_1_63_0)
find_package(Boost 1.63.0 COMPONENTS system REQUIRED)
find_library(WS2_32_LIBRARY ws2_32)
link_directories(C:\\boost_1_63_0)
link_libraries(${BOOST_LIBRARIES})
add_executable(Hello ${SRC_FILES})
target_link_libraries(Hello ${WS2_32_LIBRARY} ${BOOST_LIBRARIES})
And now I don't get any error, anyway when I tell my program:
#include <boost/asio.hpp>
the boost gets red and the static analyzer tells me "Cannot find boost". Where's the problem now? Thanks!
