I am trying to include boost library to xcode, and xcode is complaining about include.
I am a mac user, and the library is under
/usr/local/boost_1_62_0
Under Build Setting, I added the path for Header Search Paths and User Header Search Paths.
In .cpp, I tried to use
#include <boost/asio.hpp>
but it threw an error saying fix the to "quote". Once I did that, it's complaing about the libary files themselves have to fix to "quote", as attached picture shows.
Any suggestions??
Add /usr/local/boost_1_62_0 to System Header Search Paths instead of User Header Search Paths. Then you can write #include <boost/asio.hpp> without any problems.
#include <filename> is for including system library headers while #include "filename" is for user-defined headers.
All of the instances of #include <boost/filename.hpp> in the Boost header files expect boost/filename.hpp to be in the system header search path, which isn't the case when you just set User Header Search Paths to /usr/local/boost_1_62_0.
asio.hppin/usr/local/boost_1_62_0/boost/asio.hppor somewhere else, such as/usr/local/boost_1_62_0/include/boost/asio.hpp?
