As writing (so far) a fairly simple C ++ application (in fact, I just started porting our application with Qt and replacing it mainly with boost), I met a "general" error as follows:
(trimmed path) \ libboost_system.a (error_code.o): duplicate section .rdata $ _ZTSN5boost12noncopyable_11noncopyableE [__ ZTSN5boost12noncopyable_11noncopyableE] has different sizes
(trimmed path) \ libboost_filesystem.a (codecvt_error_category.o): duplicated section .rdata $ _ZTSN5boost12noncopyable_11noncopyableE [__ ZTSN5boost12noncopyable_11noncopyableE] has different sizes
I obviously use library systems and file systems, and everything went smoothly so far when the asio header is enabled
#include <boost/asio.hpp>
due to this single line of code: return boost::asio::ip::host_name();
As I understood from the boosts documentation, asio is just a header library, and so I did not include another boost library, but libboost_system and libboost_filesystem started to cause these problems.
I am working on Win 7 using MinGW. I created all the accelerating libs in one shot, issuing the following two commands:
bootstrap mingw
b2 toolset=gcc
I used the same MinGW kit for him, as now, to create my application. And of course, I use these pre-built libraries to communicate with my application.
When I remove ASIO include, my build works again.
Please comment if I missed some important part of my configuration for the sake of simplicity.
