gcc 4.6.2 warns about inline+dllimport functions

Reported by: anonymous Owned by: viboes
Milestone: Boost 1.52.0 Component: thread
Version: Boost 1.50.0 Severity: Problem
Keywords: Cc:


In boost/thread/future.hpp, the functions make_error_code() and make_error_condition() are declared as "inline BOOST_THREAD_DECL". In MinGW GCC 4.6.2, this results in the functions declared as both inline and as dllimport, which causes GCC to emit warnings. This bug is similar to ticket #4315.

Test program:

#include <boost/thread.hpp>
int main()
    return 0;

Compiled via:

g++ -o test.exe test.cpp -IC:/boost/include/boost-1_50 -LC:/boost/lib -lboost_thread-mgw46-mt-1_50 -lboost_system-mg w46-mt-1_50


In file included from C:/boost/include/boost-1_50/boost/thread.hpp:24:0,

from test.cpp:1:

C:/boost/include/boost-1_50/boost/thread/future.hpp:103:5: warning: inline function 'boost::system::error_code boost::system::make_error_code(boost::future_errc)' declared as dllimport: attribute ignored [-Wattributes]
C:/boost/include/boost-1_50/boost/thread/future.hpp:112:5: warning: inline function 'boost::system::error_condition boost::system::make_error_condition(boost::future_errc)' declared as dllimport: attribute ignored [-Wattributes]
