Hello all,
I have just met the following problem: I am cross-compiling boost 1.47 using
$ x86_64-w64-mingw32-g++ --version
x86_64-w64-mingw32-g++ (GCC) 4.5.4 20110822 (prerelease)
On Linux box with the following command:
./b2 -a toolset=gcc target-os=windows threading=multi threadapi=pthread runtime-link=static --layout=versioned --build-type=complete install
user-config.jam contains the following:
using gcc : mingw : x86_64-w64-mingw32-g++ ;
After that a linkage failed when building my project. I reproduced it with simple test program:
#include <boost/thread.hpp> #include <iostream>
using namespace std;
struct test { void operator()() { cout << "Called" << endl; } };
int main() { test test_obj; boost::thread thr(test_obj); thr.join(); }
The output looks like
$ x86_64-w64-mingw32-g++ -Wall test_boost.cpp -I ./3rdparty/boost/include/boost-1_47 -L ./3rdparty/boost/lib -lboost_thread-mgw-mt-s-1_47 -o test_boost.exe In file included from ./3rdparty/boost/include/boost-1_47/boost/thread/win32/thread_data.hpp:12:0, from ./3rdparty/boost/include/boost-1_47/boost/thread/thread.hpp:15, from ./3rdparty/boost/include/boost-1_47/boost/thread.hpp:13, from test_boost.cpp:2: ./3rdparty/boost/include/boost-1_47/boost/thread/win32/thread_heap_alloc.hpp:59:40: warning: inline function ‘void* boost::detail::allocate_raw_heap_memory(unsigned int)’ declared as dllimport: attribute ignored ./3rdparty/boost/include/boost-1_47/boost/thread/win32/thread_heap_alloc.hpp:69:39: warning: inline function ‘void boost::detail::free_raw_heap_memory(void*)’ declared as dllimport: attribute ignored /tmp/ccSmsBnO.o:test_boost.cpp:(.text+0xde): undefined reference to `__imp__ZN5boost6thread4joinEv' /tmp/ccSmsBnO.o:test_boost.cpp:(.text+0xfb): undefined reference to `__imp__ZN5boost6threadD1Ev' /tmp/ccSmsBnO.o:test_boost.cpp:(.text+0x1c3): undefined reference to `__imp__ZN5boost6threadD1Ev' /tmp/ccSmsBnO.o:test_boost.cpp:(.text$_ZN5boost6threadC1I4testEET_NS_10disable_ifINS_14is_convertibleIRS3_NS_6detail13thread_move_tIS3_EEEEPNS0_5dummyEE4typeE[boost::thread::thread<test>(test, boost::disable_if<boost::is_convertible<test&, boost::detail::thread_move_t<test> >, boost::thread::dummy*>::type)]+0xd5): undefined reference to `__imp__ZN5boost6thread12start_threadEv' collect2: ld returned 1 exit status
The same scenario works fine when linking with dynamic libboost_thread. Both static and dynamic builds work fine for Linux.
What could be the cause of the problem and where to look? Does it worse posting a defect in bug-tracker?
Thanks! -- Victor
