I am trying to use boost 1.47 on cygwin 1.7 cross-compiling to win32 with i686-w64-mingw32-g++ (4.5.3).

This program gives me an error:

#include int main() { boost::thread_specific_ptr<int> ts; return 0; }

$ i686-w64-mingw32-g++ -o mgw-release/obj/Tests/toto.o -c -O3 -DNDEBUG -Wall -Wextra -pipe -mthreads -I/cygdrive/d/Softs/1.7/mgw-release/boost/include -I. Tests/toto.cc In file included from

any help would be welcome.

Try to compile with -DBOOST_THREAD_USE_LIB=1
