Hello, I have a warning when linking with the thread library. /usr/lib/gcc/i686-pc-cygwin/3.4.4/../../../../i686-pc-cygwin/bin/ld: warning: auto-importing has been activated without --enable-auto-import specified on the command line. When I set <library>/boost/thread//boost_thread/<link>static; instead of <library>/boost/thread//boost_thread; this works without warnings. What I need to do to link dynamically without warnings? Best regards Vicente ================== Command $ bjam The jamfile contains using testing ; if ! $(BOOST_ROOT) { BOOST_ROOT = [ modules.peek : BOOST_ROOT ] ; } project : : requirements <include>$(BOOST_ROOT) <include>../../.. <threading>multi <target-os>cygwin <threadapi>pthread <variant>debug <library>/boost/test//boost_unit_test_framework/<link>static <threading>multi <library>/boost/thread//boost_thread; Link warning: gcc.compile.c++ ..\..\..\bin.v2\libs\sync\test\include_concurrent_component.test\gcc-3.4.4\debug\target-os-cygwin\threadapi-pthread\threading-multi\include_concurrent_component.o **passed** ..\..\..\bin.v2\libs\sync\test\include_concurrent_component.test\gcc-3.4.4\debug\target-os-cygwin\threadapi-pthread\threading-multi\include_concurrent_component.test gcc.compile.c++ ..\..\..\bin.v2\libs\sync\test\static_thread_group_test.test\gcc-3.4.4\debug\target-os-cygwin\threadapi-pthread\threading-multi\static_thread_group_test.o gcc.link ..\..\..\bin.v2\libs\sync\test\static_thread_group_test.test\gcc-3.4.4\debug\target-os-cygwin\threadapi-pthread\threading-multi\static_thread_group_test.exe /usr/lib/gcc/i686-pc-cygwin/3.4.4/../../../../i686-pc-cygwin/bin/ld: warning: auto-importing has been activated without --enable-auto-import specified on the command line.
