On FreeBSD the test fails to link without `-lpthread`: ``` os command: gmake clean LD_EXTRAS='-L/tank/emaste/src/llvm/build-nodebug/bin/../lib/python2.7/site-packages/../.. -llldb' EXE='test_listener_event_description' CFLAGS_EXTRAS='-std=c++11 -stdlib=libc++ -I/tank/emaste/src/llvm/tools/lldb/test/../include' CXX_SOURCES='driver.cpp listener_test.cpp test_listener_event_description.cpp'; gmake ARCH=amd64 CC="/usr/bin/clang" LD_EXTRAS='-L/tank/emaste/src/llvm/build-nodebug/bin/../lib/python2.7/site-packages/../.. -llldb' EXE='test_listener_event_description' CFLAGS_EXTRAS='-std=c++11 -stdlib=libc++ -I/tank/emaste/src/llvm/tools/lldb/test/../include' CXX_SOURCES='driver.cpp listener_test.cpp test_listener_event_description.cpp' with pid: 92054 stdout: rm -f "test_listener_event_description" driver.o listener_test.o test_listener_event_description.o driver.d listener_test.d test_listener_event_description.d rm -f -r rm -rf *.o *.d *.dSYM /usr/bin/clang++ -std=c++11 -g -O0 -m64 -std=c++11 -stdlib=libc++ -I/tank/emaste/src/llvm/tools/lldb/test/../include -I/tank/emaste/src/llvm/tools/lldb/test/make/../../include -c -o driver.o driver.cpp /usr/bin/clang++ -std=c++11 -g -O0 -m64 -std=c++11 -stdlib=libc++ -I/tank/emaste/src/llvm/tools/lldb/test/../include -I/tank/emaste/src/llvm/tools/lldb/test/make/../../include -c -o listener_test.o listener_test.cpp /usr/bin/clang++ -std=c++11 -g -O0 -m64 -std=c++11 -stdlib=libc++ -I/tank/emaste/src/llvm/tools/lldb/test/../include -I/tank/emaste/src/llvm/tools/lldb/test/make/../../include -c -o test_listener_event_description.o test_listener_event_description.cpp /usr/bin/clang++ driver.o listener_test.o test_listener_event_description.o -g -O0 -m64 -std=c++11 -stdlib=libc++ -I/tank/emaste/src/llvm/tools/lldb/test/../include -I/tank/emaste/src/llvm/tools/lldb/test/make/../../include -L/tank/emaste/src/llvm/build-nodebug/bin/../lib/python2.7/site-packages/../.. -llldb -o "test_listener_event_description"

My quick Google search suggests linking requirements for std::thread are quite system-dependent; AFAICT some Linuxes also need -lpthread -- perhaps a combination of the specific libc, libpthread, and libc++. http://reviews.llvm.org/D5838 _______________________________________________ lldb-commits mailing list [email protected] http://lists.cs.uiuc.edu/mailman/listinfo/lldb-commits
