Fixed in a bit nicer way, by using NS_UNUSED inside constructor as in LTE tests previously. changeset: 10220:fd5b94ebc43f tag: tip user: Vedran Miletić <rivanvx@gmail.com> date: Mon Oct 21 10:38:06 2013 +0200 summary: Bug 1779 - NS_UNUSED_GLOBAL not working in attribute test class declaration Sorry for this, well, it seemed to compile nicely. |
Observed on Fedora Core 19, 64bit system, gcc-4.8.1, after the clang patch merge: In file included from ./ns3/nstime.h:27:0, from ../src/core/test/attribute-test-suite.cc:36: ./ns3/unused.h:10:54: error: ‘unused’ attribute ignored [-Werror=attributes] # define NS_UNUSED_GLOBAL(x) x __attribute__((unused)) ^ ../src/core/test/attribute-test-suite.cc:228:8: note: in expansion of macro ‘NS_UNUSED_GLOBAL’ bool NS_UNUSED_GLOBAL (m_boolTest); ^ ./ns3/unused.h:10:54: error: ‘unused’ attribute ignored [-Werror=attributes] # define NS_UNUSED_GLOBAL(x) x __attribute__((unused)) ^ ../src/core/test/attribute-test-suite.cc:229:11: note: in expansion of macro ‘NS_UNUSED_GLOBAL’ int16_t NS_UNUSED_GLOBAL (m_int16); ^ ./ns3/unused.h:10:54: error: ‘unused’ attribute ignored [-Werror=attributes] # define NS_UNUSED_GLOBAL(x) x __attribute__((unused)) ^ ../src/core/test/attribute-test-suite.cc:230:11: note: in expansion of macro ‘NS_UNUSED_GLOBAL’ int16_t NS_UNUSED_GLOBAL (m_int16WithBounds); ^ ./ns3/unused.h:10:54: error: ‘unused’ attribute ignored [-Werror=attributes] # define NS_UNUSED_GLOBAL(x) x __attribute__((unused)) ^ ../src/core/test/attribute-test-suite.cc:232:11: note: in expansion of macro ‘NS_UNUSED_GLOBAL’ uint8_t NS_UNUSED_GLOBAL (m_uint8); ^ ./ns3/unused.h:10:54: error: ‘unused’ attribute ignored [-Werror=attributes] # define NS_UNUSED_GLOBAL(x) x __attribute__((unused)) ^ ../src/core/test/attribute-test-suite.cc:233:9: note: in expansion of macro ‘NS_UNUSED_GLOBAL’ float NS_UNUSED_GLOBAL (m_float); ^ ./ns3/unused.h:10:54: error: ‘unused’ attribute ignored [-Werror=attributes] # define NS_UNUSED_GLOBAL(x) x __attribute__((unused)) ^ ../src/core/test/attribute-test-suite.cc:234:15: note: in expansion of macro ‘NS_UNUSED_GLOBAL’ enum Test_e NS_UNUSED_GLOBAL (m_enum); ^ cc1plus: all warnings being treated as errors I found this on the web, describing possible gcc-4.8.1 problem: http://readlist.com/lists/gcc.gnu.org/gcc-help/6/31119.html However, I also found problems on gcc-4.6.3: lback-test-suite.cc.3.o [1401/2177] cxx: src/core/test/command-line-test-suite.cc -> build/src/core/test/command-line-test-suite.cc.3.o ../src/core/test/attribute-test-suite.cc:228:8: error: ‘unused’ attribute ignored [-Werror=attributes] ../src/core/test/attribute-test-suite.cc:229:11: error: ‘unused’ attribute ignored [-Werror=attributes] ../src/core/test/attribute-test-suite.cc:230:11: error: ‘unused’ attribute ignored [-Werror=attributes] ../src/core/test/attribute-test-suite.cc:232:11: error: ‘unused’ attribute ignored [-Werror=attributes] ../src/core/test/attribute-test-suite.cc:233:9: error: ‘unused’ attribute ignored [-Werror=attributes] ../src/core/test/attribute-test-suite.cc:234:15: error: ‘unused’ attribute ignored [-Werror=attributes] so perhaps we should go back to Vedran's original suggested patch for attribute-test-suite.cc?
