I believe that if a warning is generated, then it is normal for the compiler to state that warnings are being treated as errors on the first occurrence if the -Werror option is set. > > Furhtermore I have noticed that the following test examples are missing ( I > am looking for them in src/tests as described in > https://svn.apache.org/repos/asf/qpid/trunk/qpid/cpp/examples/README.txt) : > > # ./direct_producer > # ./listener > > # ./server > # ./client > These examples are located in the cpp/examples directory, not cpp/src/tests. I cannot find in the README file above (at least in the latest version on trunk) where the tests directory is mentioned. The examples are built as part of "make check"; it is possible that the error you are experiencing below may stop the build before it gets to the examples. > > Making check in managementgen > make[1]: Entering directory > `/home/volare/mom_brokers/qpidc-0.6/managementgen' > make[1]: Nothing to be done for `check'. > make[1]: Leaving directory > `/home/volare/mom_brokers/qpidc-0.6/managementgen' > Making check in etc > make[1]: Entering directory `/home/volare/mom_brokers/qpidc-0.6/etc' > make[1]: Nothing to be done for `check'. > make[1]: Leaving directory `/home/volare/mom_brokers/qpidc-0.6/etc' > Making check in src > make[1]: Entering directory `/home/volare/mom_brokers/qpidc-0.6/src' > Making check in . > make[2]: Entering directory `/home/volare/mom_brokers/qpidc-0.6/src' > make[2]: Leaving directory `/home/volare/mom_brokers/qpidc-0.6/src' > Making check in tests > make[2]: Entering directory `/home/volare/mom_brokers/qpidc-0.6/src/tests' > if test -d /home/volare/mom_brokers/qpidc-0.6/src/tests/../../../python -a > -d /home/volare/mom_brokers/qpidc-0.6/src/tests/../../../specs; \ > then make -C > /home/volare/mom_brokers/qpidc-0.6/src/tests/../../../python install > PREFIX=/home/volare/mom_brokers/qpidc-0.6/src/tests/python > PYTHON_LIB=/home/volare/mom_brokers/qpidc-0.6/src/tests/python > EXEC_PREFIX=/home/volare/mom_brokers/qpidc-0.6/src/tests/python/commands > AMQP_SPEC_DIR=/home/volare/mom_brokers/qpidc-0.6/src/tests/../../../specs; \ > else echo "WARNING: python client not built, missing one of > /home/volare/mom_brokers/qpidc-0.6/src/tests/../../../python > /home/volare/mom_brokers/qpidc-0.6/src/tests/../../../specs"; fi > WARNING: python client not built, missing one of > /home/volare/mom_brokers/qpidc-0.6/src/tests/../../../python > /home/volare/mom_brokers/qpidc-0.6/src/tests/../../../specs > make libshlibtest.la libdlclose_noop.la unit_test perftest txtest > latencytest echotest client_test topic_listener topic_publisher publish > consume header_test failover_soak declare_queues replaying_sender > resuming_receiver txshift txjob PollerTest DispatcherTest qpid_ping datagen > qrsh_server qrsh_run qrsh qpid_stream > make[3]: Entering directory `/home/volare/mom_brokers/qpidc-0.6/src/tests' > make[3]: `libshlibtest.la' is up to date. > make[3]: `libdlclose_noop.la' is up to date. > make[3]: `unit_test' is up to date. > make[3]: `perftest' is up to date. > make[3]: `txtest' is up to date. > make[3]: `latencytest' is up to date. > make[3]: `echotest' is up to date. > make[3]: `client_test' is up to date. > make[3]: `topic_listener' is up to date. > make[3]: `topic_publisher' is up to date. > make[3]: `publish' is up to date. > make[3]: `consume' is up to date. > make[3]: `header_test' is up to date. > make[3]: `failover_soak' is up to date. > make[3]: `declare_queues' is up to date. > make[3]: `replaying_sender' is up to date. > make[3]: `resuming_receiver' is up to date. > make[3]: `txshift' is up to date. > make[3]: `txjob' is up to date. > make[3]: `PollerTest' is up to date. > make[3]: `DispatcherTest' is up to date. > make[3]: `qpid_ping' is up to date. > make[3]: `datagen' is up to date. > depbase=`echo qrsh_server.o | sed 's|[^/]*$|.deps/&|;s|\.o$||'`;\ > g++ -DHAVE_CONFIG_H -I. -I../../src -I../../include -I../../include > -I../../src -I../../src -Werror -pedantic -Wall -Wextra -Wno-shadow > -Wpointer-arith -Wcast-qual -Wcast-align -Wno-long-long > -Wvolatile-register-var -Winvalid-pch -Wno-system-headers > -Woverloaded-virtual -DBOOST_TEST_DYN_LINK -g -O2 -MT qrsh_server.o -MD -MP > -MF $depbase.Tpo -c -o qrsh_server.o qrsh_server.cpp &&\ > mv -f $depbase.Tpo $depbase.Po > cc1plus: warnings being treated as errors > qrsh_server.cpp: In member function ‘void > qpid::tests::QrshServer::getNames()’: > qrsh_server.cpp:489: error: ignoring return value of ‘int fscanf(FILE*, > const char*, ...)’, declared with attribute warn_unused_result > qrsh_server.cpp: In member function ‘void > qpid::tests::QrshServer::execute(const qpid::client::Message&)’: > qrsh_server.cpp:590: error: ignoring return value of ‘int system(const > char*)’, declared with attribute warn_unused_result > make[3]: *** [qrsh_server.o] Error 1 > make[3]: Leaving directory `/home/volare/mom_brokers/qpidc-0.6/src/tests' > make[2]: *** [check-am] Error 2 > make[2]: Leaving directory `/home/volare/mom_brokers/qpidc-0.6/src/tests' > make[1]: *** [check-recursive] Error 1 > make[1]: Leaving directory `/home/volare/mom_brokers/qpidc-0.6/src' > make: *** [check-recursive] Error 1 > It might be helpful if you could tell us which distribution you are using, and what the compiler version is. It looks on the face of it that your compiler is tuning on a "warn_unused_result" warning check - possibly as part of the -Wall flag which is set during configure, and this is picking up these two lines in the qrsh_server.cpp file - which do indeed ignore the result of two system calls, and should be fixed at some point. I would see if you can override that particular warning flag, or turn off the -Werror flag - that should get you a compile you can use. Open a JIRA for this issue (https://issues.apache.org/jira/browse/QPID) so it does not get forgotten.
