这似乎与此问题相同:
boost_log example with sinks fails to compile
但是,添加-lpthread
似乎没有任何效果。这是我用来编译的完整命令行:
/ usr / bin / c ++ -g
拓扑/测试/ CMakeFiles / topologyTest.dir / main.cpp.o topology / test / CMakeFiles / topologyTest.dir / configTests.cpp.o -o topology / test / topologyTest -rdynamic -lboost_log -lboost_log_setup -lboost_thread -lboost_program_options -lboost_serialization -lboost_unit_test_framework -lboost_filesystem -lboost_system -lboost_date_time -lboost_regex -lboost_chrono -lboost_atomic -lpthread topology / lib / libtopologyLib.a topology / testLib / libtopologyTestLib.a utility / testLib / libutilityTestLib.a topology / lib / libtopologyLib.a -lpthread -lboost_log -lboost_log_setup -lboost_thread -lboost_program_options -lboost_serialization -lboost_unit_test_framework -lboost_filesystem -lboost_system -lboost_date_time -lboost_regex -lboost_chrono -lboost_atomic -lpthread expression / lib / libexpressionLib.a utility / lib / libutilityLib.a
我尝试使用定制的1.60版本的boost;
/ usr / bin / g ++ -g
拓扑/测试/ CMakeFiles / topologyTest.dir / activatorTests.cpp.o 拓扑/测试/ CMakeFiles / topologyTest.dir / main.cpp.o 拓扑/测试/ CMakeFiles / topologyTest.dir / neuronTests.cpp.o 拓扑/测试/ CMakeFiles / topologyTest.dir / speciesTests.cpp.o topology / test / CMakeFiles / topologyTest.dir / synapseTests.cpp.o -o topology / test / topologyTest -rdynamic -lpthread /usr/local/lib/libboost_log.so /usr/local/lib/libboost_log_setup.so /usr/local/lib/libboost_serialization.so /usr/local/lib/libboost_system.so /usr/local/lib/libboost_thread.so /usr/local/lib/libboost_unit_test_framework.so /usr/local/lib/libboost_date_time.so /usr/local/lib/libboost_filesystem.so /usr/local/lib/libboost_regex.so /usr/local/lib/libboost_chrono.so /usr/local/lib/libboost_atomic.so -lpthread topology / lib / libtopologyLib.a topology / testLib / libtopologyTestLib.a utility / testLib / libutilityTestLib.a topology / lib / libtopologyLib.a -lpthread /usr/local/lib/libboost_log.so /usr/local/lib/libboost_log_setup.so /usr/local/lib/libboost_serialization.so /usr/local/lib/libboost_system.so /usr/local/lib/libboost_thread.so /usr/local/lib/libboost_unit_test_framework.so /usr/local/lib/libboost_date_time.so /usr/local/lib/libboost_filesystem.so /usr/local/lib/libboost_regex.so /usr/local/lib/libboost_chrono.so /usr/local/lib/libboost_atomic.so -lpthread expression / lib / libexpressionLib.a utility / lib / libutilityLib.a -Wl,-rpath,/ usr / local / lib
在这两种情况下,我得到的错误是:
/ usr / bin / ld:/usr/local/lib/libboost_log.so:未定义的引用 符号'_ZN5boost6detail12get_tss_dataEPKv' /usr/local/lib/libboost_thread.so:错误添加符号:DSO丢失 从命令行collect2:错误:ld返回1退出状态
我尝试将-DBOOST_LOG_DYN_LINK
附加到命令而没有效果。
我正在使用ubuntu 16.04
。
我有点失落。任何想法我缺少什么/如何诊断?
答案 0 :(得分:1)
尝试与if ($_POST) {
// user has submitted the form
// get the form field values
$userEmail = $_POST['userEmail'];
// more fields...
// validate the values
// prepare the sql statements
// execute insert statement here
}
,
和将-lboost_thread
更改为-DBOOST_LOG_DYN_LINK
。
