未定义对`boost::this_thread::interruption_point()‘的引用

Question

我正在尝试使用boost和rtmidi编译一个项目。然而，我一直收到以下编译错误。我使用的是linux、netbeans 7.2、boost 1.50.0和rtmidi 2.1.0。

g++ -D__LINUX_ALSA__ -lasound -lpthread 
-I/usr/local/boost_1_50_0 
-L/usr/local/boost_1_50_0/lib -L/usr/local/lib -L/usr/lib 
-lboost_system    
-o dist/Debug/GNU-Linux-x86/realtimebeatgenerationthesis build/Debug/GNU-Linux-x86/State.o build/Debug/GNU-Linux-x86/RawNote.o build/Debug/GNU-Linux-x86/MarkovEngineConsumer.o build/Debug/GNU-Linux-x86/Calibrator.o build/Debug/GNU-Linux-x86/main.o build/Debug/GNU-Linux-x86/MidiHandlerProducer.o build/Debug/GNU-Linux-x86/LetterPattern.o build/Debug/GNU-Linux-x86/Letter.o build/Debug/GNU-Linux-x86/Meter.o build/Debug/GNU-Linux-x86/VOMC.o build/Debug/GNU-Linux-x86/Metronome.o  

我得到的错误消息有两个部分：

undefined reference to `boost::this_thread::interruption_point()'

和

undefined reference to `RtMidiOut::RtMidiOut(RtMidi::Api, std::string)'
collect2: error: ld returned 1 exit status
make[2]: *** [dist/Debug/GNU-Linux-x86/realtimebeatgenerationthesis] Error 1
make[2]: Leaving directory `dir/NetBeansProjects/RealTimeBeat'
make[1]: *** [.build-conf] Error 2
make[1]: Leaving directory `dir/NetBeansProjects/RealTimeBeat'
make: *** [.build-impl] Error 2

编辑-1:嘿@matomatician1975，即使添加了我得到的那一个：

undefined reference to `boost::this_thread::interruption_point()'
build/Debug/GNU-Linux-x86/MarkovEngineConsumer.o: In function     `__static_initialization_and_destruction_0':
/usr/local/boost_1_50_0/boost/system/error_code.hpp:214: undefined reference to `boost::system::generic_category()'
/usr/local/boost_1_50_0/boost/system/error_code.hpp:215: undefined reference to  `boost::system::generic_category()'
/usr/local/boost_1_50_0/boost/system/error_code.hpp:216: undefined reference to `boost::system::system_category()'

最后，我通过链接器添加->添加库、boost_thread、boost_system和rtmidi，最终使其正常工作。在命令行中会出现类似以下内容的结果：

g++ -Wall -D__LINUX_ALSA__ -I/usr/local -L/usr/local/lib/ -L/alsa/ -lasound -lpthread -o          build/Debug/GNU-Linux-x86/Calibrator.o ..../main.o ...../MidiHandlerProducer.o ...../LetterPattern.o ..../Letter.o ..../Meter.o ..../VOMC.o ..../Metronome.o -L/usr/local/lib -lboost_thread -lboost_system -lrtmidi 

Answer 1

您似乎没有链接到boost线程库。尝试在构建路径中添加-lboost_thread。

Answer 2

我也有同样的问题，尽管我确信我链接的东西是正确的。如果你进一步阅读你的错误输出，你可能会发现架构不匹配：
