我正在尝试使用 boost 和 rtmidi 编译一个项目。但是我不断收到以下编译错误。我正在使用 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

我收到的错误消息的两部分是：

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

EDIT-1：嘿@mathematician1975，即使加上我得到的那个：

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，我终于通过添加链接器->添加库 boost_thread boost_system 和 rtmidi 使其工作。在命令行中导致类似于以下内容：

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

您似乎没有链接到 boost 线程库。尝试添加-lboost_thread您的构建路径。

我有同样的问题，尽管我确定我正确地链接了一些东西。如果您进一步阅读错误输出，您可能会发现架构不匹配：

ld: warning: ignoring file /.../boost/lib/libboost_system.dylib, file was built for x86_64 which is not the architecture being linked (i386)
ld: warning: ignoring file /.../boost/lib/libboost_filesystem.dylib, file was built for x86_64 which is not the architecture being linked (i386):
