无法解密nvlink错误

Question

我正在尝试用它来构建一个项目nvcc.我收到了nvlink error:我见过的最令人烦恼的消息.

这是链接声明:

nvcc    -rdc=true -arch=sm_21 -O3 -Xcompiler -fPIC -I"/usr/local/ACE_wrappers" -I"/usr/local/ACE_wrappers/TAO" -I"/usr/local/DDS" -I"/usr/include/Qt" -I"/usr/include/QtCore" -I"/usr/include/QtGui" -I"../../include" -I"../../include/DDS" -I"../../include/CoordinateTransforms" -I"../../include/DDS/IDLBrokerTemplates" -I"../../def/IDL" -I"../../def/CMD" -I"../../def/XSD" -I"../../src/NetAcquire" -I"/usr/local/ACE_wrappers/TAO/orbsvcs" -I"/usr/local/include/lct.7.5.4" -L"." -L"/usr/local/ACE_wrappers/lib" -L"/usr/local/DDS/lib" -L"/usr/lib64" -L"/usr/local/lib64" -L"../../def/IDL/lib" -L"../../def/XSD" -L"/usr/local/lib" .obj/../../src/Component.o .obj/../../src/COM.o .obj/../../src/DDS/EntityManager.o .obj/../../src/IDLBrokerTemplates/CommandManager.o .obj/../../src/IDLBrokerTemplates/OptionManager.o .obj/../../include/ApplicationProcessStateReporter_moc.o .obj/../../src/Application.o .obj/../../src/CoordinateTransforms/Site.o .obj/../../src/CoordinateTransforms/Geodesy.o .obj/../../src/CoordinateTransforms/Earth.o .obj/../../src/CoordinateTransforms/StateVector.o .obj/../../src/CoordinateTransforms/KeplerianImpact.o .obj/../../src/CoordinateTransforms/GeodeticPosition.o .obj/../../src/IDLBrokerTemplates/MeasurandSubscription.o .obj/../../src/NetAcquire/NetAcquire.o .obj/DataLossFlightTimeImpl.o .obj/DataLossFlightTime.o .obj/DftTable.o .obj/OptionListener.o .obj/PrimaryListener.o .obj/MissionTimeListener.o .obj/DeadMan.o .obj/main.o .obj/../../src/XML/spline.o .obj/../../src/XML/FpTable.o -l"naps-x86_64" -l"naio-x86_64" -l"nalct-x86_64" -l"curl" -l"TAO_Messaging" -l"TAO_Valuetype" -l"TAO_PI_Server" -l"TAO_PI" -l"TAO_CodecFactory" -l"TAO_CosNaming" -l"armadillo" -l"boost_filesystem" -l"boost_system" -l"xerces-c" -l"jarssXSD" -l"OpenDDS_Tcp" -l"JARSSRTv10" -l"QtNetwork" -l"fontconfig" -l"QtGui" -l"QtCore" -l"OpenDDS_Rtps_Udp" -l"OpenDDS_Rtps" -l"OpenDDS_Multicast" -l"OpenDDS_Udp" -l"OpenDDS_InfoRepoDiscovery" -l"OpenDDS_Dcps" -l"TAO_PortableServer" -l"TAO_AnyTypeCode" -l"TAO" -l"ACE"  -o "DFT"

而且我得到了

nvlink error   : Undefined reference to '_ZN5JARSS15KeplerianImpactC1ERKdS2_S2_S2_S2_S2_'
nvlink error   : Undefined reference to '_ZNK5JARSS15KeplerianImpact9getStatusEv'
nvlink error   : Undefined reference to '_ZNK5JARSS15KeplerianImpact13getImpactTimeEv'
nvlink error   : Undefined reference to '_ZNK5JARSS15KeplerianImpact11getPlhStateEv'
nvlink error   : Undefined reference to '_ZN5JARSS15KeplerianImpactD1Ev'
nvlink error   : Undefined reference to '_ZN5JARSS7Geodesy12EFG2GeodeticERKdS2_S2_PdS3_S3_'

我确定这些函数/文件包含在编译中.你可以从编译中看到KeplerianImpact.cpp并且Geodesy.cpp在那里.

有没有办法让链接输出更容易阅读,所以我可以调试这个？

Answer 1

使用c++filt以还原函数的名称.例如:

$ c ++ filt _ZN5JARSS15KeplerianImpactC1ERKdS2_S2_S2_S2_S2_ JARSS :: KeplerianImpact :: KeplerianImpact(double const&,double const&,double const&,double const&,double const&,double const&)
