c++ - make : error adding symbols: DSO missing from command line 时出错

Question

我正在尝试编译从 git 存储库(OpenNI2，https://github.com/occipital/OpenNI2)下载的一些代码。运行 make 后出现以下错误:

make -C Source/Tools/NiViewer
make[1]: Entering directory `/home/karnivaurus/Data/Libraries/OpenNI2/Source/Tools/NiViewer'
g++ -o ../../../Bin/x64-Release/NiViewer ./../../../Bin/Intermediate/x64-Release/NiViewer/Device.o ./../../../Bin/Intermediate/x64-Release/NiViewer/Draw.o ./../../../Bin/Intermediate/x64-Release/NiViewer/Keyboard.o ./../../../Bin/Intermediate/x64-Release/NiViewer/Menu.o ./../../../Bin/Intermediate/x64-Release/NiViewer/MouseInput.o ./../../../Bin/Intermediate/x64-Release/NiViewer/NiViewer.o ./../../../Bin/Intermediate/x64-Release/NiViewer/Capture.o -L../../../ThirdParty/PSCommon/XnLib/Bin/x64-Release -L../../../Bin/x64-Release -lglut -lGL -lOpenNI2 -lXnLib -Wl,-rpath ./

make[1]: Leaving directory `/home/karnivaurus/Data/Libraries/OpenNI2/Source/Tools/NiViewer'
make: *** [Source/Tools/NiViewer] Error 2

关于我应该如何解决这个问题有什么想法吗？

Answer 1

您必须将指令“-lpthread”添加到您的编译器，它已解决。

例如，如果您之前的代码是:g++ mycode.cpp -o myexecutable

现在你必须把g++ mycode.cpp -lpthread -o myexecutable
