Question

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

make -C Source/Tools/NiViewer
make[1]: Entering directory `/home/ejohns/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/ejohns/Data/Libraries/OpenNI2/Source/Tools/NiViewer'
make: *** [Source/Tools/NiViewer] Error 2

关于如何解决这个问题的任何想法？

Answer 1

你必须添加指令＆＃34; -lpthread＆＃34;到你的编译器，它就解决了。

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

Answer 2

您需要将pthread库添加到target_link_libraries中。您可以编辑CMakeLists.txt文件，如下所示。这个解决方案适合我。

    target_link_libraries(ExcutableFileName ${Existed_LIBRARY})
    -->
    target_link_libraries(ExcutableFileName ${Existed_LIBRARY} pthread)

make期间出错：添加符号时出错：命令行中缺少DSO
