CMakeFiles/robot_arm_ui.dir/src/CCtrlDashBoard.cpp.o: In function CCtrlDashBoard::CCtrlDashBoard(QWidget*, CCtrlDashBoard::StyleType)': CCtrlDashBoard.cpp:(.text+0x4e): undefined reference tovtable for CCtrlDashBoard' CCtrlDashBoard.cpp:(.text+0x5c): undefined reference to `vtable for CCtrlDashBoard' collect2: error: ld returned 1 exit status

cpp .h文件导入后会报这样错误，重新编译也解决不了。QT小白 不吝赐教

cmakelist添加如下两句： set(CMAKE_INCLUDE_CURRENT_DIR ON)

添加c++11的支持

set(CMAKE_CXX_FLAGS "-std=c++11 ${CMAKE_CXX_FLAGS}")

可以对比我的cmakelist，里面的每一行都不可缺少

ok 解决了 感谢 还有个问题就算QT 订阅图像话题，qt处理图像有大约2s的延时，这个有办法改进么？

您好，请问您是怎么解决的呢？我也是遇到你说的这个问题，在cmakelist.txt添加up主说的那两行也没有效果，还是一样的报错
