Question

我为项目图形创建一个cmakelist.txt。我使用库irrlicht。我遇到“ cmake”后遇到了问题，我确实使我出错了

cmakelist.txt

我想要一个可执行文件，但是有这个错误

Answer 1

您的编译器说您缺少符号XConvertSelection。我相信编译器已经为您提供了答案：

/usr/lib/x86_64-linux-gnu/libX11.so.6: error adding symbols: DSO manquant dans la ligne de commande

搜索错误消息very similar question has already been asked。将X11添加到CMakeLists.txt中的库列表中可以解决您的问题：

target_link_libraries(toto ${X11_LIBRARIES})

我使用irrlicht创建cmakelist时出错
