Ubuntu将可执行文件识别为共享库,并且不会通过单击来运行它

Question

我第一次在全新安装的lubuntu 17.04上遇到这个问题.我之前习惯使用Ubuntu而且以前没有这个问题.

我编译了我的qt应用程序,我可以通过发出"./"来通过命令行执行它.但是,我无法通过单击文件管理器(PCManFM,Nautilus ......)来执行它.两者都将其识别为共享库文件类型.

如何通过直接单击文件来运行它？

当我通过文件管理器双击可执行文件时会发生这种情况:

我通过在QT中的项目的.pro文件中添加以下行来修复此行为:

QMAKE_LFLAGS += -no-pie

之所以出现这种情况,是因为较新的ubuntu发行版设置了GCC默认链接标志-pie,它将e_type标记为二进制文件中的ET_DYN.因此,操作系统将识别为共享库.

要解决它,可能需要在编译器选项上添加-no-pie.
