gdb 和 makefile
大家好 我尝试调试一个已通过 makefile 安装的程序。 它有一个二进制文件 OpenDPI_demo.o 和一个 shell shellscript OpenDPI_demo。 当我 gdb OpenDPI_demo.o 时，我遇到了问题。我无法运行它。错误是：
Starting program: /home/lx/ntop/test/opendpi/src/examples/OpenDPI_demo/OpenDPI_demo.o
/bin/bash: /home/lx/ntop/test/opendpi/src/examples/OpenDPI_demo/OpenDPI_demo.o：can't execute the binary file.
请告诉我原因。实际上我可以通过./OpenDPI_demo运行该程序。 谢谢。
hello everyone
i try to debug a program, which have been installed by makefile.
it have a binary file of OpenDPI_demo.o and a shell shellscript OpenDPI_demo.
when i gdb OpenDPI_demo.o,i have a problem. i can't run it. the error is:
Starting program: /home/lx/ntop/test/opendpi/src/examples/OpenDPI_demo/OpenDPI_demo.o
/bin/bash: /home/lx/ntop/test/opendpi/src/examples/OpenDPI_demo/OpenDPI_demo.o：can't execute the binary file.
please tell me why. actually i can run the program by ./OpenDPI_demo.
thank you.

根据扩展名，该文件是目标文件。链接器（与其他目标文件一起）使用它来生成可执行文件。这是您想要运行/调试的真正的可执行文件。
Based on the extension, the file is an object file. It is used by the linker (alongside other object files) to produce an executable. It's the real executable the one you want to run/debug.
这是使用 libtool 的程序遇到困难的另一个例子。
正如您所说，文件
OpenDPI_demo与OpenDPI_demo.o实际上是一个 shell 脚本，它包装了实际编译文件的执行，可能在.libs/OpenDPI_demo 中。libtool 需要这个包装器来调整运行时库路径等，以便您可以透明地执行程序，就像它实际安装在您的系统上一样。
正确调试此应用程序的方法不是
在 shell 脚本上使用 libtool --mode=execute ，如下所示（这是一个示例）：
This is another example of difficulties encountered with programs using libtool.
the file
OpenDPI_demoalongsideOpenDPI_demo.ois actually, as you said, a shell script which wraps the execution of the real compiled file, probably in.libs/OpenDPI_demo.libtool needs this wrapper to adjust the runtime library paths and such so that you can execute the program transparently, as if it was actually installed on your system.
The way to correctly debug this application is not
but rather using
libtool --mode=executeon the shell script, like the following (it's an example):建议您在 makefile 中使用
，
如果它依赖于对象，请使其依赖于 OpenDPI_demo，例如
Suggest you use
instead
In your makefile if it depens on the object, make it depend on OpenDPI_demo, e.g.
