打印字符串并返回的简单程序。我可以通过输入 ./a.out 直接执行它。但是当我在gdb中运行它时，会出现上述错误。我尝试使用 -g 标志编译代码，而不使用它。两次都给出了相同的结果。任何人都可以帮我解决这个问题??

I wrote a simple program which prints a string and returns. I was able to execute it directly, by typing "./a.out". But when I run it in gdb the error mentioned above happens. I tried compiling the code using the "-g" flag and without using it. Both time it gave the same result. Can anyone help me with this issue??

推荐答案

那个消息，

That message,

warning: no loadable sections found in added symbol-file system-supplied

是一个警告，它不会阻止GCC运行 a.out ;至少，它不应该。

is a warning that does not prevent GCC from running a.out; at least, it should not.

这是说有一个动态加载的对象被 a.out 使用缺少符号。没有关于a.out本身。

It is saying that there's a dynamically loaded object used by a.out that is missing symbols. Nothing about a.out itself.

您可以尝试将a.out构建为静态可执行文件;像这样：

You can try to build a.out as a static executable; like this:

gcc -static a.c

显然，需要添加任何其他编译器参数。

Obviously, add any other compiler arguments needed.

作为一个静态可执行文件，您不会从GCC获得警告。这些符号可能仍然丢失，但不应该影响程序的执行。

As a static executable, you won't get that warning from GCC. Those symbols may still be missing, but it should not affect execution of the program.
