gcc的输出(The output of gcc)

我在我的ubuntu操作系统上运行gcc。 我在c中编写了一个小程序并尝试编译它。 它的输出是像在Windows上一样的a.out。 如何让它发布Linux可执行文件？

I have gcc running on my ubuntu operating system. I wrote a small program in c and tried compiling it. It's output was an a.out like it would do on windows. How can I make it put out a Linux executable?

最满意答案

a.out 是可执行文件（假设您已经完成了完整的编译，而不仅仅是生成目标文件，但这是最可能的情况）。 要运行它，请使用（从shell）：

./a.out

如果你想给它一个不同的名字，只需重命名，或者更好：

gcc -o actualname myprog.c

获取一个名为actualname的可执行文件，然后运行（当然）：

./actualname

请参阅以下记录：

pax> cat testprog.c #include <stdio.h> int main (void) { printf("Hi.\n\n"); return 0; } pax> gcc testprog.c ; ./a.out Hi. pax> gcc -o xyzzy testprog.c ; ./xyzzy Hi.

a.out is the executable (assuming you've done full compilation rather than just generation of object files but that's the most likely case). To run it, use (from a shell):

./a.out

If you want to give it a different name, simply rename it, or better:

gcc -o actualname myprog.c

to get an executable called actualname which is then run (of course) with:

./actualname

See the following transcript:

pax> cat testprog.c #include <stdio.h> int main (void) { printf("Hi.\n\n"); return 0; } pax> gcc testprog.c ; ./a.out Hi. pax> gcc -o xyzzy testprog.c ; ./xyzzy Hi.
