Build An Linux Executable Using GCC
提问by Nathan Campos
I'm using Linux Ubuntu Intrepid Ibex and compiling C++ files with GCC, but when I compile, gcc makes a.outfile, that is the executable, but how I can make Linux executables? Thanks!
我正在使用 Linux Ubuntu Intrepid Ibex 并使用 GCC 编译 C++ 文件，但是当我编译时，gcc 生成a.out文件，即可执行文件，但是我如何制作 Linux 可执行文件？谢谢！

That executable is a "Linux executable" - that is, it's executable on any recent Linux system. You can rename the file to what you want using
该可执行文件是“Linux 可执行文件”——也就是说，它可以在任何最新的 Linux 系统上执行。您可以将文件重命名为您想要使用的名称
rename a.out your-executable-nameor better yet, tell GCC where to put its output file using
或者更好的是，告诉 GCC 在哪里放置它的输出文件使用
gcc -o your-executable-name your-source-file.cKeep in mind that before Linux systems will let you run the file, you may need to set its "executable bit":
请记住，在 Linux 系统允许您运行该文件之前，您可能需要设置其“可执行位”：
chmod +x your-executable-nameAlso remember that on Linux, the extension of the file has very little to do with what it actually is - your executable can be named something, something.out, or even something.exe, and as long as it's produced by GCC and you do chmod +xon the file, you can run it as a Linux executable.
还请记住，在 Linux 上，文件的扩展名与它的实际情况几乎没有关系——您的可执行文件可以命名为something、something.out、甚至something.exe，只要它是由 GCC 生成的并且您chmod +x在文件上做了，您就可以运行它作为 Linux 可执行文件。

To create a executable called myprogyou can call gcc like this:
要创建一个名为的可执行文件，myprog您可以像这样调用 gcc：
gcc -c -o myprog something.c
You could also just rename the *.out file gcc generates to the desired name.
您也可以将 gcc 生成的 *.out 文件重命名为所需的名称。

That is the executable. If you don't like a.out, you can pass an -o flag to the compiler. If the executable isn't marked with an executable bit, you need to do so youself:
那是可执行文件。如果您不喜欢 a.out，您可以将 -o 标志传递给编译器。如果可执行文件没有用可执行位标记，您需要自己这样做：
chmod u+x ./a.out
./a.out
HTH.
哈。
