C程序可执行文件帮助-Linux

Question

I just recently made the move to Linux, and now looking to program on it as well.

However, for some reason I cannot get an executable to work.

Here's what I've done:

1. Downloaded Code::Blocks
2. Made a new Console Project in Workspace 1 with C source.
3. Added a getchar() before return(0);
4. Ran and Compiled - Which works perfectly INSIDE Code::Blocks
5. Went to the bin/release folder in which the file is saved, tried double clicking, right clicking and selecting: open, open with, tried using terminal to run the name of my program. I copied the folder URL, and then name of the file.. I just can't seem to get the created file to execute!

In windows it made a .exe, I know there is no ending (?) in linux. (Could be wrong).

I'm currently running Ubuntu 11.04.

Answer 1

Most Linux distributions don't include the current directory in the PATH variable that determines where to search for executables. Try opening a terminal, changing to the bin/release directory and explicitly qualifying your executable for the current directory:

./myprogram

This is in contrast to Windows, where you can simply type "myprogram.exe".

Answer 2

您可能需要授予程序权限才能作为可执行文件运行：

sudo chmod +x yourProgram

Answer 3

In the terminal emulator, go to (cd) the folder where the executable is created.

Type ./programname

Where programname is the name of the executable file (./ tells the shell to look in the current directory for the program to run)
