Hello!
I'm a newbie of this site. My question is about Linux/ Unix in general. Basically, I used gcc / g++ to compile codes from my computer and obtain an executable file. (This executable file is a result of linked multiple *.o files.) Then I need to transfer this executable file to a different computer to run it. But the file seemed to corrupt under ftp. (I ftp it as a binary file.) When I run this executable file on that computer, it complaint "Exec format error. Binary file not executable." Does anybody have any idea what's going on here? Is it possible for me to transfer this executable file somehow without getting into this problem? Thank you for your help/ suggestion.

What are you using to transfer the file? standard ftp or sftp?

Before starting make command
chmod a+x you_file

I used standard ftp and gFTP (graphic ftp). Both of them don't work. But I will try to chmod a+x before doing ftp. Thanks for all suggestions. : )

Use the command:

type binary

At the FTP prompt after connecting to the FTP server.

AFTER ftp.

1. You compile program.
2. You transfer program with ftp on other machine
3. chmod a+x your_program
4. cd your_dir; ./you_program
