I've completed a simple numbers-version of the game "Towers of Hanoi" using xcode's command line tool in C++. Being accustomed to PC compilers like borland's and visual-c, I've attempted to "share" the game with others via e-mail by simply attaching the executable product built by xcode. However, the recipients can't run the program as it shows up in a different format - usually machine code, it sounds like.
After a bit of extensive searching, I'm realizing the complexity of building projects within xcode's IDE and the variations on the build settings/ targets, etc.
Anyone know how to build a self-contained c++ executable to be universally run? I don't go outside the STL library for this game. I'd greatly appreciate any help.
thanks
OS X is based on Unix, which uses plain binary files (i.e. no filename extension) as executables. If they have a certain "executable permission," they can be double-clicked to be run as executables, or run from the command line. However, this permission can't be sent over email - it's metadata within the file system itself, and this makes sense from a security standpoint (you wouldn't want spammers sending you executable viruses over email right?). So when the recipient receives the binary, they'll need to run the following command line command on it, assuming "hanoi" is the name of the binary file:
chmod +x /path/to/hanoi
If you really want to package it as an instantly double-clickable application, you'll need to give it a native UI and package it as a .app, then put that .app (which is actually a folder with the .app extension) in an archive to distribute. Sorry if that's more work than you were hoping for. Hope this helps!
