Compiling a C program to Mac OSX

maginotjr · 02-06-2008, 04:39 PM

Sorry by the lazyness, but is just Im needing this very quickly and there is no time to learn C, so I think that maybe someone could help me with the code to run this commmand: "mount -t msdos /dev/disk1s1 /mnt/disk".

I was thinking making in C and place in the desktop of the users (I will modify a litle the command line above) I tried just a exec file but Mac OSX opens it on the editor...

Thanks!

What’s wrong with using a script? Did you give it correct (i.e., execute) permissions?

Isnt user friendly and will make the user to go to the console everytime he want to load the script, and the user isnt used to shell.

So I think that an icon on the desktop could be mutch more easy.

I thought you could click-to-execute a script the same way you click-to-execute a binary (as long as both of them have execute permissions). I haven’t used OSX in awhile, but I thought that’s how it worked.

If not, you can always use execl() in a C program:

Code:

execl("/path/to/script", "0th argument", "1st argument", "2nd argument", "3rd argument", 0);

the 0th argument is usually the basename of the file. The rest of the arguments are what you normally think of as arguments. The last parameter of the function is a 0, and tells the C library that you are done passing parameters.

You just need to figure out how to do it properly in Mac OS X. You can have a script on the desktop that just does what it is supposed to do rather than opening the console or editor. I'd have to dig into it to see how, but the Mac specialist at work does that for the computer lab all the time.

[quick and dirty]

Code:

#include "stdio.h"

main(int argc, char *argv[])
{
        system("mount -t msdos /dev/disk1s1 /mnt/disk"); // consider using -t vfat
// not sure what /dev/disk1s1 refers to but i assume its like /dev/hda1
}

does mac have gcc ? i remember making a skype like script to cat /dev/dsp to an open port but mac doesnt have netcat. you might be able to compile this on linux and scp the program-binary to the mac system (it should run since osx is posix compliant and now use x86 processors). else dual boot (is there a live-cd available for mac) and use the gcc on linux to compile the program on the mac hardware after mounting the mac harddrive.

im sorry this is all theoretical but i dont have a mac to test this out on but i am still curious to know what works and what doesnt.
