macOS Xcode: stdio.h not found

maya90 · Feb 17, 2011

hi,

from this tutorial
http://mobile.tutsplus.com/tutorials/iphone/learn-objective-c-day-1/

Code:

#include <stdio.h> 
int main(){ 
     printf("Hello World\n"); 
     return 0; 
 }

to compile did:

gcc program1.m -o program1

got msg:

stdio.h not found

so searched for it... found here:

/Developer/SDKs/MacOSX10.6.sdk/usr/include/

so in program I put

#include </Developer/SDKs/MacOSX10.6.sdk/usr/include/stdio.h>

but got error on compiling... TONS of errors, too many to paste here...

would appreciate some help..

thank you..

(PS: is there a "watch this thread" feature on these forums?? thank you...)

You definitely missed something or your Xcode/gcc is not configured correctly.

Please use the CODE tags around code you post, it makes things far easier to follow. You should NOT have the extra "#"s in the code. Use the "View plain" button on the site you are using to allow for easier copy & paste.

Putting

Code:

#include <stdio.h>
int main(){
    printf("Hello World\n");
    return 0;
}

in a file called program1.c on the Desktop and running

Code:

cd ~/Desktop
gcc program1.c -o program1

from Terminal.app works absolutely fine here.

Yes, thread subscriptions.

oh -- you're saying it works on your machine? but it doesn't work in mine!! ;-)
so what do I do.. I posted location of stdio.h... so: do I need complete path to it? how does compiler find it????

thank you...

Investigate.

Add the -v flag to gcc and post the actual output to the thread. Here's mine that works.

Code:

EDIT: You think perhaps it might have something to do with whatever you did to change the default location of Xcode? https://forums.macrumors.com/threads/1097914/

no idea what all this means... would very much appreciate some help.. (as posted previously, stdio.h IS there, it's at

actually it's at a lot of diff locations...

(and to reply to another poster, no, I have not changed location of Xcode install or anything else..)

Code:

ignoring nonexistent directory

Xcode didn't install properly. It should create all of those missing folders during install.

Repair permissions for fun and then reinstall Xcode. http://guides.macrumors.com/Repairing_Permissions

oh brother.. I can't believe this..........:-(

now I downloaded from here,
https://developer.apple.com/devcenter/ios/index.action

downoaded from this link
Xcode 3.2.5 and iOS SDK 4.2
on above page

(now when I install I get a very diff install window from what's here,
http://www.macworld.com/article/46286/2005/08/installxcode.html
if you scroll down you will see a window "Install Xcode Tools" -- in my case what appears on this window is very different from what appears here..)

(and yes something must be wrong b/c I also had to set path for gcc location, but I've read that the install puts gcc location in path for you...)

thank you..

I would hope so. That page was for Xcode 2. Clearly what you installed even at first wasn't that.
