Re: Launch Path Not Accessible
Steve:
You don't need to chmod the file NSTask is really meant for executing
Mach-I executables, so the launch path needs to be the interpreter.
For example, if this is a ruby script your launch path would be /usr/
bin/ruby and your first argument would be the first argument. If it's
a shell script you would use /bin/sh and the script would be the first
argument (and so on and so fourth).

Somehow you're building an object file, not an executable. If you're
building in Xcode, you'll want to use the "CoreFoundation Tool"
project template, or the Carbon->Shell Tool target template. If you're
not building in Xcode, build in Xcode.

Does it take that much extra effort to explain that this tool is to
facilitate relaunching your application? It's a pretty standard
technique, and avoids the inevitable "this makes no sense!" reaction
from the "trust me".

Re: Launch Path Not Accessible
Andrew:
Thanks for the slap on the head!
So I chmod'ed the file and no longer get the 'not accessible error'
YEAH!
BUT now I get:
*** NSTask: Task create for path '/Users/steve/Library/Application
Support/XYZ/Scripts/myUseful.o' failed: 88, "Malformed Mach-o file"
So I must be missing something about the contents of script files.
Here's my script:
myUseful.m
#import
int main(int argc, char **argv)
{
char dummy;
read(STDIN_FILENO, &dummy, 1);
[NSAutoreleasePool new];
NSURL *url = [NSURL fileURLWithPath:[NSString
stringWithUTF8String:argv[1]]];
LSOpenCFURLRef((CFURLRef)url, NULL);
return 0;
}
You will just have to trust me that I DO need to launch the file in
this manner.
What do I need to do to this file to make it into the correct format?
THANKS AGAIN for the chmod help!

I have the static script stored as a separate file in my bundle.
I have created a folder in my "Applications Support" directory

Are you sure myUseful.script is directly executable? Just because
it's double-clickable in the Finder doesn't mean it's executable...
if this is an AppleScript, though, you may have better luck working
with NSAppleScript.
So, thinking that the 'space' maybe wanking out the 'setLaunchPath'
I tried to convert to a 'safe' url path:
NSURL *myScriptFileURL = [NSURL fileURLWithPath:t];
...
[task setLaunchPath:[myScriptFileURL absoluteString]];
Nope. NSTask takes a filesystem path, not a URL.

Launch Path Not Accessible
Folks; I'm trying to do something that seems like it should be easy, but I'm stymied by what I think is a permissions error I don't understand. I'm trying to run a script using NSTask. I have the static script stored as a separate file in my bundle. I have created a folder in my "Applications Support" directory called "Scripts" and copied my script and several items into this directory. Note that this has a space in the full pathname! SO I have tried the following: NSString *myScriptPath = [[self scriptsFolderPath] stringByAppendingPathComponent:@"myUseful.script"]; //yes I have verified this is a valid path!!! NSTask *task = [[[NSTask alloc] init] autorelease]; [task setLaunchPath: myScriptPath]; [task setArguments:[NSArray arrayWithObject:...]]; [task setStandardInput:[NSPipe pipe]]; [task launch]; ERRROR: launch path not accessible So, thinking that the 'space' maybe wanking out the 'setLaunchPath' I tried to convert to a 'safe' url path: NSURL *myScriptFileURL = [NSURL fileURLWithPath:t]; ... [task setLaunchPath:[myScriptFileURL absoluteString]]; Same error! The docs don't make it clear TO ME why I would need special permissions to launch a script in my own "App Support" directory. Am I out in the weeds chasing the wrong rabbits? Any guidance appreciated!
