Hello there
I was wondering why this piece of code doesn't work by itself on my
mac ?
NSTask *task;
task = [[NSTask alloc] init];
[task setLaunchPath: @"/bin/bash"];
NSDictionary * environment = [NSDictionary
dictionaryWithObjectsAndKeys:@"localhost:0.0",@"DISPLAY",nil];
NSArray * arguments = [NSArray arrayWithObjects: @"-c", @"/usr/
X11R6/bin/xhost + && /sw/bin/nedit", nil];
[task setEnvironment: environment];
[task setArguments: arguments];
[task launch];
It usually throws some error like this:
Xlib: connection to "localhost:0.0" refused by server
Xlib: No protocol specified
/usr/X11R6/bin/xhost: unable to open display "localhost:0.0"
Anyway, a simple xhost + as root can solve the problem.
BUT ... it's weird !
I mean, I should be able to do the xhost + as the user to allow
connection on the local machine don't you think?
So, does anyone knows how to deal with this problem without having to
authenticate ?
Best regards,
Thierry.
