Sorry, I was trying not to send the whole code, probably should have
included that.
Anyway still looking for an answer, I believe it has something to do with
the way I am compiling from source since I don't see a Libraries folder
under /usr/GnuStep
#include <stdio.h>
#import <Foundation/Foundation.h>
/*
* The next #include line is generally present in all Objective-C
* source files that use GNUstep. The Foundation.h header file
* includes all the other standard header files you need.
*/
/*
* Declare the Test class that implements the class method
(classStringValue).
*/
@interface Test
+ (const char *) classStringValue;
@end
/*
* Define the Test class and the class method (classStringValue).
*/
@implementation Test
+ (const char *) classStringValue;
{
return "This is the string value of the Test class";
}
@end
/*
* The main() function: pass a message to the Test class
* and print the returned string.
*/
int main(void)
{
NSString* s = @"Hello, world!";
NSLog(s);
//printf("%s\n", [Test classStringValue]);
return 0;
}
Same issue is still happening
