With a simple test program,
%%%
#include <objc/Object.h>
#include <pthread.h>
#include <stdio.h>
@interface Test : Object {
const char *string;
}
-(void) set:(const char *)str;
-(void) print;
@end
@implementation Test
-(void) set:(const char *)str {
string = str;
}
-(void) print {
printf("Test: %s\n", string);
}
@end
id obj;
static void *thr(void *ctxt __unused)
{
[obj print];
[obj set:"Inside"];
[obj print];
}
void main(void)
{
pthread_t td;
obj = [Test alloc];
[obj set:"Threads"];
pthread_create(&td, NULL, thr, NULL);
pthread_yield();
exit(0);
}
%%%
It seems a simple case doesn't break:
(jmallett@luna:~)121% cc test.m -lobjc -pthread
test.m: In function `main':
test.m:31: warning: return type of `main' is not `int'
(jmallett@luna:~)122% ./a.out
Test: Threads
Test: Inside
Simply with using thr-posix.c.
