The following program demonstrates the issue. It prints:
y = 2.000000
CGRectMake symbol not found
What would cause the symbol not to be found when using the dlopen/dlsym functions?
#import <CoreGraphics/CoreGraphics.h>
#import <dlfcn.h>
int main(int argc, const char * argv[])
{
CGRect rect = CGRectMake(1.0, 2.0, 3.0, 4.0);
printf("y = %f\n", rect.origin.y);
void * handle = dlopen("/System/Library/Frameworks/CoreGraphics.framework/Versions/A/CoreGraphics", RTLD_LAZY);
if (handle == NULL) {
printf("handle == NULL\n");
}
else if (dlsym(handle, "CGRectMake") == NULL) {
printf("CGRectMake symbol not found\n");
}
return 0;
}
I am observing this issue with other symbols as well. What is special about them?
