In order to use Lisp code within an application built using Xcode, the main function of the application must call LispWorksInitialize. For example, main might be implemented like this:
#import "LispWorks.h"
int main(int argc, char *argv[])
{
if (!LispWorksInitialize(argc, argv)) abort();
@autoreleasepool {
return UIApplicationMain(argc, argv, nil, NSStringFromClass([OthelloAppDelegate class]));
}
}
LispWorksInitialize is automatically included in the object file generated by deliver. The file LispWorks.h can be found in the examples/ios/OthelloDemo/OthelloDemo/ directory of the LispWorks installation and should be copied into the Xcode project.
