Hi, Is it possible to run Objective-C code in lli? lli does not seem to want to load Foundation.framework. Please see below. Thanks, Eric Brunstad #import <Foundation/Foundation.h> int main(int argc, char *argv[]) { NSAutoreleasePool *pool = [[NSAutoreleasePool alloc] init]; NSLog(@"test!"); [pool drain]; return EXIT_SUCCESS; } cmu-351714:llvm-2.5 ericbrunstad$ /Users/ericbrunstad/Downloads/ llvm-2.5/Release/bin/lli -force-interpreter=true -stats /Users/ ericbrunstad/Desktop/test/test.o -load=/System/Library/Fr...

If anyone happens to be able to test-rig XCode 4 (in iPhone mode with LLVM2 as compiler) vs the code below, it reproduces the problem: template <typename I0,typename I1> void (^ cc(void (^f)(I0,I1), I0 i0))(I1) { ^ void (I1 i1) { }; } int main(int argc, char *argv[]) { NSAutoreleasePool * pool = [[NSAutoreleasePool alloc] init]; cc(^ void (NSString * a, id b) { NSLog(a, b); }, @"%@"); [pool drain]; } Thanks, Matt
