Re: error: expected method to write dictionary element not found on object of type 'NSMutableDictionary *

[Christopher Lloyd]

Hi,

The containers don't implement support for  the new subscripting, should be fairly simple to do, the methods are explained here:

http://clang.llvm.org/docs/ObjectiveCLiterals.html

The NSMutableDictionary doc's describe their implementation, same as objectForKey/setObject:forKey:

I have been trying to port an Objective-C program from Apple Xcode 4.5.2 which compiles perfectly to Linux CentOS 6.4 using Cocotron.  I am using the GNUstep runtime with clang 3.3.  I am getting hundreds of "expected method to write..." errors.  For example:

/root/GenealogyText/Library/

Source/Analysis/GTActionTable.m:38:5: error: expected method to write dictionary element not found on object of type 'NSMutableDictionary *'
    _functionMap[entry.name] = entry;
    ^
/root/GenealogyText/Library/Source/Analysis/GTActionTable.m:49:17: error: expected method to read dictionary element not found on object of type 'NSMutableDictionary *'
        entry = _functionMap[name];
                ^
/root/GenealogyText/Library/Source/Analysis/GTActionTable.m:66:37: error: expected method to read dictionary element not found on object of type 'NSMutableDictionary *'
        GTActionTableEntry* entry = _functionMap[key];
                                    ^

The Apple compiler is happy with this newer way of writing this.  If I revert back the following it compiles on CentOS fine:

 //    _functionMap[entry.name] = entry;
      [_functionMap setObject: entry forKey: entry.name];

//        entry = _functionMap[name];
          entry = [_functionMap objectForKey: name];

//        GTActionTableEntry* entry = _functionMap[key];
          GTActionTableEntry* entry = [_functionMap objectForKey: key];

I guess my question boils down to knowing if this functionality has been added and I am just missing something or if it is not possible to do at this point? With hundreds of these to change, it is a daunting task.  I am hoping that someone with a lot more experience than me will have an answer that would make that unnecessary.

Thanks in advance for anyone that can shed some light on this.
