Enum definition error (legal in Visual Studio)

Hi,

 

I would like to ask a question on enum on C6000 compiler.

 

 

A declaration following definition of enum type and variable, which are completely legal in Visual Studio 2008, got error on C6000 compiler.

 

I have also tried the -kr_compatible option but it didn't solve the problem.

 

Why this happens and how should I solve it?

 

Zheng

    In addition, I searched C6000 include folder for file contents containing "enum", and much to my surprise, there is no single file containing enum in their body or even comment.

     

    Is enum deprecated for some reason in C6000 compiler? Why is it not used?

    No, the compiler is not in error.

    The code you have presented is valid C++ code, but it is not valid C code. No doubt you are operating Visual Studio in C++ mode.

    You need to declare this variable as follows, or else use C++ mode:

    enum fruit mine = apple;

    Another way to handle that in C is to use a typedef:

    typedef enum fruittag { apple, orange } fruit;
    fruit mine = apple;
    enum fruittag yours = orange;

    The fruittag identiifer is optional.

    Archaeologist and Norman,

    Both your solutions worked, thanks very much.

    Archaeologis,

    How to turn on C++ mode? Embedded C++ attempts to trim standard C++ to meat performance requirements of embedded applications, which at least shows that C++ might be slower or require more resources than C. I think it is true due to its inheritance, polymorphism and other features. How slow is C++ comparing with C on embedded processors? Are TI software packages {BIOS and others} written in C or C++?

    That is the default for files with extension .cpp.  Or you can use the options --cpp_default or --cpp_file filename.

    Most TI software packages, BIOS included, are implemented in C and assembly.  I'm sure there is a C++ package or two out there, but I can't think of any.

    For all other questions about C++, please see this wiki article.

    Thanks and regards,

    -George
