Identifier Class Is Undefined Iar
vote favorite Using: VS2010 : New Project -> Windows32 Console App -> Empty Project Language: C++ Problem: I'm attempting a simple interface test with two classes that implement the interface through the 1 virtual method. I also attempt to use constructors within those two classes to set default values. The main problem occurs when attempting to create an object of either class; the IDE complains the identifier "class" is is undefined c++ undefined. I have checked tens of other posts with the same error but most of them are errors in instantiation(proper term?) where they use Class obj(); instead of Class obj; another issue in the other threads was that the header files were not included in main.cpp AND the concrete class(proper term?). Still other issues involved the ordering of includes(base class should be first), or even improper use of constructors/deconstructors. I have checked over those issues to see if they would work for me but have been unable to figure out what the problem is. Any insight would be appreciated!

Next Thread | Thread List | Previous Thread Start a Thread | Settings Details Message Read-Only AuthorLeon Montgolf Posted11-Sep-2008 22:00 GMT ToolsetARM C++, works maybe? Leon Montgolf I put a simple class in a file named "test.h". The class is as follows: class a { public: int b; }; I am using the Keil MCBSTM32 board (STM32F103RB processor). I place this file in "C:\Keil\ARM\Boards\Keil\MCBSTM32\Timer". I then open the timer project. If I include the file in timer.c I get the following error: Build target 'MCBSTM32' compiling Timer.c... test.h(2): error: #20: http://stackoverflow.com/questions/30069372/c-interfaces-error-identifier-class-is-undefined identifier "class" is undefined test.h(2): error: #65: expected a ";" Target not created Why does it give me an error? I thought the compiler ssuported C++? Read-Only AuthorAndy Neil Posted11-Sep-2008 23:17 GMT ToolsetARM RE: If I include the file in timer.c Andy Neil Many compilers look at the file type (extension) to decide whether they should be treated as C++ or ANSI 'C' Commonly, .c is taken to mean ANSI 'C' - so you http://www.keil.com/forum/13186 would expect to get errors from C++ stuff... What does the Manual say? Read-Only AuthorLeon Montgolf Posted12-Sep-2008 14:15 GMT ToolsetARM RE: If I include the file in timer.c Leon Montgolf As far as I could determine the Manual or nothing I was able to locate with a search in this forum said anything on C++ compilation, therefore the question. I did not realize that there was a possibility that the extension had anything to do with the compilers ability to recognise C++. I have worked with compilers where you could intermix C and C++ in ".c" file. Most of the time I have worked exclusively in either C or C++. I must admit, I have never tried this particular scenario.

You cannot combine them together."class" word does not exists in C.You have 2 options:1. Convert your cpp file to C or2.
