Add a C++ file to the ccs v5 project

Try changing the #including source file's name to something.C (capital C) and see if that helps.

If not, maybe your header is being compiled by itself (that should not happen..); if it is listed alongside the C and C++ source files, move it to the Includes folder instead.

Thank you for your answer.

I have some questions.

First, I try modify the c file to cpp file. And it would no error when I build the project, but it would errored when I load programming. The cmd file, tcf file and errors as follw:

3527.linker_c6678.rar

0385.tsuApp.rar

5141.error.rar

My question is that what should I do when I use the C++ class in my code. I try use the extern "C", but it can't resolve the class error. Maybe the compiler don't identify the extern "C".

Second, it provide Language Options in CCS, if I can write code in C++ fully. And it provide option of Embedded C++, what affections would be if I choose the option.

Hi, I have a question about the option of Embedded C++.

 I must choose the compiler option of -pe if I add a C++ file to my project? What's the mean of -pe?

Hi, tianxing

You should be able to use C++ normally, the only thing I did different from C was using .hpp header instead of .h. It's strange but solved a problem I was a getting (I'm not sure but I think the problem was the 'class' error message you mentioned).

Do you get these messages just when add the C++ files? They seem to be memory errors.

ti.sysbios.heaps.HeapMem: line 296: out of memory:

In the case above you have to increase the heap you're using or maybe there's a 'delete' missing and you're getting a memory overflow.

The other messages

[C66xx_0] A0=0x0 A1=0x0
[C66xx_0] A2=0x0 A3=0x810cc8

Are hardware error messages, I was getting the same kind of message, I don't know exactly what's their meaning but I saw in some threads in the forum that it's related to physical memory itself. Maybe they're caused by a memory leak.

Hi Johannes,

Thank you for your reply.

I thought the reason of the error is the overflow of memory, And I change the cmd file, the code executed successful.

If my files are .cpp, it would be no error even though I used the class.

I call a function of class in the .c file according to the instruction of http://processors.wiki.ti.com/index.php/Invoke_a_C++_Class_Member_Function_from_an_Interrupt.

Now I have a question about the name mangling.

In the web of http://processors.wiki.ti.com/index.php/Overview_of_C++_Support_in_TI_Compilers#Name_Mangling. I see one feature of C++ is called function overloading because it can mangled the name of function. Now I have a question about that if I used the extern "c" in the C++ code, if it have the feature of function overloading, and if I define two function with the same name and the argument is different, it would be.
