324 "Undeclared identifier 'testFunction' in expression"

[keesdeboer]

Dear all,

I've got a problem. I hopeIi can get some tips from you.

I am running the newest version of mikroC PRO for PIC32 v.2.5.1

I am working on a project for a few months now. To keep the project clear, I create sepereate .c files, with their header files. Yestereday I added a new .c and his header file and added them to the project. But this time I ran into a problem. It seems that the compiler, for some odd reason, can't reach those files. When I comile my project i get the error: "Undeclared identifier 'testFunction' in expression".

My code:
Main.c:

Code: Select all

#include "main.h"
//lots of more includes here
#include "testheader.h"

void main()
{
    //lots of functions
    testFunction();
    //more functions;
}

my testFunction.c looks like this:

Code: Select all

#include testFunction.h

void testFunction()
{
    //do something
}

and testFunction.h looks like this:

Code: Select all

#ifndef _TESTFUNCTION_H
#define _TESTFUNCTION_H

//function prototypes
void testFunction(void);

#endif

When I add the content of testFunction.c and testFunction.h in a existing .c and .h file it works fine.

Regards,
Kees

Could be that you are including the wrong header file?

#include "testheader.h"

[keesdeboer]

Thanks for the reply, pwdixon.

I am very certain that I used the correct name for the include file. If I click with my right mouse button on the name of the headerfile, and click in the popup window on 'Find Declaration', the editor opens the headerfile.

So thats why I am very certain.

Regards,
Kees

Code: Select all

#include "main.h"
//lots of more includes here
#include "testheader.h"

void main()
{
    //lots of functions
    testFunction();
    //more functions;
}

so what's "testheader.h"?

Hello,

I have tested the same situation and it definitely compiles fine.
Please check if the both sources are included in Project Manager, and if the Search paths for header file is correct.

To check this open View->Project Manager, and Project->Edit Search Paths

I assumed that testheader.h is the same as testfunction.h

Best regards.

[keesdeboer]

Thank you for the advice, janko.

Because our company is closed for one week (holidays), I am not able to try this out. If I am back, I will try it out.

And yes, testheader.h is the same as testfunction.h (type error from me)

Regards,
Kees

Hello,

Can you tell me which MCU you are using?
Also, can you zip and send me your project for review?

Kind regards,
Jovana
