Error [LI006] - STM32L1xx - IAR - Linker error: Duplicate Definition

Hi,

I have modified an example project of IAR for STM32L1XX with a new library definition (one file .c and one file .h). In the file .h I have defined a variable that I use in the .c file. The function defined in the .h file are developed in the .c file and used in the main file.

There aren't any duplicate of the variable that I have defined in the .h file, but when I run the make command I can see this message:

One error for variable defined in the .h file. Why?

Can you help me?

Best Regards

One error for variable defined in the .h file. Why? Can you help me?

Yet you don't provide the file(s) to examine, or a brief snap-shot.

If I have to guess, you are defining variables without using ''extern'' and consequently every file which includes your .H creates a copy of the variable.

foo.h -> extern int bar;

foo.c -> int bar = 0;

main.c -> #include ''foo.h''

I have the same pb, my usage is like follows:

#ifdef INIT_AVER

init.h -> int aver;

init.c -> aver = 0;

#endif

main.c -> #include ''init.h''

Try this:

init.h -> extern int aver;

Thanks, I will try.

When I use ''extern'' in init.h, I got the following error:

Error[Li005]: no definition for ''aver'' [referenced from ....\main.o]

Your distribution of declaration in source files is not clear to me from this posts.

However, one file should define the questioned variable:

int  variable = 0;

or:

extern int  variable = 0;

The other file should see a declaration, for instance from a header:

extern int  variable;

Each variable must be defined once and only once, but can be declared multiple times.

See a C language manual for the difference between definition and declaration.

Yes, this is just I did, the only declaration is in init.h, and it is affected by a value in init.c. There is no any other declaration. This is why I can not understand where is the pb.
