__attribute__((used)) not recognized

Hi,

I have to compile a function which is not referenced thus I try to use the __attribute__((used)) keyword. But I encounter some issues, the compiler does not recognise it.

Here how i used it:

void my_function (void) __attribute__((used));

void my_function(void) {

blabla (); }

And here is the result :

Building “my_project” in configuration “MAXQ30 Debug”
Compiling main.c
found '__attribute__', expecting ';'
found '(', expecting ')'
missing prototype
found ')', expecting ';'
Build failed

Does anyone have a clue ?

Thanks

- Emilien

Hi Emilien,

"__attribute__((used))" is a GNU specific compiler directive.

You could use the Linker Options > Keep Symbols project property. You need to add a leading underscore, so for your above example you would set the property to _my_function.

Hi Jon,

thanks for your response.

I gave it a try before but did nut put the '_' before my_function.

Now it works perfectly
