Re: [avr-gcc-list] calling function pointers via pointers ?

Thank you so much chaps, after an hour experimenting, armed with all your suggestion, I have now improved my understanding of pointers again... and it now works... However, something still causes me trouble apparently The actual/complete declaration of my menu data type / structure is

[avr-gcc-list] avr-objcopy failed to produce coff/ext-coff

Hi, I am using winavr to compile a simple c code with the compiler option dwarf2 enabled. CFLAGS = -ggdwarf-2, but I failed to generate extcoff file. The following is the command line I used to generate the extcoff file, I always get "no recognized debugging information": make extcoff

Re: [avr-gcc-list] calling function pointers via pointers ?

From: Vincent Trouilliez [EMAIL PROTECTED] [...] What more could I possibly want ? Well, there is one thing actually: the pointer points to a function, any function. However if the item is actually a sub-menu, then the 'menu_item' structure needs to store a pointer to a 'menu' structure, so that
