c - What is the compiler warning option for catching array length mismatches? -


i did not dig enough on own, thank time , responses.

in actual code (proprietary embedded) header extern's #ifdef'ed , default not create them when .c included .h. when set option did produce warnings (errors actually) had wanted.

i have header with:

extern int array[10];

and source file with:

int array[2] = {0, 0};

clearly incorrect. how can cause compiler warn me? error acceptable well.

compilers of interest me gcc (old, 3.4.5) , tasking (not new, 2.3r3). note succeed @ not making error supplier code generation application apparently this. of course, getting application fixed important , can write script compare files, general compile time solution catch error in cases preferred.
