How do I make the following linker waing about a wrong exte declaration an error? I am compiling & linking with gcc version 4.8.3 Sourcery CodeBench
uilding target: xxxxx.elf Invoking: Cross ARM C++ Linker arm-none-eabi-g++ -mcpu=cortex-m4 -mthumb -mfloat-abi=softfp -mfpu=fpv4-sp-d16 -O0 -fmessage-length=0 -ffunction-sections -fdata-sections -flto -g3 -T "..configstm32f4emsSTM32F407xG_CCM.ld" -Xlinker --gc-sections -Wl,-Map,"rusefi.map" -Wl,-Map,"rusefi.map" -mcpu=cortex-m4 -mthumb -g3 ....
xxx.cpp:584:21: waing: type of 'afrMap' does not match original declaration [enabled by default]
exte fuel_Map3D_t afrMap;
I would like this to not succeed so that I do not miss the issue again.
