I really would like my build to generate as many warnings as possible, when it makes sense. I'm using SES 3.34a

In SES IDE, Tools > Options:
The Compatibility section of the Build Environment Options shows the following:
-Wall;-Wextra;-Wstrict-prototypes

I can't seem to find any such thing in Project Options.

However when the build is executed from the IDE, I do not see -Wall -Wextra etc, as can be seen below (I have eliminated the include paths from the build ouptut below):
"C:/Program Files/SEGGER/SEGGER Embedded Studio for ARM 3.34a/gcc/arm-none-eabi/bin/cc1" -fmessage-length=0 -fno-diagnostics-show-caret -mcpu=cortex-m4 -mlittle-endian -mfloat-abi=hard -mfpu=fpv4-sp-d16 -mthumb -mtp=soft -nostdinc "-isystemC:/Program Files/SEGGER/SEGGER Embedded Studio for ARM 3.34a/include" "-isystemC:/Users/kkw/AppData/Local/SEGGER/SEGGER Embedded Studio/v3/packages/include" -D__SIZEOF_WCHAR_T=4 -D__ARM_ARCH_7EM__ -D__SES_ARM -D__ARM_ARCH_FPV4_SP_D16__ -DNDEBUG -DBL_SETTINGS_ACCESS_ONLY -DBOARD_PCA10056 -DCONFIG_GPIO_AS_PINRESET -DFLOAT_ABI_HARD -DINITIALIZE_USER_SECTIONS -DNO_VTOR_CONFIG -DNRF52840_XXAA -DNRF_DFU_SVCI_ENABLED -DNRF_DFU_TRANSPORT_BLE=1 -DNRF_SD_BLE_API_VERSION=6 -DS140 -DSOFTDEVICE_PRESENT -DSWI_DISABLE0 -DUSE_APP_CONFIG -DDEBUG -MD "C:/git/an-3/nRF5_SDK_15.0.0_a53641a/project/ble/efgh/pca10056/s140/ses/Output/abcd Release/Obj/xyz.d" -MQ "Output/abcd Release/Obj/xyz.o" -quiet -g3 -gpubnames -std=gnu99 -fomit-frame-pointer -fno-dwarf2-cfi-asm -fno-builtin -ffunction-sections -fdata-sections -fshort-enums -fno-common C:\git\an-3\nRF5_SDK_15.0.0_a53641a\project\ble\efgh\qrst\xyz.c -o "C:/git/an-3/nRF5_SDK_15.0.0_a53641a/project/ble/efgh/pca10056/s140/ses/Output/abcd Release/Obj/xyz.asm"

I tried using emBuild with the same result.

How do I get the compiler to enforce this setting, of -Wall;-Wextra?

Thanks & regards

Hi Nino,

As always, thanks. This solved my problem.

Here's the interesting thing: After enabling -Wall,-Wextra;-Wstrict-prototypes, the compiler warned me that in a switch statement, I had misspelled "default" to "defaut" (the letter l is missing). Without adding these warnings, the compiler silently accepted it as a standard C label.

Now that I now know where the options are, it's fine. Some suggestions:

• Between Tools > Option > Build > Compatibility and the actual Project Options, it is confusing.
  
• The Enable All Warnings is in Code Generation. I think it should have been in Project Option > Compiler OR Project Options > Build, since Enforce ANSI C checking is in Project Options > Compiler.
  

I do appreciate your quick response. This matter is closed.

Regards,
Kannan
