Hi,

I use vision sdk 3.04 for ubuntu. How could I enable optimization and c99/c11 options for gmake? Or where can I read about it?

Thanks for answers.

Hi,

You can add c flags in vision_sdk/build/rtos/makerules/

Please follow the below doc

\PROCESSOR_SDK_VISION_03_03_00_00\vision_sdk\docs\FeatureSpecificUserGuides\VisionSDK_UserGuide_BuildSystem.pdf

Hi,

For example, For A15 add "CFLAGS_INTERNAL+= -std=c99 " enable c99 option, is it right?

Hi,

You can not do like that coz if you modify CFLAGS_INTERNAL it will be same for c and cpp file and for cpp files -std=c99 is not a valid flag.
So add it where it compiling c files only like below

$(OBJ_PATHS): $(OBJDIR)/%.$(OBJEXT): %.c
$(ECHO) \# Compiling $(PLATFORM):$(CORE):$(PROFILE_$(CORE)):$(APP_NAME)$(MODULE_NAME): $<
$(CC) -MD -MF $(DEPDIR)/$(basename $(notdir $<)).P -std=c99 $(_CFLAGS) $(INCLUDES) $(CFLAGS_DIROPTS) -o $(OBJDIR)/$(basename $(notdir $<)).$(OBJEXT) $<
