MSVStudio #define passed to C/C++ per configuration

[wademaxfield]

I googled, and searched in the forums, but could not find an answer.

I am sure I am overlooking something obvious.

I have a mix of Java and C code, with flavors.

I would like to set up a #define and pass it to the C/C++ compiler on a per-configuration basis, to support different flavors.

I tried the Makefile Settings, but the CXXFLAGS shows up on *all* configurations/flavors.

For now, I have to manually change the #define in a header file for each flavor I compile.

Can someone tell me how to do this?  I’m rather dumb when it comes to this, so more information is better than less information. I usually end up puzzled with answers.

You can add something like “MYVAR=1” to the ndk-build command-line arguments and then check it from your Android.mak:

ifeq($(MYVAR),1)
LOCAL_CFLAGS += -DTEST
endif

Let us know if you need more details.

Thank you for your reply.  Unfortunately, that does not work, but thanks for trying!  It may not be possible under android.

 

in My Android.mk file:  (also tried LOCAL_CPP_FLAGS)

LOCAL_PATH    := $(call my-dir)
include $(CLEAR_VARS)

ifeq ($(AVB_VER),1)
LOCAL_C_FLAGS += -DAVB_OVERRIDE
LOCAL_C_FLAGS += -DAVB_BEGINNER_VER
endif

in my header file:

#ifdef AVB_OVERRIDE
#ifdef AVB_AVB_BEGINNER_VER
#pragma message(“Beginner Defined”)
#define IVB_VERSION_NUMBER IVB_BEGINNER
#endif

#ifdef AVB_AVB_BASIC_VER
#pragma message(“Basic Defined”)
#define IVB_VERSION_NUMBER IVB_BASIC
#endif

#else
#pragma message(“version defined inside ivdefines.h”)

#define IVB_VERSION_NUMBER IVB_BASIC /* ivb pro is 4.0*/
#endif

 

in my output:

VisualGDB: Run “c:\android-ndk-r10d\ndk-build.cmd NDK_DEBUG=1 APP_PLATFORM=android-14 VGDB_VSCONFIG=Debug__BeginnerFree_ AVB_VER=1” in directory “C:\Users\cti\Dropbox\AVBasic\AVBasic\app” on local computer

Note that even though I had an inner #ifdef incorrect (AVB_AVB_BEGINNER_VER), my answer still stands.  The AVB_OVERRIDE path was obviously not taken.

OOPS!!!!!! FOUND IT!!! LOCAL_CFLAGS, not LOCAL_C_FLAGS!!!!
