Same old issues with SDL_TTF giving undefined reference

Coder_Bear · April 8, 2013, 2:44am

First I would like to start with that I’m using the following setup

OS: Windows 7 (x86)
IDE: Eclipse 4.2 (Juno)
NDK: r8e

After getting it to recognize that ftbuild2.h and SDL.h do in fact exist in the places that they are pointing to and go to build it. It builds SDL2 without issue, the freetype library and SDL_ttf to an extent. It however then gives me the following errors.

Android.mk:

Code:
LOCAL_PATH := $(call my-dir)

include $(CLEAR_VARS)

LOCAL_MODULE := SDL2_ttf

FREETYPE := $(LOCAL_PATH)/freetype

LOCAL_C_INCLUDES := $(LOCAL_PATH) $(LOCAL_PATH)/…/SDL/include $(LOCAL_PATH)/…/freetype/include $(LOCAL_PATH)/include
LOCAL_CFLAGS := -Os

LOCAL_CPP_EXTENSION := .cpp

LOCAL_SRC_FILES := SDL_ttf.c

LOCAL_SHARED_LIBRARIES := SDL2
LOCAL_STATIC_LIBRARIES := freetype
LOCAL_LDLIBS := -lz

include $(BUILD_SHARED_LIBRARY)

And no the original SDL_TTF I downloaded did not function at all and I had to go back to this solution for it to work to this point. I would really like help in getting this to function so I can port my games to Android. Why does this have to be so difficult?

Did you look at SDL_ttf’s Android.mk? It looks for the freetype directory
as a subdirectory (of SDL_ttf). Maybe that would help.

Android.mk:

Code:

LOCAL_PATH := $(call my-dir)

include $(CLEAR_VARS)

LOCAL_MODULE := SDL2_ttf

FREETYPE := $(LOCAL_PATH)/freetype

LOCAL_C_INCLUDES := $(LOCAL_PATH) $(LOCAL_PATH)/…/SDL/include
$(LOCAL_PATH)/…/freetype/include $(LOCAL_PATH)/include
LOCAL_CFLAGS := -Os

LOCAL_CPP_EXTENSION := .cpp

LOCAL_SRC_FILES := SDL_ttf.c

LOCAL_SHARED_LIBRARIES := SDL2
LOCAL_STATIC_LIBRARIES := freetype
LOCAL_LDLIBS := -lz

include $(BUILD_SHARED_LIBRARY)

And no the original SDL_TTF I downloaded did not function at all and I had
to go back to this solution for it to work to this point. I would really
like help in getting this to function so I can port my games to Android.
Why does this have to be so difficult?

Still not build for me. Please note that SDL2, SDL_Image, and the freetype library all built without an issue.

This is the Android.mk file for SDL_TTF:

Code:
LOCAL_PATH := $(call my-dir)

include $(CLEAR_VARS)

LOCAL_MODULE := sdl_ttf

LOCAL_C_INCLUDES := $(LOCAL_PATH)/…/SDL/include
LOCAL_C_INCLUDES += $(LOCAL_PATH)/…/freetype/include
LOCAL_C_INCLUDES += $(LOCAL_PATH)/…/freetype/include/freetype
LOCAL_C_INCLUDES += $(LOCAL_PATH)/include
LOCAL_CFLAGS := -Os

LOCAL_SRC_FILES := SDL_ttf.c

LOCAL_SHARED_LIBRARIES := SDL2
LOCAL_STATIC_LIBRARIES := freetype
LOCAL_LDLIBS := -lz

include $(BUILD_SHARED_LIBRARY)

This is the current Build Log
