Hi
I had try to compile the following Android.mk file using ndk-build.
I got the following errors. how can I resolve this problem?
please help me.
the make file is
# ================================================== ========
# NOTE:

the error is

Android supports pthreads strating from API 9 version. i got the above error due to i am using old version of NDK. to avoid this build like this "$ndk-build APP_PLATFORM=android-9 "

that is the error that I get when compiling. already investigate but can not find the solution so please thank your answer to be able to repair it and because generating that error thanks
You may need to add the boost_system library. You can add -lboost_system to your linker flags to find related library symbols in Android.mk (Assuming that boost is built as static):
LOCAL_STATIC_LIBRARIES = -lboost_system ...
include $(BUILD_STATIC_LIBRARY)
I am new in NDK and i want to use a c library in my application. I try with a simple c file and it work. I succeded to send and receive data between the two api. But when i want to introduce an existing c library i have this kind of error when i run ndk-build.

How can i solve this problem? I read all the Android.mk documentation but i did not see any thing to solve it. Regards
you said you succeed to create shared library libmy_manager . in Android.mk specify the path of libmy_manager.so and the path of header files
LOCAL_PATH := $(call my-dir)
include $(CLEAR_VARS)
LOCAL_MODULE := libmy_manager
LOCAL_SRC_FILES := libmy_manager.so
LOCAL_EXPORT_C_INCLUDES := $(LOCAL_PATH)/include #path of header file with define
# function in libmy_manager
include $(PREBUILT_SHARED_LIBRARY)
include $(CLEAR_VARS)
LOCAL_MODULE := my_manager
LOCAL_SRC_FILES := my_manager.c
LOCAL_EXPORT_C_INCLUDES := $(LOCAL_PATH)/include
LOCAL_SHARED_LIBRARIES := libmy_manager
include $(BUILD_SHARED_LIBRARY)
I'm tryng to port an iOS game to Android platform with cocos2dx 2.0.4.
The core of the game is written in c++ and we managed to run it on iOS, in fact the game is avaivable on the Apple Store.
I'm using NDK r8d and lastest SDK, but I'm encountering a lot of issues when trying to build.
My application.mk is like this:
APP_STL := stlport_shared
APP_CPPFLAGS := -frtti
NDK_TOOLCHAIN_VERSION=4.7

LOCAL_PATH := $(call my-dir)

LOCAL_MODULE := stlport
endif

Any help much appreciated, thanks...
Try this in application.mk APP_STL := gnustl_static?
You get the above undefined reference error because you have not added the necessary libraries in Android.mk files. It looks something like this
LOCAL_LDLIBS := -L$(call host-path, $(LOCAL_PATH)/../../libs/$(TARGET_ARCH_ABI)) \
-lcocos2d -lGLESv1_CM -llog -lgame_logic
I am stuck with this issue even after adding the libraries. Its got something to do with setting path but I dont know how to..
If you solve this let me know
I am trying to link an executable against libcutils.so, but I get the following error:
Executable : gps_test
/home/jbrew/android_gps/jni/lib_dir//libcutils.so: undefined reference to `ioprio_set'
/home/jbrew/android_gps/jni/lib_dir//libcutils.so: undefined reference to `ioprio_get'
collect2: ld returned 1 exit status
make: *** [obj/local/armeabi/gps_test] Error 1
Here is what my Android.mk file looks like:
LOCAL_PATH:= $(call my-dir)
include $(CLEAR_VARS)
LOCAL_SRC_FILES:= \
gps_test.c
LOCAL_LDLIBS:= -L/home/jbrew/android_gps/jni/lib_dir/ -llog -lhardware -lcutils
LOCAL_C_INCLUDES:= \
/home/jbrew/android_gps/jni/includes
LOCAL_MODULE:= gps_test
#include $(BUILD_SHARED_LIBRARY)
include $(BUILD_EXECUTABLE)
Is there a way to get the compiler to ignore these? I tried to add CFLAG --warn-unresolved-symbols, but the compiler didn't know what that flag meant.
For anyone else that has this issue, the problem was my API level. ndk-build was using android-3 to build by default. I added a default.properties file to my project path, then put "target=android-9" in that file. After this addition, I could build the executable.
Heya,
I'm having trouble building an ndk/jni shared library which I have developed. I am hoping to reuse the libjpeg which ships with the platform (/system/lib/libjpeg.so) however I cannot get it to link. When I build my shared library I get...

Which is essentially every symbol I would need to resolve out of libjpeg.so at runtime...
I have copied libjpeg.so off of my emulator and into my project directory under 'lib'. When I run 'arm-eabi-readelf -s' on that copy of libjpeg.so I can see all of the above symbols defined (I can't see method signatures.. just names.. is there a way to dump signatures/namespaces??)
My Android.mk is as follows...
LOCAL_PATH := $(call my-dir)
include $(CLEAR_VARS)
LOCAL_C_INCLUDES := /opt/android_src/dalvik/libnativehelper/include/nativehelper \
/opt/android_src/frameworks/base/include \
/opt/android_src/system/core/include \
/opt/android_src/dalvik/libnativehelper/include \
/opt/android_src/external/stlport/stlport \
/opt/android_src/external/jpeg \

LOCAL_LDFLAGS += -Llib
LOCAL_MODULE := jnijpeg
LOCAL_SRC_FILES := JNIBmp.cpp
LOCAL_LDLIBS := -lm -llog -ljpeg -landroid_runtime
include $(BUILD_SHARED_LIBRARY)
Thank you much for any help!
Try to use #include in this form:
extern "C" {
#include "jpeglib.h"
}
It worked for me.
Good luck!
I was able to link against -ljpeg using the following:
LOCAL_LDLIBS := -L$(MYDROID)/out/target/product/generic/system/lib/ -ljpeg
