I have generated Uclib using buildroot and used it to compile mpich for ARM devices.Then I created Android project and copied libmpich.a and the Include folder to the project here is the Android.mk:
LOCAL_PATH := $(call my-dir)
# static library info
LOCAL_MODULE_FILENAME:= libmpich
LOCAL_MODULE := libmpich
LOCAL_SRC_FILES := ../prebuilt/libmpich.a
LOCAL_EXPORT_C_INCLUDES := ../prebuilt/include
LOCAL_STATIC_LIBRARIES := libmpich
include $(PREBUILT_STATIC_LIBRARY)
# wrapper info
include $(CLEAR_VARS)
LOCAL_C_INCLUDES += ../prebuilt/include
LOCAL_MODULE := ndk1
LOCAL_SRC_FILES := native.c
LOCAL_STATIC_LIBRARIES := libmpich
include $(BUILD_SHARED_LIBRARY)
after ndk-build i got the following error

I don't understand why it is not linking correctly and what is missing
Update :
when I add libmpl.a to the project all MPL errors disappeared
I think your problem occured because your static lib libmpich.a has dependance on another lib.
You have two diffenrent way to solve this issue :
Import any library needed by your libmpich.a as static library in your Android.mk as static library. The problem of this approach is that can be very long and painful if you have a lot dependance.
Build libmpich as a dynamic library, as dynamic library are package with their dependance. I do know how you build you libmpich library so i don't know if this will be hard to achieve. Once you have libmpich.so import it in your Android.mk as a dynamic library instead of a static one.

The function infinite() is part of C99. Add LOCAL_CFLAGS += -std=c99 to your Android.mk. See question How to set standard c99 for compile android NDK project
There have been some questions similar to mine, but it seems that their solutions don't work for me.
I'm trying to compile dumpsys source code using Android NDK. I have added a couple of lines to Android.mk to include the libraries.
The final Android.mk file looks like this:
LOCAL_PATH:= $(call my-dir)
include $(CLEAR_VARS)
LOCAL_SRC_FILES:= \
dumpsys.cpp
LOCAL_SHARED_LIBRARIES := \
libutils \
liblog \
libbinders
ANDROID_SRC="my android source directory"
LOCAL_C_INCLUDES := ${ANDROID_SRC}/frameworks/native/include \
${ANDROID_SRC}/system/core/include
#$(warning $(TARGET_C_INCLUDES))
LOCAL_MODULE:= dumpsys
TARGET_ARCH := arm
TARGET_ARCH_ABI := armeabi-v7a
include $(BUILD_EXECUTABLE)
when I execute ndk-build, I get the following errors:

How should I solve this issue?
Thanks in advance.
I'm working on a similar issue here.
Basically, dumpsys is an AOSP component and intended to be built with the AOSP toolchain. You will need to apply some tweaks to port it to NDK – including stuff from ${ANDROID_SRC} is the first step but not the whole story.
You've successfully included the headers and thus made the compiler happy. Now the linker is complaining because it cannot find the libraries you are linking against. The good news is that they are shared libraries, thus having the libraries around at build time isn't a strict requirement.
The NDK defines a stable API of libraries you can use, which is documented here. liblog is in that list and can be included by adding the following lines to Android.mk:
LOCAL_LDLIBS := \
-llog \
The other two libraries are not part of the stable API. This essentially means that even if your code works on a particular version of Android, it may break on any later version because the API may have changed – you might want to bear this in mind.
Since these libraries are shared, all ld does is check if they actually provide the functions you're using. This question and its accepted answer have instructions for getting rid of the related error messages:
One way is to use something like:
LOCAL_LDFLAGS := -Wl,--unresolved-symbols=ignore-all
However, this will bypass all checks – so if you try to use a function that is indeed absent from the library, ld has no chance of warning you.
The cleaner, but more work-intensive approach, is to provide stub libraries. A stub library is essentially a dummy library which defines the same symbols (functions etc.) as the "real" thing but has no implementation (functions simply return without doing anything). It's enough to make the linker happy, but the libraries are not shipped and their "real" counterparts are used at runtime.
You would need to get the source code for the two libraries, which reside in the following directories: libutils and libbinders
system/core/libutils
frameworks/native/libs/binder
Copy these two dirs into your project's jni dir. Then strip the code down:
* Edit Android.mk, removing all build targets other than BUILD_SHARED_LIBRARY.
* Edit the source code files, replacing all function bodies with a simple return. It doesn't matter what you return, as long as you get the code to compile.
Eventually you will probably need to prevent the stub libraries from getting included in your .apk (I have yet to figure out how to do that).
I'm able to run the hello-jni of the samples provided in the NDK but I can't compile the hello-gl2 sample.
Could you help me? (I think is a problem linking with OpenGL)
This are the errors reported by Android Studio:
C:\AndroidstudioProjects\hello-gl2\app\src\main\jni\gl_code.cpp
Error:(39) undefined reference to `glGetError'

Error:(70) undefined reference to `glGetShaderInfoLog'
Error:(72) undefined reference to `__android_log_print'
Error:(75) undefined reference to `glDeleteShader'
...
In your Android.mk file (in the /jni folder), there should be a LOCAL_LDLIBS line. Some of the libraries that come bundled with Android need to be indicated here. Try the following
LOCAL_LDLIBS := -llog -landroid -lEGL -lGLESv1_CM
Or at least add the options -lEGL and -lGLESv1_CM. The first is the EGL library, and the second is the GLES library.
I don't know if the last one is the right version number for your project though.
Finally I used eclipse (for those that are dealing with the same problems) and with Eclipse all went fine.
I need to add to android project atom processor support. Config and build libvpx library under x86 with parameters:
./configure --disable-examples --sdk-path = '/ Android / ndk' --enable-vp8 --target = x86-android-gcc --disable-postproc
make
build success and I get a static library libvpx.a

include $ (CLEAR_VARS)

Does anyone know how to fix it? Build project under armeabi is successfully.
Trying to add flags APP_CPPFLAGS +=-std=gnu++11 and change the version of ndk
NDK_TOOLCHAIN_VERSION: = 4.8
other flags of the project:
APP_STL: = gnustl_static
APP_CPPFLAGS + =-frtti-fexceptions
APP_CFLAGS + =-Wno-error = format-security
APP_ABI: = armeabi x86
used in the construction of ndk android-ndk-r9d-linux-x86 (I tried to use android-ndk-r9d-linux-x86_64 - the same result), Ubuntu 13.10 x86_64, Eclipse 3.8.1
For me adding --extra-cflags="-U_FORTIFY_SOURCE" covered __longjmk_chk and __vsnprintf_chk
And I wrote empty __assert_fail function : extern "C" { void __assert_fail() {} }

i hope i gave the proper link in my make ,i can;t get what the error behind this,do anyone have idea about how to make exe using arm-linux-androideabi-gcc.
You have chosen a complicated way; note that with ndk-build you can build an executable much easier. For example, look at the test-libstdc++ NDK sample.
But using the bare make is also possible. You need more libraries though, when you set -nostdlib on your command line.
Add -lgcc. You may need more libs from toolchains/arm-linux-androideabi-4.6/prebuilt/windows/lib/gcc/arm-linux-androideabi/4.6.x-google to satisfy more references.
