NDK & GoogleTest -- Error: limits: No such file or directory

[Charles Chan]

Hello,

I am trying to get GoogleTest example working with NDK r9d on Windows with is blocked by an error when compiling the test

    >>> C:/Android/android-ndk-r9d/sources/third_party/googletest/googletest/include/gtest/gtest.h:54:18: fatal error: limits: No such file or directorycompilation terminated.
 
I have read the instructions described in \android-ndk-r9d\sources\third_party\googletest\README.NDK. Here are the steps I took:
1. Create a folder <project>\jni

2. Created jni/Android.mk:
        LOCAL_PATH := $(call my-dir)

        include $(CLEAR_VARS)
        LOCAL_MODULE := foo
        LOCAL_SRC_FILES := foo.cpp
        include $(BUILD_SHARED_LIBRARY)

        include $(CLEAR_VARS)
        LOCAL_MODULE := foo_unittest
        LOCAL_SRC_FILES := foo_unittest.cpp
        LOCAL_STATIC_LIBRARIES := googletest_main
        include $(BUILD_EXECUTABLE)

        $(call import-module,third_party/googletest)

3. Created foo.h, foo.cpp, foo_unit_test.cpp, copied from README.NDK

4. Run ndk-build and got an error:

make.exe: *** [C:/Users/cchan/Desktop/sample//obj/local/armeabi/objs/foo_unittest/foo_unittest.o] Error 1

When I search for limits.h I can see that there are multiple versions within the NDK, what do I need to do to make it work?

Thanks!
Charles

You need to use a C++ STL with your project, the default is to use the system one which is extremely basic.

Add the following to your Application.mk:

APP_STL := stlport_static

For more details, read $NDK/docs/CPLUS-PLUS-SUPPORT

Thank you! That help me moved past the roadblock and taught me something new!

(For anyone else who might be attempting to do this ...)
After pushing the shared library and executable over to the device, MAKE SURE to set the permission with the executable bit. Otherwise, you might get a permission error when executing the GoogleTest executable.
