Compiling C/C ++ programs with STL using Android ndk

My C/C ++ program can be compiled to ZTE and run on the beacon set-top box. I thought it would be a simple task to compile it to Android, but it is far more complicated than I think.

In my program. c file and. CPP file, where. the STL string is used in the CPP file. After compilation, the STD: String library cannot be linked. The error undefined reference to 'std: basic_string is returned.

It took two days to compile the stlport library, but ended in failure. The error is as follows:

[Root @ localhost JNI] #/home/android-ndk-r6b/ndk-build

Compile the android SDK of stlport. the contents of the MK file are listed as follows. I don't know why the above error is reported. I didn't find a solution. If any hero finds the cause and compiled stlport, I hope to thank you for your help.

Stlport compilation failed. I had to find another solution, and finally found the problem. After modifying the. c file suffix to. CPP, the problem was solved.

The android. mk file of my application is as follows:

LOCAL_PATH := $(call my-dir)include $(CLEAR_VARS)LOCAL_MODULE := cloudstore_MTDLOCAL_SRC_FILES := debug.cpp hash.cpp listex.cpp md5.cpp main.cpp http_fetcher.cpp spthreadpool.cpp storex.cpp markup.cpp fusex.cppLOCAL_C_INCLUDES := /home/android-ndk-r6b/samples/fuse-android/jni/include \        /home/android-ndk-r6b/samples/sqlite-android/jni#       /home/android-ndk-r6b/platforms/android-9/arch-arm/usr/include \#       /home/android-ndk-r6b/sources/cxx-stl/gnu-libstdc++/include \#       /home/android-ndk-r6b/samples/fuse-android/jni/include $(INCDIR)LOCAL_CFLAGS := -Wall -lulockmgr -pipe -D_FILE_OFFSET_BITS=64 -D_DEBUG -DANDROID_SDK -DUSE_OPEN -DUSE_THREAD -DDEBUG -O2INCLIB := /home/android-ndk-r6b/samplesLOCAL_LDLIBS := $(INCLIB)/fuse-android/obj/local/armeabi/libfuse.a \        $(INCLIB)/libiconv/obj/local/armeabi/libiconv.a \        $(INCLIB)/sqlite-android/obj/local/armeabi/libsqlite3.ainclude $(BUILD_EXECUTABLE)

My application uses STL, So I need an application. mk file with the following content:

APP_CFLAGS += -fexceptionsAPP_STL := gnustl_static

In addition, because the library libiconv. A is required for my application, but Android does not support it, I downloaded the libiconv source code to compile it through ndk.

The android. mk file for compiling libiconv is as follows:

LOCAL_PATH:= $(call my-dir)# first lib, which will be built staticallyinclude $(CLEAR_VARS)LOCAL_MODULE := iconvLOCAL_SRC_FILES := libcharset/lib/localcharset.c lib/iconv.c lib/relocatable.cLOCAL_C_INCLUDES := include lib libcharset/includeLOCAL_CFLAGS := -Wno-multichar -D_ANDROID -DLIBDIR="c" -DBUILDING_LIBICONV -DIN_LIBRARY#LOCAL_PRELINK_MODULE := falseinclude $(BUILD_STATIC_LIBRARY)

The content of the application. mk file for compiling libiconv is as follows:

APP_MODULES := libiconv

At this point, the application compilation is complete, and you can debug it on the Android platform. I hope there will be no problems.
