Android NDK编译带STL的 C/C++ 程序-优快云博客

我的这个C/C++程序，可以成功的交叉编译到中兴，烽火的机顶盒上运行，原以为编译到android应该也是一件简单的事情，但是做起来远比我想象的复杂得多。

我的程序中有 .C 文件和 .CPP 文件，其中 .CPP 文件中用到了 STL的string，编译成功后死活链接不到std::string库，提示报错 undefined reference to `std::basic_string 。

折腾了两天准备用NDK来编译 stlport库，但是以失败告终，报错如下：

[root@localhost jni]# /home/android-ndk-r6b/ndk-build

编译stlport的Android.mk文件内容如下所列，不知道为何会报上面的错误，没有找到解决办法，如果哪位大侠找到原因，成功编译了stlport，还望多多指点为谢。

LOCAL_PATH := $(call my-dir) include $(CLEAR_VARS) libstlport_path := $(call my-dir) libstlport_src_files := \ src/dll_main.cpp \ src/fstream.cpp \ src/strstream.cpp \ src/sstream.cpp \ src/ios.cpp \ src/stdio_streambuf.cpp \ src/istream.cpp \ src/ostream.cpp \ src/iostream.cpp \ src/codecvt.cpp \ src/collate.cpp \ src/ctype.cpp \ src/monetary.cpp \ src/num_get.cpp \ src/num_put.cpp \ src/num_get_float.cpp \ src/num_put_float.cpp \ src/numpunct.cpp \ src/time_facets.cpp \ src/messages.cpp \ src/locale.cpp \ src/locale_impl.cpp \ src/locale_catalog.cpp \ src/facets_byname.cpp \ src/complex.cpp \ src/complex_io.cpp \ src/complex_trig.cpp \ src/string.cpp \ src/bitset.cpp \ src/allocators.cpp \ src/c_locale.c \ src/cxa.c \ libstlport_cflags := -D_GNU_SOURCE libstlport_cppflags := -fuse-cxa-atexit libstlport_c_includes := $(libstlport_path) \ $(libstlport_path)/stlport /home/android-ndk-r6b/samples/STLport-5.2.1/jni \ /home/android-ndk-r6b/samples/STLport-5.2.1/jni/stlport \ /home/android-ndk-r6b/samples/STLport-5.2.1/jni/stlport/stl LOCAL_MODULE := stlport_static LOCAL_SRC_FILES := $(libstlport_src_files) LOCAL_CFLAGS := $(libstlport_cflags) LOCAL_CPPFLAGS := $(libstlport_cppflags) LOCAL_C_INCLUDES := $(libstlport_c_includes) LOCAL_EXPORT_C_INCLUDES := $(LOCAL_C_INCLUDES) include $(BUILD_STATIC_LIBRARY) include $(CLEAR_VARS) LOCAL_MODULE := stlport_shared LOCAL_SRC_FILES := $(libstlport_src_files) LOCAL_CFLAGS := $(libstlport_cflags) LOCAL_CPPFLAGS := $(libstlport_cppflags) LOCAL_C_INCLUDES := $(libstlport_c_includes) LOCAL_EXPORT_C_INCLUDES := $(LOCAL_C_INCLUDES) include $(BUILD_SHARED_LIBRARY)
stlport编译失败，只能在另外想办法了，最后终于找到了问题所在，把 .C 文件后缀修改为 .CPP后问题得到解决。

我应用程序的 Android.mk文件如下：

LOCAL_PATH := $(call my-dir) include $(CLEAR_VARS) LOCAL_MODULE := cloudstore_MTD LOCAL_SRC_FILES := debug.cpp hash.cpp listex.cpp md5.cpp main.cpp http_fetcher.cpp spthreadpool.cpp storex.cpp markup.cpp fusex.cpp LOCAL_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 -O2 INCLIB := /home/android-ndk-r6b/samples LOCAL_LDLIBS := $(INCLIB)/fuse-android/obj/local/armeabi/libfuse.a \ $(INCLIB)/libiconv/obj/local/armeabi/libiconv.a \ $(INCLIB)/sqlite-android/obj/local/armeabi/libsqlite3.a include $(BUILD_EXECUTABLE)

我应用程序用到了STL，所以还得需要一个 Application.mk 文件，内容如下：

APP_CFLAGS += -fexceptions APP_STL := gnustl_static

另外，由于我的应用程序还需要用到 libiconv.a这个库，但是android并没有这方面的支持，所以我下载了libiconv的源码来通过NDK编译。

编译libiconv的 Android.mk文件内容如下：

LOCAL_PATH:= $(call my-dir) # first lib, which will be built statically include $(CLEAR_VARS) LOCAL_MODULE := iconv LOCAL_SRC_FILES := libcharset/lib/localcharset.c lib/iconv.c lib/relocatable.c LOCAL_C_INCLUDES := include lib libcharset/include LOCAL_CFLAGS := -Wno-multichar -D_ANDROID -DLIBDIR="c" -DBUILDING_LIBICONV -DIN_LIBRARY #LOCAL_PRELINK_MODULE := false include $(BUILD_STATIC_LIBRARY)

编译libiconv的Application.mk文件内容如下：

APP_MODULES := libiconv
至此，应用程序编译完毕，下来在Android平台上慢慢调试吧，希望不要有问题。
