Android NDK编译带STL的 C/C++ 程序

川长思鸟来 2022-08-06 17:07 283阅读 0赞

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。

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 ：

            $(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 ：

**\[plain\]** [ view plain][view plain] [copy][view plain] [print][view plain] [?][view plain]

1.  APP\_CFLAGS += -fexceptions  
2.  APP\_STL := gnustl\_static

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：

**\[html\]** [ view plain][view plain] [copy][view plain] [print][view plain] [?][view plain]

1.  LOCAL\_PATH:= $(call my-dir)  
2.    
3.  \# first lib, which will be built statically  
4.    
5.  include $(CLEAR\_VARS)  
6.    
7.  LOCAL\_MODULE := iconv  
8.  LOCAL\_SRC\_FILES := libcharset/lib/localcharset.c lib/iconv.c lib/relocatable.c  
9.    
10. LOCAL\_C\_INCLUDES := include lib libcharset/include  
11.   
12. LOCAL\_CFLAGS := -Wno-multichar -D\_ANDROID \-DLIBDIR="c" -DBUILDING\_LIBICONV -DIN\_LIBRARY  
13. \#LOCAL\_PRELINK\_MODULE := false  
14. include $(BUILD\_STATIC\_LIBRARY)

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：

**\[plain\]** [ view plain][view plain] [copy][view plain] [print][view plain] [?][view plain]

1.  APP\_MODULES := libiconv

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。
