构建VPNC采用Android NDK

问题描述

限时删除！！

我有一个基于C ++语言的Linux VPNC一个开源。下载链接：（我用VPNC-0.5.3.tar.gz）。

i have an open source for VPNC linux based on C++ language. Download link is: http://www.unix-ag.uni-kl.de/~massar/vpnc/ (i use vpnc-0.5.3.tar.gz).

所以，我要建立所有源$ C ​​$ c。使用的Andr​​oid NDK和Cygwin在Windows上.so库。

So, i want to build all source code to .so library using android ndk and cygwin on windows.

首先，当我编译源$ C ​​$ C在Cygwin上我有错误：grcypt.h没有这样的文件或目录和我解决它通过粘贴gcrypt.h文件夹JNI在Android项目。但我输入下面的问题：

First, when i compile the source code on cygwin i have the error: "grcypt.h no such file or directory" and i solved it by paste gcrypt.h file to jni folder on android project. But i enter the problem below:

$ /cygdrive/C/Working/Ke/Android/android-ndk-r8b/ndk-build
SharedLibrary  : libvpnc.so
./obj/local/armeabi/objs/vpnc/vpnc.o: In function `lifetime_ike_process':

C:\Working\Ke\Projects\Eclipse\AndroidVpnc/jni/vpnc.c:533: undefined reference to `gcry_cipher_setkey'

请给我这个问题的解决方案。

Please give me the solution for this problem.

非常感谢你。

您必须包括一个包含opt_debug，错误，xalloc，gcry_cipher_open和gcry_cipher_setkey以及图书馆。

You have to include the libraries that contains opt_debug, error, xalloc, gcry_cipher_open and gcry_cipher_setkey as well.
