我通过以下方式在mint linux和mac OS机器上下载了pjsip存储库2.7.2：
svn checkout http://svn.pjsip.org/repos/pjproject/tags/2.7.2/
我尝试按照Getting Started Android中的说明操作，然后通过添加
/* Activate Android specific settings in the 'config_site_sample.h' */
#define PJ_CONFIG_ANDROID 1
#include <pj/config_site_sample.h>
然后我
$ cd /path/to/your/pjsip/dir
$ export ANDROID_NDK_ROOT=/path_to_android_ndk_dir
每次运行./configure-android时都会收到错误，如下所示：
configure-android: APP_PLATFORM not specified, using android-27
