android - 在 pjsip 中成功编译 android 后尝试构建 libpjsua2.so 文件时目标不兼容

Question

我正在尝试为 Android 的 pjsip 构建 so 文件。
按照此链接中提到的步骤操作后
https://trac.pjsip.org/repos/wiki/Getting-Started/Android
在这些步骤之前，我能够成功构建。

$ ./configure-android
$ make dep && make clean && make

在尝试构建示例 pjsua2 应用程序时，它向我抛出此错误。

for dir in java; do \

done

Answer 1

error: output/pjsua2_wrap.o: incompatible target

看到这个之后，我试图通过删除这个特定文件并允许它从脚本重新创建来解决这个问题。
在此路径中删除此文件 pjsua2_wrap.o

后问题已解决

pjsip-apps/src/swig/java/output/pjsua2_wrap.o

删除该文件后，问题解决
