我正在尝试为Android的pjsip构建此类文件.
按照此链接中提到的步骤进行操作后
https://trac.pjsip.org/repos/wiki/Getting-Started/Android
在完成这些步骤之前,我能够成功构建.

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

尝试构建示例pjsua2应用程序时,将引发此错误.

解决方法:

error: output/pjsua2_wrap.o: incompatible target

看到此情况后,我尝试通过删除此特定文件并允许其从脚本重新创建来解决此问题.
在此路径中删除此文件pjsua2_wrap.o后,问题已修复.

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

删除此文件后,此问题已解决.
