Hi,

You may get more help from a forum for Android programmers. With that said, I can give you some hints that may help you:

1. I googled for pthreads android armv7 and found some interesting reading. Seems like -pthreads should not be added to the link command line because there's no libpthreads in Android. Check these:

https://github.com/bazelbuild/bazel/issues/7983

https://stackoverflow.com/questions/66394377/bazel-host-x86-linux-linkopts-propogating-to-target-android

2. What does ldd ./stunnel gives you?

regards,

Jose
