Hi All,
I want to cross compile the Stunnel-5.48 for my Android AOSP (arch64)
platform using BoringSSL's 'libssl.so' and 'libcrypto.so' libraries.
I have successfully cross compiled the BoringSSL in my AOSP and both .so
file was generated for arch64 platform. Am using BoringSSL which was
delivered with Android AOSP (Android 7).
Am cross compiling using "build-android.sh" script.
But, while cross compiling the Stunnel-5.48 facing error as below:
