Question

I am trying to use a new version and libraries of the latest linphone.

Answer 1

I face same issue I have resolved issue by using Below solution:

Go to submodules/linphone/coreapi/linphonecore_jni.cc

Edit linphonecore_jni.cc file.

The change is - replace JNIEXPORT with extern "C" and remove JNICALL keyword for all function.

In your case find function setLogCollectionPath from linphonecore_jni.cc file and do above changes for setLogCollectionPath function.
