I tried to compile the code sample at https://www.linphone.org/snapshots/docs/liblinphone/multilang/samples/samples.html, but there was an error indicating that the "core.h" library was not found. I have installed the liblinphone.so.5 library in through apt and tried compile using command :
gcc basic-call.c -o call -llinphone
Anyobody can help why that can't working ?
