[libnice] what affects the calculation of the number of candidates

[tom chen]

Hello,

The way of compilation significantly affects the number of gathered candidates. The first example is using the auto generated Makefile to compile libnice-0.1.13/examples/simple-example.c and generates 18 candidates on my PC, but the 2nd method, as mentioned in simple-example.c, just generates 3 candidates. Any idea what compilation flags are also needed as I must use the 2nd method to manually compile my applications?

1.       1. Compile using Makefile

tao at ubuntu:~/workspace/libnice-0.1.13/examples$ make simple-example

  CC       simple-example.o

  CCLD     simple-example

tao at ubuntu:~/workspace/libnice-0.1.13/examples$ ./simple-example 0 stunserver.org

2.       2. Compile manually using gcc

tao at ubuntu:~/workspace/libnice-0.1.13/examples$ gcc -o simple-example simple-example.c `pkg-config --cflags --libs nice`

tao at ubuntu:~/workspace/libnice-0.1.13/examples$ ./simple-example 0 stunserver.org
