Linker gives errors with the quick_start_examples

[GoogleCodeExporter]

What steps will reproduce the problem?
1. Use the compilation  command included in the quick_start_examples files 
inside the examples/doc folder

What is the expected output? What do you see instead?
I expect a successful compilation. I instead get an error list from the linker

What version of the product are you using? On what operating system?
1.7.0 RC2 under ubuntu 12.04 and 12.10

Please provide any additional information below.
I solved as follows:
instead of compiling with the suggested command which is:
gcc -o quick_start_example1 -lnfc  quick_start_example1.c

I compiled with the following command:
gcc -o quick_start_example1  quick_start_example1.c -lnfc 

I would suggest to insert this new command into the quick_start_examples files

I'm using ubuntu 12.04 and gcc 4.6.3 and that's the error I get:

gcc -o quick_start_example1 -lnfc   quick_start_example1.c 
/tmp/ccli4628.o: In function `main':

As I said if I compile with this command everything works:
gcc -o quick_start_example1   quick_start_example1.c -lnfc

Here you find a thread where there are people experiencing a problem like my 
one. Don't consider the last post, that's mine and I don't know if it solved 
the problem of the others as well:

I tried to search the web for differences between gcc 4.6 and 4.4 and I found 
this thread:
http://askubuntu.com/questions/202166/differences-in-compiling-between-gcc-4-4-a
nd-gcc-4-6

It seems that there are differences in gcc 4.6 and gcc 4.4. I didn't find 
anything official confirming this thesis.
