The program is in another file "exemplo.c", but the problem is in this
driver.

That's my problem! When I do 

      > gcc xdriver.c -shared -lX11 -o xdriver.so 

I get

      /usr/bin/ld: cannot find -lX11
      collect2: ld returned 1 exit status

But I have the xlibs...

ii  xlibs          4.1.0-5        X Window System client libraries
ii  xlibs-dev      4.0.3-4        X Window System client library development


Is this a problem with the PATH, I have tried to compile with

-I/usr/include

but without any luck.
