code:<br>#include &lt;stdlib.h&gt;<br>#include &lt;iup.h&gt;<br><br>int 
main(int argc, char **argv)<br>{<br>&nbsp; IupOpen(&amp;argc, 
&amp;argv);<br><br>&nbsp; IupMessage("Hello World 1", "Hello world from 
IUP.");<br><br>&nbsp; IupClose();<br>&nbsp; return 
EXIT_SUCCESS;<br>}<br><br>2.<br>$gcc -I/usr/include/iup -liup 
main.c<br>/tmp/ccjjoTBI.o: In function `main':<br>main.c:(.text+0x17): 
undefined reference to `IupOpen'<br>main.c:(.text+0x2b): undefined reference to 
`IupMessage'<br>main.c:(.text+0x30): undefined reference to 
`IupClose'<br>collect2: ld returned 1 exit status<br><br>but the IupOpen is
