Hi all:<br><br> I add some code in the end of md.c, in which I called a function "sqrt()", and at the start of md.c I add: #include <maths.h>.<br> As you know "sqrt()" is an often used function in the mathlib of C, however, when I complie this code, system give an error:<br>
<br><br>md.c:3011: error: `squr' undeclared (first use in this function)<br>md.c:3011: error: (Each undeclared identifier is reported only once<br>md.c:3011: error: for each function it appears in.)<br>make[3]: *** [md.o] Error 1<br>
<br>I guess I included a wrong mathlib headfile,is there anyone can tell me when Gromacs itself need to <span class="enfont"> extract a root</span> which headfile was included?<br><br>
