Hi, there,<div><br></div><div>I am trying to compile gromacs 4.0.5, 4.0.7, and 4.5.5 on a bluegene Q machine, which is brand new. After some playing around. they are all compiled and seem to run OK. However, during the compilation, there are outputs that I cannot explain and I don't know if they matter. Some of them are shown as below,</div>
<div><br></div><div>##################################################################################################################################################################################################</div><div>
<div>The NOSTRICT option (default at OPT(3)) has the potential to alter the semantics of a program. Please refer to documentation on the STRICT/NOSTRICT option for more information.</div><div><br></div><div>"clincs.c", line 1284.1: 1506-469 (I) The static function "rvec_dec" is declared or defined but never referenced.</div>

<div>They messages appear many times, but they don't pop up all together as I showed. I just select a few at different times, but I think they are representative.</div><div><br></div><div>Could anyone explain what those messages mean? Thank you very much.</div>
<div><br></div><div>In addition, I also modified the src/gmxlib/nonbonded/nb_kernel/mknb_innerloop.c. </div><div><br></div><div><div> /* mknb_assign (rinv,"frsqrtes(dble(%s))",rsq); */ </div>
<div>to</div><div> mknb_assign (rinv,"frsqrte(dble(%s))",rsq); </div></div><div><br></div><div>this modification doesn't matter, right, does it? The compiler I used is bgxlc_r, bgxlC_r, bgxlf_r, which are similar to the original IBM compilers. The difference is that they are for cross compilation.</div>
<div><br></div><div>Thank you,</div><div>Zhuyi</div>
