Hi, guys<div>How is it going?</div><div>when I build libmad in different platforms, i found two flags settings are different. I do not understand what those flags are used for, can any expert tell me about it?</div><div>When i build libmad , i first ./configure, and then make.</div>
<div>when I build it on 32 bits mac and 32 bits centOS,  i have flags</div><div>FPM_INTEL</div><div>ASO_ZEROCHECK</div><div><br></div><div>when I build it on 64 bits ubuntu and 64 bits centOS, I have flags</div><div> FPM_DEFAULT</div>
<div>In this case, Makefile do not have ASO_ZEROCHECK flag.</div><div><br></div><div>i try to build libmad in my own program on those systems.  i need to set the flags in my program.</div><div><br></div><div>Any ideas about this?</div>
<div><br></div><div>Another question is about : </div><div>in libmad Makefile, there are lots of optimization flags. are those flags critical and should I also brought them all to  my program?</div><div><br></div><div>Thanks!</div>
