<div>Hi,</div>
<div> </div>
<div>My school's server has lapack and blas installed. However, I can't get it to be automatically detected by using ./configure. what is the filename that I should used? Is it liblapack.a and libblas.a? I can't find
libblas.a in the /usr/lib directory though. Is there another filename for it? I found that if I specify just the dir (/usr/lib) or liblapack.a for both the lapack and blas lib, it won't work</div>
<div> </div>
<div>Btw, can I use GotoBlas? I tried to specify libgoto.a or libgoto_northwoodp-<a href="http://r1.10.so">r1.10.so</a> and I managed to compile. However, during testing, the error msg are</div>
<div> </div>
<div>for libgoto.a : </div>

<div>That was linked for shared library. If it is for static library, the error is:</div>

<div>So can gotoblas be used?</div>
