        <span style="font-family:SimSun;">Hi!</span>
</p>
<p>
        <span style="font-family:SimSun;">  Recently, I need to install FLASH4.6 in a new centOS system. I don't have root authority so I didn't install the mpich, HDF5 and hypre in usr/local/....</span>
</p>
<p>
        <span style="font-family:SimSun;">I install these on another place, just like below (<strong style="font-family:SimSun;white-space:normal;">/home/hpcszb2013036/ziwei/mpich)</strong></span>
</p>
<p>
        <strong style="font-family:SimSun;"><br>

</p>
<p>
        <span style="font-family:SimSun;">[hpcszb2013036@ln4 ziwei]$ <strong>ls</strong></span>
</p>
<p>
        <span style="font-family:SimSun;"><span style="font-family:SimSun;">FLASH4.6 </span><span style="font-family:SimSun;"> <strong>hdf5</strong>  <strong>hypre </strong><strong>mpich</strong>  </span></span>
</p>
<p>
        <span style="font-family:SimSun;"><br>
</span>
</p>
<p>
        <span style="font-family:SimSun;">Also, I change the paths in Makefile.h, just like.</span>
</p>
<p>
        <span style="font-family:SimSun;"><strong>MPI_PATH   = /home/hpcszb2013036/ziwei/mpich</strong><br>
<strong>HDF4_PATH  =</strong><br>
<strong>HDF5_PATH  = /home/hpcszb2013036/ziwei/hdf5</strong><br>
<strong>HYPRE_PATH = /home/hpcszb2013036/ziwei/hypre</strong><br>
<br>
</span>
</p>
<p>
        <span style="font-family:SimSun;">However we met the warning when excuting make, just like </span>
</p>
<p>
        <span style="font-family:SimSun;"><br>
</span>
</p>
<p>
        <span style="font-family:SimSun;"><strong> </strong><strong>/usr/bin/ld: warning: libmpi.so.20, needed by /home/hpcszb2013036/ziwei/hdf5/lib/libhdf5.so, may conflict with libmpi.so.12</strong><br>
<strong>SUCCESS</strong><br>
        <p>
                why there is waring in /usr/bin/ld?
        </p>
        <p>
                <br>
        </p>
        <p>
                And when we do mpirun, it will show an error like
        </p>
        <p>
                <strong>[hpcszb2013036@ln4 object]$ mpirun -np 4 ./flash4</strong><br>
<strong>./flash4: error while loading shared libraries: libmpi.so.20: cannot open shared object file: No such file or directory</strong><br>
<strong>./flash4: error while loading shared libraries: libmpi.so.20: cannot open shared object file: No such file or directory</strong>
        </p>
        <p>
                <br>
        </p>
        <p>
                Maybe there is something wrong in my installation. Is there anyone what it is about? Thank you very much!
