        <span>Hi!</span>
</p>
<p>
        <span> </span>
</p>
<p>
        <span><span> 
Recently, we want to install FLASH4.6 and related application like
mpich, HDF5, Hypre in centOS system. Before, we have successfully install it on
Ubuntu system. However, after all the intallation, we meet several problems.</span></span>
</p>
<p>
        <span> </span>
</p>
<p>
        <span><span> 
Firstly, when excuting "make" process, we meet a warning like: </span></span>
</p>
<p>
        <i><span>warning
#10006: ignoring unknown option '-fdefault-real-8'</span></i>
</p>
<p>
        <i><span>warning
#10006: ignoring unknown option '-fdefault-double-8'</span></i>
</p>
<p>
        <i><span>warning
#10157: ignoring option '-W'; argument is of wrong type </span></i>
</p>
<p>
        <span> </span>
</p>
<p>
        <span><span>  This
is not shown on the installation process for ubuntu system. However, it can
still “make” sucessfully. But when we excute mpich -np 2 ./flash4, there is
problem like: </span></span>
</p>
<p>
        <i><span>./flash4:
symbol lookup error: ./flash4: undefined symbol: for__pthread_mutex_unlock_ptr</span></i>
</p>
<p>
        <i><span>./flash4:
symbol lookup error: ./flash4: undefined symbol: for__pthread_mutex_unlock_ptr </span></i>
</p>
<p>
        <span> </span>
</p>
<p>
        <span><span>  And
the process stop immediately.</span></span>
</p>
<p>
        <span> </span>
</p>
<p>
        <span><span>  we
use CentOS 6.1, mpich3.3 hypre-2.11.1 hdf5-1.8.17. Do you know how to solve
this problem?</span></span>
</p>
<p>
        <span> </span>
</p>
<p>
        <span><span> 
Thank you very much!</span></span>
