<div class="moz-cite-prefix">Dear Bonan Jiang,<br>
<br>
this seems to be related to dependencies, likely METIS or MUMPS.
What versions are you using? <br>
Is the path to the header files consistent with the library
version of METIS?<br>
I would double check this first.<br>
Sharing your make.inc file might help.<br>
<br>
Let me know.<br>
