The error <br>
<br>
Error : Singular value decomposition requires LAPACK<br>
<br>
means that your version of Gmsh (that you recompiled from source?) does not include LAPACK. This is necessary for mesh generation.<br>
<br>
Try the binary versions from the website. I also advise using a more recent version.<br>
