<div dir="ltr">Hello,<div><br></div><div>I'm having a little trouble on linking GMSH to an existing project.</div><div>Here I have two problems:</div><div><br></div><div>1 - I'm also using FMDB on this project, so there IS class conflicts (MVertex, GPoint...). As a solution, I've renamed Gmsh's class names to something else like MVertexGMSH, GPointGMSH... But I don't think that's the problem, since I've already done that and it worked before in the same project.</div>
<div><br></div><div>The problem is that I'm trying to run my project on a RedHat server, so it's a diferent computer. That brings us problem n 2:</div><div><br></div><div>2 - The linking process is returning me errors due undefined references that I've never seen before when linking Gmsh (and I've already seen many of these, but can't figure this one out...). So, the modified Gmsh compiles fine, but looks like it doesn't want to get linked with my project.</div>
<div><br></div><div>I'm running under Red Hat Enterprise Linux Server release 5.3 (Tikanga).</div><div><br></div><div>So, I hope that someone can help me out... I really can't figure this out.</div><div><br></div>
