Hi Christophe,
I compiled the version gmsh-2.8.4-svn-20140206 with the same procedure I posted
yesterday.
Then I try to run this simple code:
#include <iostream>
#include <stdio.h>
#include "Gmsh.h"
#include "GModel.h"
int main(int argc, char **argv)
{
GmshInitialize(argc, argv);
GmshSetOption("General", "Terminal", 1.);
GmshSetOption("General", "Verbosity", 99.);
GModel *m = new GModel();
m->setFactory("Gmsh");
GVertex *v1 = m->addVertex(0, 0, 0, 0.1);
GVertex *v2 = m->addVertex(1, 0, 0, 0.1);
GVertex *v3 = m->addVertex(1, 1, 0, 0.1);
GVertex *v4 = m->addVertex(0, 1, 0, 0.1);
std::vector<GEdge*> edges;
edges.push_back(m->addLine(v1, v2));
edges.push_back(m->addLine(v2, v3));
edges.push_back(m->addLine(v3, v4));
edges.push_back(m->addLine(v4, v1));
std::vector<std::vector<GEdge*> > loop;
loop.push_back(edges);
GFace *f = m->addPlanarFace(loop);
m->mesh(2);
m->writeMSH("test.msh");
delete m;
GmshFinalize();
}
It compiles correct but when I run it the code doesn't do anything. Indeed the
content of test.msh is
$MeshFormat
2.2 0 8
$EndMeshFormat
$Nodes
0
$EndNodes
$Elements
0
$EndElements
.
The output of the debug is
Debug : Surface: 1
Debug : SVD : 1,1,0 (min=2)
Debug : Plane : (0 x + 0 y + 1 z = 0)
Debug : Normal : (0 , 0 , 1 )
Debug : t1 : (0 , 1 , 0 )
Debug : t2 : (1 , 0 , 0 )
Debug : pt : (0 , 0 , 0 )
Error : Mesh module not compiled
Is it a problem in compiling the library or I miss something when I link it to
my own code?
Thank you very much,
Marco

Hi Marco,
Indeed, it's a little incompatibility in gmsh 2.8.3 - it should be fixed with
the latest nightly snapshot. Can you give it a try?
