I'm trying to port opencloth example to OpenGL 3.x. I've mostly done it to the shaders but I'm not sure of this part :

glEnableClientState(GL_VERTEX_ARRAY);
glBindBuffer(GL_ARRAY_BUFFER, vboID);
glVertexPointer(4, GL_FLOAT, 0,0);

glEnableClientState(GL_TEXTURE_COORD_ARRAY); 
glBindBuffer(GL_ARRAY_BUFFER, vboTexID);
glTexCoordPointer(2, GL_FLOAT,0, 0);

glEnableClientState(GL_NORMAL_ARRAY); 
glBindBuffer(GL_ARRAY_BUFFER, vboNormID);
glNormalPointer(GL_FLOAT,sizeof(float)*4, 0);

maybe glEnableVertexAttriArray somewhere ?

any clue ? thanx

edit : maybe something like that ?

 glEnableVertexAttribArray (2) ; // Ou glEnableVertexAttribArray (positionIndex) ;
glBindBuffer(GL_ARRAY_BUFFER, vboTexID);
glVertexAttribPointer (2, 2, GL_FLOAT, GL_FALSE, 0, 0) ;

glEnableVertexAttribArray (3) ; // Ou glEnableVertexAttribArray (positionIndex) ;
glBindBuffer(GL_ARRAY_BUFFER, vboNormID);
glVertexAttribPointer (3, 4, GL_FLOAT, GL_FALSE, sizeof (float) * 4, 0) ;
