how to build a mathgl application in ubuntu

[peter walber]

Hi,

I switched my OS from OpenSuse to ubuntu. I had many mathgl applications on OpenSuse. When I try to compile them on Ubuntu, i get the error message "fatal error: mgl2/mgl.h: file or directory not found".

I have installed mathgl with the command "sudo apt get mathgl". But eclipse does not find the include files of mathgl. To where does ubuntu install the include files ?

Did you install the mathgl development headers? These are in a separate
package in debian distributions.

In order to install the version in the repositories, use:

sudo apt install libmgl-dev

Once I do that, on my system:

$ ls /usr/include/mgl2/
abstract.h    cont.h       eval.h       mgl_cf.h     parser.h   type.h
addon.h       datac_cf.h   fit.h        mgl.fs       pde.h      vect.h
base_cf.h     data_cf.h    Fl_MathGL.h  mgl.h        plot.h     vectors.fs
base.h        datac.h      fltk.h       mgl_pas.pas  prim.h     volume.h
canvas_cf.h   data.h       font.h       mglplot.fs   qmathgl.h  window.h
canvas.h      define.h     glut.h       mpi.h        qt.h       wnd.h
canvas_wnd.h  dllexport.h  gsl.fs       opengl.h     surf.h     wx.h
config.h      evalc.h      mathgl.fs    other.h      thread.h

You should then be able to compile a simple application something like this:

===

#include <mgl2/mgl.h>

int main()
{
}
