[Gimp-developer] How to retrieve the monitor profile from inside a plug-in

[Carmelo DrRaw <aferrero1975 gmail com>]

Dear experts,

I am trying to improve the G’MIC plug-in by adding color management of the preview area. For this, I need to 
retrieve the GIMP monitor profile from inside the plug-in code.

I have tried the following:

  GimpColorConfig* color_config = gimp_get_color_configuration();
  if(color_config)
    GimpColorProfile* dpy_profile = gimp_color_config_get_display_color_profile(color_config, NULL);

While the code compiles just fine, I get undefined symbol for get_display_profile() function at link time. 
Note that gimp_color_config_get_display_color_profile() is correctly found by the linker, so I tend to 
exclude missing libraries in the linker command, which I put here for reference:

What could I be doing wrong? Or what is the right way to retrieve the monitor profile?

Thanks in advance!
