Hi,

I am trying to read the manual of this addon (i.spec.sam in grass-addons/grass7/imagery/) from the GUI and it does not show any content.

  i.spec.sam
Traceback (most recent call last):
   File "/usr/local/grass-7.1.svn/gui/wxpython/gui_core/forms.py", line 2121, in OnPageChange
     wx.Yield()
   File "/usr/lib/python2.7/dist-packages/wx-3.0-gtk2/wx/_core.py", line 8370, in Yield
     return _core_.Yield(*args)
wx._core.PyAssertionError: C++ assertion "Assert failure" failed at ../src/common/evtloopcmn.cpp(110) in Yield(): wxYield called recursively

any help please.
Thank you,
Yann

Hi Yann,

the bug is this: the main.c is missing the corresponding part of the
next lines (this is the code of i.spec.unmix):

    module = G_define_module();
    G_add_keyword(_("imagery"));
    G_add_keyword(_("spectral unmixing"));
    module->description =
_("Performs Spectral mixture analysis of satellite/aerial images");

I suggest that you sync the parser part to i.spec.umix (different
descriptions of course).

Please also add in main.c after
#include <grass/config.h>

these lines:

#ifndef HAVE_LIBBLAS
#error GRASS is not configured with BLAS
#endif
#ifndef HAVE_LIBLAPACK
#error GRASS is not configured with LAPACK
#endif

Another small issue:

main.c:174:44: warning: '/*' within block comment [-Wcomment]
             /*b = v_get(A->m); /* dimension of
vector = matrix size = Ref.nfiles*/

thanks
Markus
