Description

There are a number of implicit conversion warnings in the generation of the Python interface on Mac OS X 10.14 (and alike) that should be removed by adding explicit conversions. Here a list of occurrences on Mac OS X 10.14 :

There are also some warnings at ctools level:

#2 Updated by Knödlseder Jürgen about 4 years ago

Status changed from New to In Progress
Assigned To set to Knödlseder Jürgen
% Done changed from 0 to 20

I added an explicit type conversion to the GCTAModelSpatialMultiplicative::components() method.

Furthermore, I replaced the GTypemaps.i file by the files typemap_GChatter.i and typemap_GTuple.i, including the typemaps only when needed. I also replaced the var_tuple_to_index static function in GTypemaps.i by a direct implementation in typemap_GTuple.i which removes the warnings.

There are still the following warnings

which need the implementation of a GSkyDirs container class for GSkyDir objects, and replacing

std::vector<GSkyDir> boundaries(const GSkyPixel& pixel, const int& step = 1) const;

GSkyDirs boundaries(const GSkyPixel& pixel, const int& step = 1) const;

There is also the following compilation warning:

I added a gammalib::tmpnam() function to replace the deprecated std::tmpnam() method in GVOClient.

#6 Updated by Knödlseder Jürgen about 4 years ago

Tracker changed from Bug to Action
% Done changed from 30 to 50

Except of the conversion warning in HealPix.i, all conversion warnings were successfully removed, also one that occurred in the ctbin.hpp interface.

The next step is to add a GSkyDirs class.

#7 Updated by Knödlseder Jürgen about 4 years ago

Status changed from In Progress to Pull request
% Done changed from 50 to 90

There are no more compile warnings in GammaLib and ctools.

#8 Updated by Knödlseder Jürgen about 4 years ago

Status changed from Pull request to Closed
% Done changed from 90 to 100

Merged into devel.

#9 Updated by Knödlseder Jürgen about 4 years ago

Status changed from Closed to In Progress
% Done changed from 100 to 90

I found another one after an Homebrew upgrade:

gammalib/fits_wrap.cpp:6033:53: warning: implicit conversion loses integer precision: 'long long' to 'long' [-Wshorten-64-to-32]
            PyList_SetItem(list, i, PyInt_FromLong((static_cast<long long*>(self->pixels())[i])));
                                    ~~~~~~~~~~~~~~  ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
1 warning generated.

#10 Updated by Knödlseder Jürgen about 4 years ago

Status changed from In Progress to Closed
% Done changed from 90 to 100

I also fixed this warning, code merged into devel.
