Re: [Paparazzi-devel] math.h library

[Pascal Brisset]

Hi,

the <math.h> header is included from sw/include/std.h, itself included 
by pprz_transport.h, included by downlink.h included by ap_downlink.h

A way to look at  the includes dependencies is to use the graphs 
generated with doxygen. After installation

        sudo apt-get install doxygen graphviz

run the generation with (from the paparazzi3/ directory)

        make doxygen

and open the dox/html/ap__downlink_8h.html generated file with any navigator

--Pascal
