Well
given that you are runnig a fairly GCC all the answers is in the compiler.
$echo "#include <your_interface.h>" >gen.cpp
$g++ -c -fdump-ada-spec gen.cpp
then you will get correct mapping:
your_interface.h <=> your_interface_h.ads
See:
https://gcc.gnu.org/onlinedocs/gcc-4.9.0/gnat_ugn_unw/Running-the-binding-generator.html#Running-the-binding-generator
for more information.
To "generate" interfaces in any other way is inherently error-prone
since humans tend to miss a lot of details.
