Hi jamie,
in fact I am new in Wavecom as well. So my experience may be not very useful for others.
I was unable yet to dig deeply into this. But just renaming the “Hello World!” sample file into *.cpp was not enough. I had some C++ warnings like “TRUE is not defined” (of course, because there is “#ifndef” there in ADL headers but MINGW does not define it as well). Also at the link stage I got some other errors as result of linking C libs with C++ compiled sources.
Again, I have not tried yet to build it anyway using extern “C” {…} blocks or like. But wish to ask you: do you have any suggestions regarding C++ projects in M2M? I mean using headers from OpenAT ADL library to support C++ build (do we need manual altering?), etc.
Of course, I will check it later when time permits but any ideas will be kindly accepted to not spend a time reinventing a wheel
