Hi! As indicated in other mails, we now have support for gcc-style constructors in OsmocomBB. The way to use them is relatively easy: Simply put "__attribute__((constructor))" at the function that you want to be called during initialization. The way how this works is like this: * gcc and the linker create a table of function pointers to all the functions with that attribute * the code in compal_ramload_start.S takes care of calling lib/ctors.s:do_global_ctors() which iterates over the list and calls each constructor This concept is now used for things like prim_fbsb_init() in layer1, but I have also started to use it for board_init(). This means that board_init() no longer needs to be called from the main() function of each app. We can probably put more stuff into constructors, but we should also be careful as with gcc-4.0.2 we cannot yet indicate priorities and thus there is no explicit way to control the ordering in case of dependencies.
