| + | |||
| + | The most complex situation is when you need to embed into a minus task a binary (be it a gnuradio OOT module, an executable or a library) which depends itself from other binaries (libraries, most of the time) which need to be also embedded in the minus task. These dependency chains may be longer (eg. OOT module //A// depends on library //B//, which depends on library //C// and //D//, and library //C// depends on //D// also, as well as on library //E//). | ||
| + | |||
| + | In this situation, you need to compile everything in reverse order starting from the end of the chain (the libraries which have no custom dependencies. In the previous example, the order would be //E//, //D//, //C//, //B//, //A//). The challenge is to be able to tell following libraries (in the order of compilation) where to find previous ones includes (for compilation) and libs (for linking) | ||
