used (GCC) does not support the '--shared' flags when the archive is build. So we
|
||||
need to create manually an archive that can be used like a shared library.
|
||||
|
||||
To do this we need to do several steps:
|
||||
1) build the sources with the PIE mode as if it were a executable without entry point.
|
||||
2) manually extract symbols defined as 'global' from the generated ELF.
|
||||
3) we create "stubs": functions that will have the same name than the wanted
|
||||
shared librairies and will call internal VHEX loader primitives with the
|
||||
librairies name, function address and size, etc....Then the loader will
|
||||
load the shared function and override the "user function (stub)" to force
|
||||
it to jump into the "real" function (trampoline)
|
||||
4) all generated stubs will be compiled and linked throught a static lib that

SHOULD be used in the user program which use the "dynamic librairy"
