Hi
how you design your own "shared library"?
how you compile it and load it to memory?
thanks

I use the elf file format for every executable/shared object. The shared objects are loaded by grub as a multiboot module into memory. My kernel identifies them as shared libraries (that's in the first bytes of the elf header) and links them to a specific address (at least on x86, perhaps they will be true position independant on x86-64). When another executable elf file needs a library the library is mapped at that specific address into the address space and all necessary relocations for the executable elf file are processed.
Perhaps I will provide a callback, in case some elf file needs a not already loaded shared library and perhaps I'll reference count the shared libraries so that the memory can be freed, when they are unused. But that are future plans.

Hi bluecode
How can you map the address of a specific function in your library to the ELF executable?
thanks

This might be of help.

John.
