-

i ask if knows how create shared library accessed 2 projects. projects bootloader , application, both located @ same cortex-m0 chip , should compile , work under arm gcc , arm mdk. library quite big (about ~70k). language c.

i using extern declarations, "symdefs" file symbols+addresses (for mdk) , list of provides: symbols+addresses (for gcc) let linker know shared functionality.

the main questions how compile shared library(what options should use) , how instruct linker use library.

maybe there relative documentation creating , using shared library of compilers (for chip applications, not desktop ones).

i grateful if point me out on documentation.
