Are you sure you re-built the emulib? If in doubt, please "make clean" and rebuild the whole kernel. Changing the Makefile and just doing a "make" in the top-level directory is not enough because the Makefiles are probably not included in the object dependencies. Sorry for being so … [View More]

: :I think this is a problem one other user also experienced: The system :call IPC library (called ``emulation library'' for hysterical reasons) :in linux/arch/l4-i386/emulib/ has been linked to a wrong virtual :address because the magic in this directory's Makefile failed. One :possible reason is that you don't have a `cpp' in your $PATH. : :Does it help to replace "cpp" with "gcc -E" in this Makefile? : :Michael :-- I've change Makefile and Linux was compiled sucessfully.

page size assertion
by Eiji Ota 27 Nov '98

Hi all, I'm interested in this fantastic work(of course, L4). When I tried to feel it, I faced an assertion failed by assert(size == PAGE_SIZE) in space.cc(178 line). The wrong page size seemed to be passed by fpage_map in ipc_map.cc as a SUPERPAGE_SIZE, but I don't find the root cause for this trouble. Any ideas ? - Eiji Ota
