I'm new to the list (and to BSD development in general), and I'm developper
of the FreePascal project (www.freepascal.org) which is a bootstrapping
compiler, completely written in Pascal.
Currently I started preparations for a port of the linux version to FreeBSD.
FreePascal (FPC) doesn't default link to libc for some reasons, and therefore
directly calls syscalls, about 60 of them.
I started translating the syscalls this week (peeking at the linux "emulator"
code), and now I arrived at the "getdents" and readdir calls. (I want to create
a native port, the emulator already runs fine)
These are supported by the emulator, but actually are emulated (they don't
simply change parameters and do a FBSD syscall)
However when I looked into sys/syscall.h, I found out that the getdents call
seems to exist? So I have a few questions:-)
1. Is there documentation for the syscalls other than the code? I know there
are some manpages, but these seem to be outdated (e.g. the named
getdents call)
2. Can I use the getdents call to emulate the linux getdents? I use the base
functionality, not all details have to be fully the same, just the principle. And
why does the emulator not use this call?
3. If I can't use the call, the emulator code seems to call VOP_ functions. Can
I access these functions from the application?
--- not related to the other 3
4. In the rare event that I get it finished this week; The ports howto doesn't seems to
apply to bootstrapping stuff. (It assumes the apps are gcc based or created by
a gcc compiled app (like perl).
Where does such an app fit into the BSD project?
- several megs of Pascal source (entire project + sideprojects + texdocs is 25 MB
source)
- gmake makefiles.
- binary required to start the compile(either native FBSD or linux)
. (compiling the bsd version with the linux
compiler is also possible I think, if a linux binary can create an ordinary FBSD
binary)
