Hi
I was wondering about the screenshot os2linuxtest.png. Is that under L4/Fiasco?
And second, who is working on that? The doscalls mentioned there, are they compiled
in a ELF file?

I have had some progress with my simple lxloader and am thinking about how to implement
the doscalls. The lxloader for now reads in a small exe file (around 200 bytes, can only handle
files up to 4 kb for now). And creates a process and runs it. Of course, because no doscalls is
available it just crashes. But the basic stuff is there.

My plans for now is to read about the ELF format and try to modify the elf-loading routines in
SDIOS to try to load shared objects and try to compile the static librarys as a shared object,
if it's possible.

Yes

And second, who is working on that?

I'm currently.

Yes. Static linking for now.

Well, I tried to contact with yor via e-mail, but no reply. So, I try to explain here.

First of all, we temporary moved our microkernel from L4Ka::Pistachio to L4/Fiasco
and reusing TUDOS/DROPS OS in many places. This is because TUDOS already has lot
of server which implement required functionality. At least we have folowing faculties:

1. Dynamic ELF loader.
2. L4VFS

This means we can start implement DosOpen and family API's. Personally I have some
problems to build correct loading of dynamic doscalls. So, now I create doscalls
implementation step by step using OS2Linux package as a base.

If you interested, pls, contact me via email and I'll discuss current situation with
development.

Actually, we very close to 0.0.2 version of release according our roadmap.
