Re: latest cvs & previous snapshot are compatible ?

The latest Fiasco which is available through CVS has the compatiblity with the previous snapshot (at 990428)?
In theory, yes. However, we don't do a lot of integrative testing with what we check into our CVS repository; so what you get from the CVS can be less stable than what you find in the snapshots, although we do aim to having a working state at all times.
I've just compiled new Fiasco (main, rmgr, sigma0), sample server (hello) and L4-Linux 2.2 on my PC. I copied them into the grub-ext2-fs-floppy (thus, grub is same with that of the previous snapshot), but I could not make them work well, even hello server does not run.
Oops, this shouldn't happen. :(
(Sorry, I can't report displayed message at present.)
The error messages are important to diagnose the problem.
I will check some couples of the combinations among old/new kernel, old/new pager, old/new server, etc. If compiled correctly, the new programs can cooporate with old programs?
Yes, this should be possible. Michael -- hohmuth@innocent.com, hohmuth@sax.de http://www.sax.de/~hohmuth/
After testing the combinations of new/old kernel & new/old server, new/old kernel can start hello server and L4-Linux 2.0, but could not start L4-Linux 2.2 server which I compiled by myself. Please ignore my previous report saying "even hello server cannot work". It seems that I used a staled floppy. Sorry! The messages displayed are following.

I'm wondering if I miscompiled L4-Linux 2.2 - I will reconsider. By the way, I want to check on 486 PC. The PC I used for compiling is Pentium machine, and the compiled kernel seems to be for Pentium and not for 486, how could I compile the kernel for 486? suzuki
