i agree, thats something i hope to get _fully_ working at somepoint, when i can be bothered.

Having GCC is something fairly unique however, i can't recall seeing another OS on this forum with GCC ported.

I know several people, some of which aren't on this forum, who have GCC ported. Oh well

oh well, i still think its impressive

was it hard to port?

I assume gcc only requires a working memory manager and disk access to run?

Disk access (with write support), POSIX-compatible FS functions and C library (I'm using newlib), memory management.

How do you translate the opcodes into mnemonics? Have you done the lookup-table yourself or have you some library or something? I want to implement a debugger in my kernel, but creating such a table is pain in the ... I think you know what.

Currently I've plugged in libudis86 (first hit on google) for the disassembly - and you're right in 7 source files it generates 200+K of object code.

I will be writing my own disassembler at some point, firstly to get rid of the GPL'd code and secondly to unify it with a MIPS disassembler that I have yet to write.

Thanks.
I think I'll use this for some testing and then someday write my own dis. ,though it'll take ages

Isnt't it BSD?

Mmm... I put libudis into Google instead of libudis86, came up with something about viagra

Bah, can't remember. The point is that the copyright doesn't belong to us, and I don't like that. I have to put it in its own little quarantine folder with its LICENSE file and everything. Ugh.

I can imagine.
Be aware there are bugs in Virtual PC 2007 for 64 bit Vista!

I have posted some screen already, as the search function has told me, but I'm too lazy to look it up:

here's what BlueIllusionOS (Micro kernel by the way) looks like:



Besides, is there some possibility to provide [ img ] tags with height and width attributes?

It ain't change a lot on the outside nowadays. I'm doing occasional bugfixing and am thinking of new and weird ways of doing message based ipc with variable sized messages - and a possibility to do RPC.

This is my operating system "meinOS".

This is meinOS with a virtual file system (VFS) a testfs (DEVFS) and a test program (INIT) interacting with each other.
