why Component Object Model (COM) is not supported on Linux?
Why Component Object Model (COM) is not supported on linux. Plz anyone give the technical perspective of this fact. I know COM is a standard developed by microsoft but after compilation what are the facts that do not let COM objects run on the Linux environment.

Back in the old days, there were two competing object models for C++, both based on RPC; COM from Microsoft and CORBA from everyone else.
Unfortunately COM still survives 20 years later, so if you want system objects on Windows, COM is still used. It's one of the oldest Technologies from Microsoft. Who'd ever guess that?
COM is inherently unsafe because it pushes responsibilities of the implementation onto the user, and if you get something wrong (which is more likely than not) it'll crash your application.
So yeah, lets port this inherently unreliable proprietary technology to an open platform with roots in more well thought out and reliable technologies.

But couldn't you say that about any programming langauge /programmer ??

But I would put money on any medium/large C/C++ application that uses COM crashing eventually solely because of it's use of COM.
Have you used it?

No, I haven't used it in anger - I have been nibbling away at learning it in a half hearted manner for some time now.
So I can't vouch for it's sability.
I however do like the progamming to an interface idea that it is based on though.

There exists lots of actively supported CORBA implementations. F.e. TAO would be nice guess. See Wikipedia for details on CORBA.
We're using CORBA for developing distributed realtime applications on multiple platforms like QNX, Linux, MS-Windows and OSX.
