Re: [Freedos-user] re: FreeDos a good choice for me?
I'd originally posted, asking if FreeDOS is right for my application. Since I've joined the list, I've had one or two people suggest other operating systems, and a bunch of people bickering of the ownership of some wretched piece of software. No one has stepped up and suggested that FreeDOS is going to do what I need. Should I take this as a hint that I'm looking at the wrong OS? (As for ownership, as far as I can tell, the moment you post software to the net, you said goodbye to it. Copyright frequently notwithstanding. I see no way anyone can change that, so for the sake of those of us who don't care who wrote what, as long as it works, could the conversation be taken somewhere private?) --- Using Tomcat but need to do more?

It could, certainly - but in this case I think it's probably not the best choice. You've said that you almost don't need a full OS - which suggests to me that something more like a microkernel or an RTOS would better suit your needs. # Date: Wed, 19 Apr 2006 19:38:20 +0200 # From: Florian Xaver [EMAIL PROTECTED] # To: freedos-user@lists.sourceforge.net # Subject: Re: [Freedos-user] re: FreeDos a good choice for me? # # I also don't like that someone makes publicity for other operating # systems. Please don't do it ;-) Just trying to answer the question fairly; on the flip side, I've got a largish company that's using FreeDOS as the best solution for a whole bunch of stuff. That's gotta count for something right? :) --- Using Tomcat but need to do more? Need to support web services, security?

Re: [Freedos-user] re: FreeDos a good choice for me?
I tried compiling my code with Watcom. I got extremely strange behaviour - the compiler planted stack checking calls, and the stack checks were *convinced* I needed vast amounts of stack space to proceed with even the first function call out of main(). (I make very little use of the stack.) That's because OpenWatcom's default calling convention uses the stack to pass arguments. To change the default calling convention to, say, something like __cdecl, there should be a compiler option. 32bit DOS sounds right, but I read up on freeDOS-32 and it sounded like it was not ready for prime time. Does someone have a cheap/free 32 bit DOS with integrated TCP/UDP support? You don't need a 32-bit DOS kernel, but a 16-bit DOS kernel (like freedos's) and a DOS extender like cwsdpmi, dos32a, etc... -- Fall is my favorite season in Los Angeles, watching the birds change color and fall from the trees.

To change the default calling convention to, say, something like __cdecl, there should be a compiler option. No, there was something much more dire than that going on. My whole call tree doesn't go more that 8 or 10 functions deep, and it's a rare function that gets passed more than a pair of ints. Certainly no passing of structs or anything large. And no large automatic varibles or arrays, either. So maybe a few hundred words total might have been needed, but it was claiming many thousands. And it apparently calculated the maximum necessary depth at every point in the call tree, because it would trigger a stack overflow on the first call out of main - which made it impossible to figure out which function it really thought, way down the tree, needed all the space. After a half hour of banging around, I downloaded DM, and there were no stack problems. You don't need a 32-bit DOS kernel, but a 16-bit DOS kernel (like freedos's) and a DOS extender like cwsdpmi, dos32a, etc... I'm hoping I don't even need the extender. Unless waterloo TCP is ginormous, there's no reason why my code, DOS, and a packet driver shouldn't fit in 640K. --- This SF.Net email is sponsored by xPML, a groundbreaking scripting language that extends applications into web and mobile media.
