Compiling Under Wine
now3djp writes "Interesting article over on CodingStyle that demonstrates how I successfully eliminated wasted time maintaining an MS-Windows computer when I could build natively from my GNU computer! /. has followed other cross compilers in the past. This article is different because I used MS's own compiler! This allowed me to get on with real games porting; with only a proportional increase in compile time. Wine has really come a long way in supporting simple apps, let us hope it reaches a 1.0 soon."
It's not so interesting to me that he managed to compile using VC++ under WINE. VC++ doesn't call any of the APIs you code, it just puts machine code into the file saying you can call them if you want. It's all well and good to have VC++ compile DX9_CreateSurface() (or whatever) into a bunch of PUSHs, POPs and a JMP instruction, but that doesn't help if WINE can't actually call that function when you're testing. It makes more sense to me to use Bochs or VMWare to test your application if you're developing on multiple platforms. Anything less would be short-changing your Windows clients.
I don't believe that this is actually true. Win95 had excellent Win3.x compatibility, but developers nevertheless rushed to develop Win95 software. Why would Win3.x compatibility in OS/2 cause developers to forego native development, but not have the same effect on Win95?
I believe that what really killed OS/2 was IBM's attitude toward developers. Microsoft made it trivial to get started in Win95 development. Hell, you could go into Egghead and buy an MSDN subscription and all the tools you needed.
Compare to OS/2, where you had to apply to IBM for permission to develop, and buy an expensive development kit (at least, to officially develop).
I believe it was Jerry Pournelle who wrote of his experiences at a trade show, where he went to the MS booth, and asked what he had to do to develop for the upcoming Win95, and they handed him, on the spot, a development kit. At the IBM booth, he asked what he had to do to develop for OS/2 (a system that was already for sale, unlike Win95, which was still in beta). Did they hand him a development kit? Nope. They handed an application. If they decided he was worthy, he'd be allowed to buy a development kit.
I think that is the reason OS/2 development never took off.
Note! I'm not saying for-pay developer programs necessarily kill a platform. Apple used to have a for-pay program, but it was a joy, because of the astounding support. You sent any question off to DTS, and they would quickly have a good engineer, with full access to the source and the developers, answer it. I was having trouble with interrupt handling in a device driver, and they send me the detailed comments from the ROM source code for the interrupt handler, which explained exactly what was going on.
With Apple DTS, the feeling I had as a developer was that I was dealing with my peers at Apple, who wanted to cooperate with me to make something great. With IBM, I always felt like an insignificant pawn in whatever they were doing.
