1997년처럼 Quake를 컴파일해 봅시다
Let's compile Quake like it's 1997
요약
이 글은 게임 Quake의 32비트 Windows 바이너리를 컴파일하는 1997년 개발 경험을 재현하는 과정을 상세히 설명합니다. Windows NT 4.0 또는 Windows 98SE가 설치된 가상 머신을 설정하고 Visual C++ 6을 설치하는 과정을 안내합니다. 이 과정에는 어셈블리 파일을 처리하고 오래된 개발 도구와의 호환성 문제를 극복하기 위한 특정 단계가 포함되어 있으며, 초기 게임 개발 관행에 대한 향수를 불러일으킵니다.

there was another article where someone bootstrapped the very first version of gcc that had the i386 backend added to it, and it turns out there was a bug in the codegen. I'll try to find it...
EDIT: Found in, infact there was a HN discussion about an article referencing the original article:
In this case there was: the reason you need to reinstall to go from uniprocessor to SMP was because NT shipped with two HALs (Hardware Abstarction Layer): one supporting just a single processor, and one supporting more than one.
The SMP one had all the code for things like CPU synchronization and interrupt routing, while the UP one did not.
If they'd packed everything into one HAL, single-processor systems would have to take the performance hit of all the synchronization code even though it wasn't necessary. Memory usage would be higher too. I expect that you probably could run the SMP HAL on a UP system (unless Microsoft put extra code in to make it not let you), but you wouldn't really want to do that, as it would be slower and require more RAM.
So it wasn't that those abstraction layers didn't exist back then. It was that abstraction layers can be expensive. This is still true today, of course, but we have the cycles and memory to spare, more or less, which was very much not the case then.
Is that accurate? I thought DJGPP only ran on and for PC compatible x86. ID had Alpha for things like running qbps and light and vis (these took for--ever to run, so the alpha SMP was really useful), but for building the actual DOS binaries, surely this was DJGPP on x86 PC?
Was DJGPP able to run on Alpha for cross compilation? I'm skeptical, but I could be wrong.
Edit: Actually it looks like you could. But did they? https://www.delorie.com/djgpp/v2faq/faq22_9.html
I have always over specified the micro-controllers a little from that point, and kept a copy of the original dev environment, luckily all my projects are now EOL as I am retired.
