The first thing is to build GCC 2… I couldn’t find any of the Linux patches for 2.0, 2.1 or 2.2.. I only tried to build 2.0 from source as targeting a.out i386 but it looks like the 2.0 files on the FSF’s site are missing files?
Anyways GCC 2.3.3 actually includes builtin support of Linux! I was able to build most of it, but just like GCC 2.5.8 for OS/2 EMX, But this time I used the gcc driver from GCC 2.6.3, which added support for Windows NT 3.5 native builds, and I now had my GCC cross compiler!
D:\aoutgcc\src>gcc2 -v -c hi.c -o hi
gcc version 2.6.3 -Linux 2.3.3
cpp2 -lang-c -v -undef -D__GNUC__=2 -Dunix -Di386 -Dlinux -D__unix__ -D__i386__ -D__linux__ -D__unix -D__i386 -D__linux hi.c C:\Temp\cca09324.i
GNU CPP version 2.3.3 (80386, BSD syntax)
cc12 C:\Temp\cca09324.i -quiet -dumpbase hi.c -version -o C:\Temp\cca09324.s
GNU C version 2.3.3 (80386, BSD syntax) compiled by GNU C version 5.1.0.
a386 -o hi C:\Temp\cca09324.s
Thankfully the prior binutils and assembler I was using in my GCC 1.40 cross compiler, still cooperated just fine, and I could happily build and link just fine.
From there it was a matter of fighting the makefiles as for some reason as make calls other makefiles they are not passing variables, so I just cheated, and changed the paths, along with editing the dependencies to finding stuff in a more sane manner. Plus all the Makefiles have include paths hard coded into the build process as expected. After fighting for a while, it linked and even better, it runs!
Linux 0.96c-71 cross compiled from windows
So yeah, using the MCC hard disk image from oldlinux.org and it boots!
Cool stuff, indeed!
As an added bonus I was also able to get 0.97 & 0.98 to compile as well!

Extra points if you can do that on AlphaNT :))
LOL with FX!32 I sure could….. Although I did a build of GCC 1.40 with Visual C++ 8.0 (aka Visual C++ 1.0 32bit), and it runs just fine. So I’d have to say it is entirely possible.
I guess I could do it on the MIPS via Qemu as a brute force proof of concept, but … it’s kind of silly..
