standard out needs to be set to binary for this to work!

setmode(fileno(stdout), O_BINARY);

Once that was in place, along with O_BINARY on the file reads for build.c, it works!

well I fixed 0.11 so now it can fully build itself on Windows. Now Qemu will boot from the floppy disk Image file generated, and that is good.

I messed with the source to 0.01, and I got it to compile. It has a mess way of detecting the filesystem of the system, and passing that to the boot.s of compiling. I tried the disk image here, but all I got was a “child 3 died with code ff00”

You ought to be able to compile it, but there isn’t a libc left to link against, and the original bash is lost. From the RELNOTES there isn’t much you could even do, as there isn’t even a ‘ls’ command. We are simply lacking the ancient libc from anything prior to version 0.12.

Don’t know why the tool to slap this together breaks on Windows, but this is how to fix it.
