Good to know thanks, I've had more luck with the attached gcc one-liner [1] which generates fewer errors than IMA, however I'm still having problems. I've successfully run variants of this process on other projects, although I've had to switch to an older version of gcc. > > You are better off to just build all configured files as .s and cat > them together.

I have a process which "evolves" assembly code to generate variants of existing programs which have slightly different properties than the original e.g., smaller size, pass more tests, etc... see [2]. I would very much like to push busybox through this particular meat grinder as I think it could generate some interesting results. Thanks -- Eric > > Cheers, > Bernhard Footnotes: [1]
