Besides, the binary on the tape for more, a lesser less, works well enough:). I'm slowly but surely getting better at figuring out the environment - as I hit obstacles and overcome them, sometimes through my own efforts and sometimes with a little much appreciated assist. I've still got a ways to go, before I'm ready to cross compile for V7 without just doing the script kiddie method of copying and pasting stuff somebody said oughta work without any real depth of understanding what's going on under the hood. I've cross compiled linuxy stuff for arm and suchlike, but it's scripted, the binary formats standard, the header files in the right places, any chrooting set up by the scripts, etc. The concept isn't that difficult, but there are a lot of moving parts and potential complications. That said Warren's written some tools for this kinda work that are prolly simpler IIRC (aout?).
