When you already changed the target, changing the size variables probably won't make a difference. Did you clear out the old contents? I think you have remaining characters in the file that are interpreted and causing the error. > a. The "MODE = sigma0" suggestion: I tried this by changing > bootstrap/server/src/Make.rules but I get an error saying: "ld: cannot > find -ll4util". The relevant part in the linker line that differs from > the default working build (with "MODE = lib") is: Wait. I meant the MODE=sigma0 for newly created programs. If you want to make bootstrap smaller, you need to remove code/features from it.
