Btw, you can also download pre-built UML binaries from my homepage (see signature), and this is useful even to determine what's going on (e.g. say that binary work, your one doesn't, let's compare configurations! Or a couple of months ago the answer was "let's blame this GCC", but this story is now old). It's ages I don't build a 32-bit binary on a 32-bit system. Simply replace "ARCH=um" with "ARCH=um SUBARCH=i386" in all the configuration commands. However, this presumes that libs to link/run 32-bit programs are installed. At least glibc, but I guess this is not the case for you since your kernel didn't support 32-bit binaries. ==== You say: > "compiling a uml kernel on a i386 and trying to run in resulted in 'file > not found' (shared libraries not there for the 32 bit software on the 64 > bit system)" this can mostly or totally be solved by enabling "Static linking" near where you disable TT mode (which has also other unrelated advantages). For the last error you get, try adding stderr=1 and see if something more is reported. That error is likely caused by some yet-to-be-determined simple misconfiguration (say, in the image something is missing). But I'd test first with static linking. -- Inform me of my mistakes, so I can keep imitating Homer Simpson's "Doh!".
