Hello, I want to build an Intel x86 32 bit kernel module on Intel x86_64 machine (64 bit) running Linux. My goal is to prepare a module on a 64 bit machine, so that I can insmod this module on a 32 bit machine successfully (and don't tell me that I can build the module on a 32 bit machine. I of course know that and want to avoid it).
For that I need to build a 32 bit gcc compiler on the x86_64 machine (cross compiler). There are various tools for buildings such a cross compiler. One is Dan Kegel tool: http://kegel.com/crosstool/ Another tool is Cross-Compiled Linux From Scratch: http://cross-lfs.org/view/1.1.0/x86_64/introduction/chapter.html I want to add that "make ARCH=i686" (on the 64 bit machine) gave me errors (and also trying to passing various gcc 32 bit arch flags ). It seems to me that both these tools are more complicated then needed. Does anyone know a better way for achieving this ? for example, building binutils on the x86_64 machine (maybe with a specific 32 bit flag, and maybe also building glibc with a flag specifying the target is intel x86 machine is a must ?), and then building gcc against this libraries ?
