-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 Hello, we are the developers of Marionnet (http://www.marionnet.org).
Sorry for asking such an obvious question, but we couldn't find any information on the official documentation: how do we cross-compile a UML kernel for a 32-bit x86 machine on an x86-64 machine? Since from the point of view of the kernel build system UML is an architecture, I couldn't find a way of specifying the actual *CPU* architecture to use: I tried to pass -m32 within the CFLAGS, but that doesn't suffice: in the end we get errors such as ake: *** [arch/um/os-Linux] Error 2 arch/um/sys-i386/setjmp.S: Assembler messages: arch/um/sys-i386/setjmp.S:27: Error: invalid instruction suffix for `pop' arch/um/sys-i386/setjmp.S:31: Error: invalid instruction suffix for `push' make[1]: *** [arch/um/sys-i386/setjmp.o] Error 1 arch/um/sys-i386/stub.S: Assembler messages: arch/um/sys-i386/stub.S:28: Error: operand type mismatch for `pop' arch/um/sys-i386/stub.S:31: Error: operand type mismatch for `pop' arch/um/sys-i386/stub.S:32: Error: operand type mismatch for `pop' arch/um/sys-i386/stub.S:33: Error: operand type mismatch for `pop' arch/um/sys-i386/stub.S:34: Error: operand type mismatch for `pop' arch/um/sys-i386/stub.S:35: Error: operand type mismatch for `pop' arch/um/sys-i386/stub.S:36: Error: operand type mismatch for `pop' arch/um/sys-i386/stub.S:42: Error: operand type mismatch for `pop' , showing that at least some data width mismatch still happens. Notice that the error is at compile time, rather than link time. I'm sure a clean solution exists, but I can't seem to find it at the moment; I suppose it should also be a frequent question...
