Dear Support, This is Ticket #1353. I've swapped the 2 lines (6th and 7th) but nothing happened, exactly the same error! It prints a lot more things, I just copy some of them here and the dmi_scan error: -- gcc -D__KERNEL__ -DMODULE -DEXPORT_SYMTAB -fomit-frame-pointer -I. -Ikernel/include -I/usr/include -I/lib/modules/2.4.18-4GB/build/include -nostdinc -I /usr/lib/gcc-lib/i686-pc-linux-gnu/3.3/include -Wall -O2 -c kernel/busses/i2c-piix4.c -o kernel/busses/i2c-piix4.o In file included from /usr/include/asm/semaphore.h:39, from /usr/include/linux/fs.h:198, from /usr/include/linux/capability.h:17, from /usr/include/linux/binfmts.h:5, from /usr/include/linux/sched.h:8, from /usr/include/linux/mm.h:4, from /usr/include/linux/slab.h:14, from /usr/include/asm/pci.h:32, from /usr/include/linux/pci.h:610, from kernel/busses/i2c-piix4.c:34: /usr/include/asm/system.h: In function `__set_64bit_var': /usr/include/asm/system.h:184: warning: dereferencing type-punned pointer will break strict-aliasing rules /usr/include/asm/system.h:184: warning: dereferencing type-punned pointer will break strict-aliasing rules gcc -D__KERNEL__ -DMODULE -DEXPORT_SYMTAB -fomit-frame-pointer -I. -Ikernel/include -I/usr/include -I/lib/modules/2.4.18-4GB/build/include -nostdinc -I /usr/lib/gcc-lib/i686-pc-linux-gnu/3.3/include -Wall -O2 -c kernel/busses/dmi_scan.c -o kernel/busses/dmi_scan.o In file included from /usr/include/asm/semaphore.h:39, from /usr/include/linux/fs.h:198, from /usr/include/linux/capability.h:17, from /usr/include/linux/binfmts.h:5, from /usr/include/linux/sched.h:8, from /usr/include/linux/mm.h:4, from /usr/include/linux/slab.h:14, from kernel/busses/dmi_scan.c:13: /usr/include/asm/system.h: In function `__set_64bit_var': /usr/include/asm/system.h:184: warning: dereferencing type-punned pointer will break strict-aliasing rules /usr/include/asm/system.h:184: warning: dereferencing type-punned pointer will break strict-aliasing rules kernel/busses/dmi_scan.c: At top level: kernel/busses/dmi_scan.c:232: error: parse error before "config_must_be_included_before_module" kernel/busses/dmi_scan.c:232: warning: type defaults to `int' in declaration of `config_must_be_included_before_module' kernel/busses/dmi_scan.c:232: warning: data definition has no type or storage class kernel/busses/dmi_scan.c:233: error: parse error before "config_must_be_included_before_module" kernel/busses/dmi_scan.c:233: warning: type defaults to `int' in declaration of `config_must_be_included_before_module' kernel/busses/dmi_scan.c:233: warning: data definition has no type or storage class make: *** [kernel/busses/dmi_scan.o] Error 1 -- What else should I do?
