extract_compressed_fs.c 에서 오류 발생함.
extract_compressed_fs.c: In function `main':
extract_compressed_fs.c:66: error: `__be32' undeclared (first use in this function)
extract_compressed_fs.c:82: error: `__be64' undeclared (first use in this function)
시간이 있을때 검토해야 함.
linux/include/linux/types.h 에서
#endif __KERNEL_STRICT_NAMES
을
#ifdef CHECKER
위로 옮김.
이 경우 side effect 가 있는지 알 수 가 없슴.
compressed_loop.c
int __init init_cloop_fs(void)
void exit_cloop_fs(void)
static int __init init_cloop_fs(void)
static void __exit exit_cloop_fs(void)
edit Makefile
CFLAGS = -Wall $(COPTS) -DKERNEL -DMODULE ${INCLUDES} -march=${MARCH} \
CFLAGS = -Wall $(COPTS) -DKERNEL -DMODULE ${INCLUDES} -march=${MARCH} \
-mregparm=3 \
문제 해결됨.
cloop.ko 를 커널에 patch 하는 것도 검토 필요함.
Makefile ¶knoppix
kernel 2.6 의 경우에는 conf.vars 가 없는 것인가?
어떤 경우에 conf.vars 가 있는가? (데비안에만 있다는 설도 있슴.)
conf.vars 의 내용
VERSION = 2 PATCHLEVEL = 4 SUBLEVEL = 24 EXTRAVERSION = APPEND_TO_VERSION = -se1-686 ARCH = KPKG_ARCH = HOSTCC = HOSTCFLAGS = CROSS_COMPILE = AS = as make -p LD = ld make -p CC = cc make -p CPP = cc -E make -p AR = ar make -p NM = STRIP = OBJCOPY = OBJDUMP = MAKE = /usr/bin/make GENKSYMS = CFLAGS = AFLAGS = MODFLAGS = berry 는 cloop.mod.c 를 별도로 만들었슴.
knoppix 는 create_compressed_fs.c 에 포함되어 있슴.
knoppix 에서 conf.vars 만 없에고 사용하면 될 것 같음.
compressed_loop.c ¶knoppix 의 경우 include 파일이 보다 많이 있슴.
kernel 버전때문인 것으로 추측됨.

Be careful how you get yourself involved with persons or situations that can't bear inspection.
