Linux 커널 모듈을 컴파일하는 중 오류가 발생했습니다 : "CONFIG_X86_X32가 활성화되었지만 binutils가 지원되지 않습니다"및 원치 않는 "n"문자가 발생합니다.

Question

Rasta Ring0 Debugger 버전 0.3을 x86-64 Linux에서 컴파일하려고합니다. Linux 커널 모듈입니다. 나는 내 질문 How to convert Linux 32-bit gcc inline assembly to 64-bit code?에서 설명한대로 정규식 Vim을 사용하여 32 비트 인라인 어셈블리를 64 비트 어셈블리로 대체했으며 gcc는 구문 오류를 제공하지 않습니다. 하지만 몇 가지 다른 오류가 발생합니다.

내 컴퓨터는 Intel Core i7-2760QM이 장착 된 Lenovo W520 노트북이며 Debian GNU/Linux Wheezy를 사용하고 있습니다.

이 먼저 $ make >make_output.txt 2>&1

make -C /lib/modules/`uname -r`/build/ SUBDIRS=`pwd` modules 
make[1]: Entering directory `/usr/src/linux-3.5.4'

, CONFIG_X86_X32 enabled but no binutils support의 출력 첫번째 라인이다.

/bin/sh: 1: nobjdump: not found 

분명히 nobjdump 같은 그런 프로그램이이 없다 : $ make >make_output.txt 2>&1 출력이 행이,

#

둘째 :하지만 내 사용자 정의 커널 .config에 그것은 64 비트 시스템이 있다고 분명 objdump이어야합니다. 이 n의 출처는 어디입니까? 이 같은 오류는 나중에 ld과 함께 nld의 형식으로 표시됩니다. 이 오류가 발생한 모든 아이디어가 해결 될 수 있습니까? Makefile에서

# EXTRA_CFLAGS += -O2 -Wall -DLINUX_26 
EXTRA_CFLAGS += -O2 -Wall -DLINUX_26 -m64 

OBJ   := module_nux.o breakpoint.o buffering.o command.o disasmbak.o idt.o 
OBJ   += keyboard.o page.o video.o utils.o import_symb.o core_rr0d.o pci.o

obj-m  := $(MODULE) 
rr0d-objs := $(OBJ)

    rm -f *.o .*.o.cmd .*.ko.cmd *.mod.c *~ 
    rm -rf .tmp_versions 

mrproper: 
    make clean 
    rm -f *.ko 

내가 EXTRA_FLAGS에 -m64을 추가하지만이 make 출력을 변경하지 않은 :

Makefile은 다음이다.

/bin/sh: 1: nobjdump: not found 

/bin/sh: 1: nobjdump: not found 

/bin/sh: 1: nld: not found 

명확가 없어야 3 개 n 문자있다 : 출력 결국

는 (전체 출력은 아래) 전술 한 것과 동일한 유형의 세 이상의 오류가있다. 아마도 이것은 'parrot' sample device driver for Linux 2.6 and 3.0을 컴파일하려고 할 때 동일한 오류가 발생했기 때문에 Rasta Ring0 디버거와 관련이 없습니다.

그래서, 어떤 아이디어가 이러한 컴파일 오류를 해결하는 방법? 며칠 동안 인터넷 검색이 도움이되지 못했고 완전히 아이디어가 없습니다.

Answer 1

이러한 두 문제 Banthar로 나타낸 바와 같이, 먼저 자신에 의해 제 2 해결 한 후 자신에게 응답 :

이 (이미 위에서 제시된 8 개 라인을 포함) 전체 $ make >make_output.txt 2>&1 출력된다.

첫 번째 문제는 CONFIG_X86_32과 CONFIG_X86_X32이 서로 다른 두 변수입니다. binutils 지원과 관련된 문제를 해결하려면 CONFIG_X86_X32 (64 비트 모드의 경우 x32 ABI)을 N으로 설정해야합니다.

다른 문제는 nobjdump 및 nld 함께 :

/bin/sh: 1: nobjdump: not found 

/bin/sh: 1: nld: not found 

이 심볼릭 쉽게 고정 될 수

$ su 
# cd /usr/bin 
# ln -s objdump nobjdump 
# ln -s ld nld 

Answer 2

바이너리 유틸리티를 설치 및 구동의 경로 B/W 공백을 제거하려고 . 자세한 이것을 체크 아웃 : /usr/src/linux-headers-*-common/arch/x86/Makefile 에서 binutils 검사가 실패 할 경우

http://ubuntu.aspcode.net/view/635400140124705175559046/compiling-error-while-installing-realtek-rtl8111e-in-64-bit-1310-configx86x32-enabled-but-no-binutils-support

Answer 3

이 경고가 나타납니다 binutils 조립 컴파일이 성공적인되지 않은 경우

ifdef CONFIG_X86_X32 
    x32_ld_ok := $(call try-run,\ 
      /bin/echo -e '1: .quad 1b' | \ 
      $(CC) $(KBUILD_AFLAGS) -c -x assembler -o "$$TMP" - && \ 
      $(OBJCOPY) -O elf32-x86-64 "$$TMP" "$$TMPO" && \ 
      $(LD) -m elf32_x86_64 "$$TMPO" -o "$$TMP",y,n) 
     ifeq ($(x32_ld_ok),y) 
       CONFIG_X86_X32_ABI := y 
       KBUILD_AFLAGS += -DCONFIG_X86_X32_ABI 
       KBUILD_CFLAGS += -DCONFIG_X86_X32_ABI 
     else 
       $(warning CONFIG_X86_X32 enabled but no binutils support) 
     endif 
endif 

그것은 실패했습니다. 위의 수동으로 확인할 수 있습니다 명령 (실행 파일과 플래그가 다를 수 있습니다) :

CC=gcc-6 
KBUILD_AFLAGS="-D__ASSEMBLY__ -m64" 
OBJCOPY=objcopy
