私はx86-64LinuxでRastaRing0Debuggerバージョン0.3をコンパイルしようとしています。これはLinuxカーネルモジュールです。Linux 32ビットgccインラインアセンブリを64ビットコードに変換する方法についての質問で説明したように、32ビットインラインアセンブリを64ビットアセンブリに置き換えました。、Vim正規表現を使用することにより、gccは構文エラーを発生させません。しかし、他にもいくつかのエラーが発生します。

私のコンピューターはIntelCorei7-2760QMを搭載したLenovoW520ラップトップであり、Debian GNU /LinuxWheezyを使用しています。

これらはの出力の最初の行です$ make >make_output.txt 2>&1

make -C /lib/modules/`uname -r`/build/ SUBDIRS=`pwd` modules

まず、CONFIG_X86_X32 enabled but no binutils support。しかし、私のカスタムカーネル.configでは、64ビットシステムであることは明らかです。

#
# Automatically generated file; DO NOT EDIT.
# Linux/x86_64 3.5.4 Kernel Configuration

CONFIG_64BIT=y
# CONFIG_X86_32 is not set
CONFIG_X86_64=y
CONFIG_X86=y
CONFIG_INSTRUCTION_DECODER=y
CONFIG_OUTPUT_FORMAT="elf64-x86-64"
CONFIG_ARCH_DEFCONFIG="arch/x86/configs/x86_64_defconfig"

$ make >make_output.txt 2>&1次に、出力に次の行があります。

/bin/sh: 1: nobjdump: not found

明らかに、のようなプログラムはありませんnobjdump、それはあるべきですobjdump。これはどこnから来るのでしょうか？この同じエラーは、後でld、の形式で表示されnldます。このエラーが発生する可能性があり、解決できるアイデアはありますか？

はMakefile次のとおりです。

# 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
MODULE       := rr0d.o 

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

default:
    make -C /lib/modules/`uname -r`/build/ SUBDIRS=`pwd` modules

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

mrproper:
    make clean
    rm -f *.ko

にMakefile追加-m64しましたが、出力EXTRA_FLAGSは変わりませんでした。make

出力の最後（以下の出力全体）には、上記と同じタイプのエラーがさらに3つあります。

/bin/sh: 1: nobjdump: not found

/bin/sh: 1: nobjdump: not found

/bin/sh: 1: nld: not found

明らかに、そこにnあるべきではない3つの文字があります。Linux 2.6および3.0用の「parrot」サンプルデバイスドライバーをコンパイルしようとしたときにも同じエラーが発生したため、おそらくこれはRastaRing0Debuggerとは関係ありません。

では、これらのコンパイルエラーを解決する方法はありますか？何日もグーグルで回ってもこれには役立たず、私は完全にアイデアがありません。

Debian（そしておそらくUbuntu）ユーザーはシステムの整合性をチェックできます：

debsums -s

そして壊れたパッケージを再インストールします：

binutilsをインストールし、ドライバーのパスの前後のスペースを削除してみてください。詳細については、こちらをご覧ください。

これらの2つの問題を解決した後、自分自身に答えます。最初の問題はBantharによって示され、2番目の問題は私自身によって示されます。

最初の問題は、CONFIG_X86_32とCONFIG_X86_X32が2つの異なる変数であるということです。CONFIG_X86_X32（64ビットモードの場合はx32 ABI）は、サポートNに関連する問題を解決するために設定する必要がありますbinutils。

他の問題はnobjdumpとnldです：

/bin/sh: 1: nobjdump: not found

/bin/sh: 1: nld: not found

これは、シンボリックリンクで簡単に修正できます。

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

についてはよくわかりませんが、カーネルソースディレクトリがに属していて、非特権ユーザーとして実行している場合は、nobjdump: not found取得できる場合があります。試してみてください。CONFIG_X86_X32 enabled but no binutils supportrootsudo make

もう1つの一般的な原因はCONFIG_X86_X32 enabled but no binutils support、コンパイルディレクトリ内のスペースですが、これは明らかに問題ではありません。
