UPX /src/stub/Makefile 编译 armv7

UPX /src/stub/Makefile 编译 armv7

作者: that_is_this | 来源:发表于2018-03-11 19:59 被阅读309次
    1. 编译不同平台对应的 GCC 不同，这个是编译为 arm32，对应的 gcc 是 arm-linux-androideabi-gcc，这个 GCC 的安装命令： sudo apt-get install gcc-arm-linux-androideabi

    -march 对应的是系统架构，在跟踪 UPX 源码的时候，armv7 的 so 文件对应这个

    arm.v5t-linux.shlib%.h : tc_list = arm.v5t-linux.elf default
arm.v5t-linux.shlib%.h : tc_bfdname = elf32-littlearm

tc.arm.v5t-linux.elf.gcc  = arm-linux-androideabi-gcc -march=armv5t

arm.v5t-linux.shlib%.h : $(srcdir)/src/$$T.S
    $(call tc,gcc) -c -x assembler-with-cpp $< -o tmp/$T.bin
    $(call tc,f-embed_objinfo,tmp/$T.bin)
    $(call tc,bin2h-c) tmp/$T.bin $@

    在 /src/stub/ 目录下：make 进行编译

    1. 下面是把原 Makefile 文件的 multiarch 改为 arm-linux-androideabi：
    # default multiarch-binutils
tc.default.m-ar       = arm-linux-androideabi-ar
tc.default.m-ld       = arm-linux-androideabi-ld $(if $(tc_bfdname),-b $(tc_bfdname))
tc.default.m-nm       = arm-linux-androideabi-nm $(if $(tc_bfdname),--target=$(tc_bfdname))
tc.default.m-objcopy  = arm-linux-androideabi-objcopy $(if $(tc_bfdname),-F $(tc_bfdname))
tc.default.m-objdump  = arm-linux-androideabi-objdump $(if $(tc_bfdname),-b $(tc_bfdname)) $(if $(tc_bfdarch),-m $(tc_bfdarch))
tc.default.m-readelf  = arm-linux-androideabi-readelf

# default binutils
tc.default.ld         = $(call tc,m-ld)
tc.default.nm         = $(call tc,m-nm)
tc.default.objcopy    = $(call tc,m-objcopy)
tc.default.objdump    = $(call tc,m-objdump)
tc.default.readelf    = $(call tc,m-readelf)
    1. 删除了其他平台架构的条目，只留以下的一个
    # /***********************************************************************
# // arm.v5t-linux.shlib (arm.v5t)
# ************************************************************************/

arm.v5t-linux.shlib%.h : tc_list = arm.v5t-linux.elf default
arm.v5t-linux.shlib%.h : tc_bfdname = elf32-littlearm

tc.arm.v5t-linux.elf.gcc  = arm-linux-androideabi-gcc -march=armv5t

arm.v5t-linux.shlib%.h : $(srcdir)/src/$$T.S
    $(call tc,gcc) -c -x assembler-with-cpp $< -o tmp/$T.bin
    $(call tc,f-embed_objinfo,tmp/$T.bin)
    $(call tc,bin2h-c) tmp/$T.bin $@
    1. arm64 GCC 安装

    gcc host.c -o host_32 -m32 //生成 32 位的 elf x86 文件...默认是 64 位的
    gcc -v // 查看版本信息

    arm-linux-androideabi-gcc host.c -o host_arm //生成 arm 汇编的 elf 文件

    sudo apt-get install gcc-aarch64-linux-gnu // 安装 arm64 交叉编译环境

    1. 附 arm64 Makefile 文件
