adb 的源码在 android 源码树中，所以只能在 Linux 下编译，而在 Linux 下编译 windows 版本的应用就需要使用交叉编译器 MinGW 了。

环境：

Ubuntu 16.04

Android 4.3 r2

>$ uname -a
Linux yuhuashi-Linux 4.4.2 #2 SMP Sun Feb 21 21:38:05 CST 2016 x86_64 x86_64 x86_64 GNU/Linux
>$

编译步骤：

1.首先安装交叉编译器。由于 LZ 已经安装过了，所以这里会提示已是最新版本。网上有的教程说要安装 mingw32，但是 LZ 从源中搜索不到相关的包，所以 LZ 安装的是 mingw-w64 这个包。

>$ sudo apt-get install mingw-w64
Reading package lists... Done
Building dependency tree       
Reading state information... Done
mingw-w64 is already the newest version (4.0.4-2).
0 upgraded, 0 newly installed, 0 to remove and 45 not upgraded.

2.接下来先不用管交叉编译器，我们进入 Android 的源码树目录，配置 adb 编译的目标平台。LZ 选的是 aosp_x86-eng，当然也可以使用 choosecombo 命令来替代 lunch 命令进行详细配置。

>$ cd android/
>$ source build/envsetup.sh 
including device/asus/deb/vendorsetup.sh
including device/asus/flo/vendorsetup.sh
including device/asus/grouper/vendorsetup.sh
including device/asus/tilapia/vendorsetup.sh
including device/generic/armv7-a-neon/vendorsetup.sh
including device/generic/mips/vendorsetup.sh
including device/generic/x86/vendorsetup.sh
including device/lge/mako/vendorsetup.sh
including device/samsung/maguro/vendorsetup.sh
including device/samsung/manta/vendorsetup.sh
including device/samsung_slsi/arndale/vendorsetup.sh
including device/samsung/toroplus/vendorsetup.sh
including device/samsung/toro/vendorsetup.sh
including device/ti/panda/vendorsetup.sh
including sdk/bash_completion/adb.bash
>$ lunch

You‘re building on Linux

Lunch menu... pick a combo:
     1. aosp_arm-eng
     2. aosp_x86-eng
     3. aosp_mips-eng
     4. vbox_x86-eng
     5. aosp_deb-userdebug
     6. aosp_flo-userdebug
     7. full_grouper-userdebug
     8. full_tilapia-userdebug
     9. mini_armv7a_neon-userdebug
     10. mini_mips-userdebug
     11. mini_x86-userdebug
     12. full_mako-userdebug
     13. full_maguro-userdebug
     14. full_manta-userdebug
     15. full_arndale-userdebug
     16. full_toroplus-userdebug
     17. full_toro-userdebug
     18. full_panda-userdebug

 2.配置好编译环境后，第一次编译的话需要先编译一下 Linux 版的 adb，不然编译的时候会有一些库找不到，以后再编译就可以跳过这一步了。

>$ make -j8 adb

3.接下来要把我们刚才安装的交叉编译器的相关路径配置到 Android 源码树的 build/core/combo/HOST_windows-x86.mk 文件中。

绿色被注释掉的是文件中原有的内容，红色的是 LZ 修改后的内容。

你们修改后的内容不一定要与 LZ 的完全一样，要自己去看看实际的路径是什么，再根据实际情况进行配置。

这段脚本计较简单，我们为什么只修改 else 里的内容呢，因为一会儿编译 windows 版本的 adb 的时候，我们要给 make 传一个叫做 USE_MINGW 的参数。

# Settings to use MinGW has a cross-compiler under Linux
ifneq ($(findstring Linux,$(UNAME)),)
ifneq ($(strip $(USE_MINGW)),)
HOST_ACP_UNAVAILABLE := true
TOOLS_EXE_SUFFIX :=
HOST_GLOBAL_CFLAGS += -DUSE_MINGW
ifneq ($(strip $(BUILD_HOST_64bit)),)
TOOLS_PREFIX := /usr/bin/amd64-mingw32msvc-
HOST_C_INCLUDES += /usr/lib/gcc/amd64-mingw32msvc/4.4.2/include
HOST_GLOBAL_LD_DIRS += -L/usr/amd64-mingw32msvc/lib
else
# TOOLS_PREFIX := /usr/bin/i586-mingw32msvc-
TOOLS_PREFIX := /usr/bin/i686-w64-mingw32-
# HOST_C_INCLUDES += /usr/lib/gcc/i586-mingw32msvc/3.4.4/include
HOST_C_INCLUDES += /usr/i686-w64-mingw32/include
# HOST_GLOBAL_LD_DIRS += -L/usr/i586-mingw32msvc/lib
HOST_GLOBAL_LD_DIRS += -L/usr/i686-w64-mingw32/lib
endif # BUILD_HOST_64bit
endif # USE_MINGW
endif # Linux

HOST_CC := $(TOOLS_PREFIX)gcc$(TOOLS_EXE_SUFFIX)
# HOST_CXX := $(TOOLS_PREFIX)g++$(TOOLS_EXE_SUFFIX)
HOST_CXX := $(TOOLS_PREFIX)g++ -static-libgcc$(TOOLS_EXE_SUFFIX)
HOST_AR := $(TOOLS_PREFIX)ar$(TOOLS_EXE_SUFFIX)

4.接下来要修改 MinGW 里面的一个头文件：/usr/share/mingw-w64/include/wincrypt.h，这个路径也要看你自己的 MinGW 路径，不一定与 LZ 的相同。

把里面 OCSP_REQUEST 宏所在位置附近的一大段宏都注释掉，LZ 猜测可能把所有的宏都注释掉也可以，不过 LZ 没有试过。

LZ 在这里被坑了一天的时间，由于 MinGW 里面的一些宏与 Android 源码树下的 external/openssl 里面的一些宏名称重复了，导致编译的时候出现各种奇怪的现象。

这一步 LZ 就不贴出代码了，别忘了编译完 windows 版本的 adb 之后，把 /usr/share/mingw-w64/include/wincrypt.h 文件还原回去。

5.经过了上面的一系列准备，现在终于可以编译我们的主角了。

>$ make -j8 USE_MINGW=y adb

host Executable: adb (out/host/windows-x86/obj/EXECUTABLES/adb_intermediates/adb.exe)

>$

如果看到最终生成了 3 个文件：AdbWinUsbApi.dll、AdbWinApi.dll 和 adb.exe，那么恭喜你编译成功了，快把这三个文件放到 windows 里面试试吧。
