希捷powerchoice磁盘休眠功能arm打包

官方只提供了x86下面的包，没有提供arm下面的包，而我们的arm机器是32位的，需要编译一个支持armhf的二进制文件，这个文件只需要一个即可，但是编译是整套编译的，并且我们需要选定指定的版本，关闭nvme的支持（arm的缺库，也用不上），不带debug信息的

准备编译环境

编译环境选择的是ubuntu 18.04 (X86),在centos下面编译可能出现arm库不对的情况，通常情况下，ubuntu的跨平台编译要好一些，并且我们的arm也是ubuntu的

安装编译软件

apt-get install gcc-arm-linux-gnueabihf

支持arm的编译环境

下载代码

注意要下载这个版本的，其它版本可能发生命令变化，这个无法去一个个确认，这个版本确认可以的

git clone --recursive -b  Release-19.06.02 https://github.com/Seagate/openSeaChest.git

进入执行编译命令的目录

root@ubuntu-KVM:~/sea# cd openSeaChest/Make/gcc
root@ubuntu-KVM:~/sea/openSeaChest/Make/gcc# CC=arm-linux-gnueabihf-gcc make

修改Makefile-方便调试编译

clean:
        rm -f *.o *.a $(FILE_OUTPUT_
改成
clean:
        rm -rf *.o *.a $(FILE_OUTPUT_

这个是可以让每次编译的时候能够清理好环境，有个是目录，这个需要改成r才能删除

报错

In file included from ../../include/platform_helper.h:22:0,
                 from ../../src/cmds.c:21:

这个报错是出现在编译opensea-transport里面的，我们检查下编译opensea-transport的Makefile

vim ./opensea-transport/Make/gcc/Makefile

#determine the proper NVMe include file. SEA_NVME_IOCTL_H, SEA_NVME_H, or SEA_UAPI_NVME_H
NVME_IOCTL_H = /usr/include/linux/nvme_ioctl.h
NVME_H = /usr/include/linux/nvme.h
UAPI_NVME_H = /usr/include/uapi/nvme.h

可以看到这个地方是引用了本地的头文件，而我们的编译环境是跨平台编译，肯定没这个的arm的引用的，我们可以屏蔽掉这个nvme相关的，这个里面是提供了屏蔽的参数的

root@ubuntu-KVM:~/sea/openSeaChest/Make/gcc# vim Makefile
#add any defines needed for tool release.
#PROJECT_DEFINES += -DDISABLE_NVME_PASSTHROUGH -DDISABLE_TCG_SUPPORT
PROJECT_DEFINES += -DDISABLE_TCG_SUPPORT
ifeq ($(UNAME),FreeBSD)
PROJECT_DEFINES += -DDISABLE_NVME_PASSTHROUGH
endif
修改为
#add any defines needed for tool release.
PROJECT_DEFINES += -DDISABLE_NVME_PASSTHROUGH -DDISABLE_TCG_SUPPORT
#PROJECT_DEFINES += -DDISABLE_TCG_SUPPORT
ifeq ($(UNAME),FreeBSD)
PROJECT_DEFINES += -DDISABLE_NVME_PASSTHROUGH
endif

再次编译

root@ubuntu-KVM:~/sea/openSeaChest/Make/gcc#  CC=arm-linux-gnueabihf-gcc make

报错如下

make[1]: Entering directory '/root/sea/openSeaChest/Make/gcc'
mkdir -p openseachest_exes

make[1]: Leaving directory '/root/sea/openSeaChest/Make/gcc'
Makefile:210: recipe for target 'openSeaChest_Firmware' failed

可以看到上面出现了gcc，并且有openseachest_exes，这个是调用的另外一个makefile文件出现的，我们检查下makefile文件

root@ubuntu-KVM:~/sea/openSeaChest/Make/gcc# vim Makefile.openSeaChest_firmware
可以看到写死了两个值
CC = gcc

STRIP = strip

我们修改为我们想编译的平台的

CC = arm-linux-gnueabihf-gcc
STRIP = arm-linux-gnueabihf-strip

再次编译，顺利编译成功

root@ubuntu-KVM:~/sea/openSeaChest/Make/gcc#  CC=arm-linux-gnueabihf-gcc make

这里编译完成的时候，默认开启了debug，我们需要有个没有debug信息的版本

再次编译

root@ubuntu-KVM:~/sea/openSeaChest/Make/gcc#  CC=arm-linux-gnueabihf-gcc make release

注意我们的命令发生了变化，加上了release的后缀，这个是能够提供两个二进制文件的，一个是dbg的一个是剥离了dbg的

检查生成的文件

root@ubuntu-KVM:~/sea/openSeaChest/Make/gcc# ll openseachest_exes/openSeaChest_PowerControl*
-rwxr-xr-x 1 root root  822808 8月  24 17:55 openseachest_exes/openSeaChest_PowerControl*
-rwxr-xr-x 1 root root 1872988 8月  24 17:49 openseachest_exes/openSeaChest_PowerControl_dbg*

我们把openSeaChest_PowerControl拷贝到arm的机器上面执行

root@arm23:~# ./openSeaChest_PowerControl -d /dev/sdb  --checkPowerMode

可以看到命令可以执行成功，并且上面也显示的是arm的版本，剩下的具体的设置根据配置文档进行设置即可
