希捷powerchoice磁碟休眠功能arm打包
阿新 • • 發佈：2020-08-25
官方只提供了x86下面的包，沒有提供arm下面的包，而我們的arm機器是32位的，需要編譯一個支援armhf的二進位制檔案，這個檔案只需要一個即可，但是編譯是整套編譯的，並且我們需要選定指定的版本，關閉nvme的支援（arm的缺庫，也用不上），不帶debug資訊的
準備編譯環境
編譯環境選擇的是ubuntu 18.04 (X86),在centos下面編譯可能出現arm庫不對的情況，通常情況下，ubuntu的跨平臺編譯要好一些，並且我們的arm也是ubuntu的
安裝編譯軟體
apt-get install gcc-arm-linux-gnueabihf
支援arm的編譯環境
下載程式碼
注意要下載這個版本的，其它版本可能發生命令變化，這個無法去一個個確認，這個版本確認可以的
git clone --recursive -b Release-19.06.02 https://github.com/Seagate/openSeaChest.git
進入執行編譯命令的目錄
root@ubuntu-KVM:~/sea# cd openSeaChest/Make/gcc
root@ubuntu-KVM:~/sea/openSeaChest/Make/gcc# CC=arm-linux-gnueabihf-gcc make
修改Makefile-方便除錯編譯
clean: rm -f *.o *.a $(FILE_OUTPUT_ 改成 clean: rm -rf *.o *.a $(FILE_OUTPUT_
這個是可以讓每次編譯的時候能夠清理好環境，有個是目錄，這個需要改成r才能刪除
報錯
In file included from ../../include/platform_helper.h:22:0, from ../../src/cmds.c:21: ../../include/sg_helper.h:68:35: error: Please define one of the following to include the correct NVMe header: SEA_NVME_IOCTL_H, SEA_NVME_H, or SEA_UAPI_NVME_H These specify whether the NVMe IOCTL is in /usr/include/linux/nvme_ioctl.h, /usr/include/linux/nvme.h, or /usr/include/uapi/nvme.h #pragma GCC error "Please define one of the following to include the correct NVMe header: SEA_NVME_IOCTL_H, SEA_NVME_H, or SEA_UAPI_NVME_H\nThese specify whether the NVMe IOCTL is in /usr/include/linux/nvme_ioctl.h, /usr/include/linux/nvme.h, or /usr/include/uapi/nvme.h" ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ Makefile:99: recipe for target '../../src/cmds.o' failed
這個報錯是出現在編譯opensea-transport裡面的，我們檢查下編譯opensea-transport的Makefile
vim ./opensea-transport/Make/gcc/Makefile
#determine the proper NVMe include file. SEA_NVME_IOCTL_H, SEA_NVME_H, or SEA_UAPI_NVME_H
NVME_IOCTL_H = /usr/include/linux/nvme_ioctl.h
NVME_H = /usr/include/linux/nvme.h
UAPI_NVME_H = /usr/include/uapi/nvme.h
可以看到這個地方是引用了本地的標頭檔案，而我們的編譯環境是跨平臺編譯，肯定沒這個的arm的引用的，我們可以遮蔽掉這個nvme相關的，這個裡面是提供了遮蔽的引數的
root@ubuntu-KVM:~/sea/openSeaChest/Make/gcc# vim Makefile
#add any defines needed for tool release.
#PROJECT_DEFINES += -DDISABLE_NVME_PASSTHROUGH -DDISABLE_TCG_SUPPORT
PROJECT_DEFINES += -DDISABLE_TCG_SUPPORT
ifeq ($(UNAME),FreeBSD)
PROJECT_DEFINES += -DDISABLE_NVME_PASSTHROUGH
endif
修改為
#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
再次編譯
root@ubuntu-KVM:~/sea/openSeaChest/Make/gcc# CC=arm-linux-gnueabihf-gcc make
報錯如下
make[1]: Entering directory '/root/sea/openSeaChest/Make/gcc'
mkdir -p openseachest_exes
gcc -Wall -c -std=gnu99 -g -I../../opensea-common/include -I../../opensea-transport/include -I../../opensea-transport/include/vendor -I../../include -I../../opensea-operations/include -DDISABLE_NVME_PASSTHROUGH -DDISABLE_TCG_SUPPORT -D_DEBUG -D_DEBUG ../../utils/C/openSeaChest/openSeaChest_Firmware.c -o ../../utils/C/openSeaChest/openSeaChest_Firmware.o
make[1]: gcc: Command not found
Makefile.openSeaChest_firmware:109: recipe for target '../../utils/C/openSeaChest/openSeaChest_Firmware.o' failed
make[1]: *** [../../utils/C/openSeaChest/openSeaChest_Firmware.o] Error 127
make[1]: Leaving directory '/root/sea/openSeaChest/Make/gcc'
Makefile:210: recipe for target 'openSeaChest_Firmware' failed
可以看到上面出現了gcc，並且有openseachest_exes，這個是呼叫的另外一個makefile檔案出現的，我們檢查下makefile檔案
root@ubuntu-KVM:~/sea/openSeaChest/Make/gcc# vim Makefile.openSeaChest_firmware
可以看到寫死了兩個值
CC = gcc
STRIP = strip
我們修改為我們想編譯的平臺的
CC = arm-linux-gnueabihf-gcc
STRIP = arm-linux-gnueabihf-strip
再次編譯，順利編譯成功
root@ubuntu-KVM:~/sea/openSeaChest/Make/gcc# CC=arm-linux-gnueabihf-gcc make
這裡編譯完成的時候，預設開啟了debug，我們需要有個沒有debug資訊的版本
再次編譯
root@ubuntu-KVM:~/sea/openSeaChest/Make/gcc# CC=arm-linux-gnueabihf-gcc make release
注意我們的命令發生了變化，加上了release的字尾，這個是能夠提供兩個二進位制檔案的，一個是dbg的一個是剝離了dbg的
檢查生成的檔案
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*

root@ubuntu-KVM:~/sea/openSeaChest/Make/gcc# file openseachest_exes/openSeaChest_PowerControl

我們把openSeaChest_PowerControl拷貝到arm的機器上面執行
root@arm23:~# ./openSeaChest_PowerControl -d /dev/sdb --checkPowerMode

可以看到命令可以執行成功，並且上面也顯示的是arm的版本，剩下的具體的設定根據配置文件進行設定即可
