【XR806开发板试用】编译中的几个问题以及hello跑起来

本文主要是介绍【XR806开发板试用】编译中的几个问题以及hello跑起来，希望对大家解决编程问题提供一定的参考价值，需要的开发者们随着小编来一起学习吧！

首先我们先看https://xr806.docs.aw-ol.com/
该文档部分不适应当前最新gitee

如果没有repo工具，可通过下面的git命令获取repo。

git clone https://gerrit-googlesource.lug.ustc.edu.cn/git-repo

下载代码没有使用ssh://方式过于麻烦

mkdir xr806_openharmony
cd xr806_openharmony
repo init -u https://gitee.com/openharmony-sig/manifest.git -b OpenHarmony_1.0.1_release --no-repo-verify -m devboard_xr806.xml
repo sync -c
repo forall -c 'git lfs pull'   #下载部分大容量二进制文件

编译流程

cd device/xradio/xr806/xr_skylark                               #（1）进入原生SDK目录
cp project/demo/audio_demo/gcc/deconfig .config                 #（2）复制配置文件
make menuconfig                                                 #（3）图形化界面配置
make build_clean                                                #（4）清除旧配置
make lib -j                                                     #（5）根据配置生成静态库和全局头文件
cd -                                                            #（6）返回Harmony根目录
hb set                                                          #（7）选择wifi_skylark
hb build -f                                                     #（8）编译，后续不需要重新配置

编译中遇到的问题
1.缺少SDKconfig.gni
直接导致 hb build -f 报错编译失败
解决方法
修改xr806_openharmony/device/xradio/xr806/xr_skylark/config.py
该文件的换行符 unix格式

#!/usr/bin/python3import ospwd = os.path.dirname (__file__)
f = open('{0}/.config'.format(pwd),'r')DATA = ['#XR806 config']
for line in f.readlines():if line[0] != '#' and line[0] != '\n':line = line.strip('\n')DATA.append(line)GNf = open('{0}/../liteos_m/SDKconfig.gni'.format(pwd),'w')
GNf.write('#Build by config.py DO NOT EDIT!\n\n')
GNf.write('SDK_cflags = [\n\"-mcpu=cortex-m33",\n\"-mtune=cortex-m33",\n\"-march=armv8-m.main+dsp",\n\"-mfpu=fpv5-sp-d16",\n\"-mfloat-abi=softfp",\n\"-mcmse",\n\"-mthumb",\n\"-c",\n\"-g",\n\"-fno-common",\n\"-fmessage-length=0",\n\"-fno-exceptions",\n\"-ffunction-sections",\n\"-fdata-sections",\n\"-fomit-frame-pointer",\n\"-Wall",\n\#"-Werror",\n\"-Wno-cpp",\n\"-Wpointer-arith",\n\"-Wno-error=unused-function",\n\"-MMD",\n\"-MP",\n\"-Os",\n\"-DNDEBUG",\n\"-Wno-error=stringop-truncation",\n\"-Wno-error=restrict",\n\"-includexr_config.h",\n\"-includecommon/prj_conf_opt.h",\n\"-DCONFIG_CHIP_ARCH_VER=3",\n\"-DCONFIG_ARCH_APP_CORE",\n\"-DCONFIG_CPU_CM33F",\n\
]\n\n')PROJECT = [x for i,x in enumerate(DATA) if x.find('CONFIG_PROJECT=') != -1]
if len(PROJECT) == 1:ProjectPath = PROJECT[0]ProjectPath = ProjectPath.strip('CONFIG_PROJECT=')
GNf.write('ProjectPath = {0}\n\n'.format(ProjectPath))
if ProjectPath == '"bootloader"' or ProjectPath == '"test/etf"':GNf.write('declare_args() {IsBootloader = "true"}\n')
else:GNf.write('declare_args() {IsBootloader = "false"}\n')#print (DATA)

2.hello 一直不出现
修改xr806_openharmony/device/xradio/xr806/libcopy.py
该文件的换行符是windows格式（很奇怪对吧）。

#!/usr/bin/python3import os
import jsonpwd = os.path.dirname (__file__)XTS_TEST = "disable"def filenames_filter(filename_list,Features_str,extention_name):confirm_list = []for filename in filename_list:if filename.find(Features_str) != -1:if extention_name == os.path.splitext(filename)[1]:confirm_list.append(filename)return confirm_list# whether config.json define compoent "test"?
vendorf = open('{0}/../../../vendor/xradio/xr806/config.json'.format(pwd),'r')
configData = json.load(vendorf)
subsystemsData = configData['subsystems']
for JSON_TXET in subsystemsData:ComponentJson = json.dumps(JSON_TXET)    componentPython = json.loads(ComponentJson)if componentPython["subsystem"] == "test":XTS_TEST = "enable"GNf = open('{0}/xr_skylark/ohos.mk'.format(pwd),'w')
FnList = os.listdir('{0}/xr_skylark/lib/ohos'.format(pwd))
APPlib = filenames_filter(FnList,'libapp_','.a')if XTS_TEST == "enable":TESTlib = filenames_filter(FnList,'libmodule_','.a')# if test XTS_UPgrade,KEYlib should add 'libhota.a'KEYlib = ['libwifiservice.a','libhiview_lite.a','libhilog_lite.a',\'libhievent_lite.a','libbootstrap.a','libhctest.a','libbroadcast.a']
else:TESTlib = []KEYlib = []
RTOSlib = list(set(FnList) - set(APPlib) - set(TESTlib) - set(KEYlib))GNf.write('#\n# Rules for ohos library\n#\n\n')GNf.write('OHOSSOURCE = -Wl,--whole-archive\n')
for lib in KEYlib:GNf.write('OHOSSOURCE += $(ROOT_PATH)/lib/ohos/{0}\n'.format(lib)) 
for lib in APPlib:GNf.write('OHOSSOURCE += $(ROOT_PATH)/lib/ohos/{0}\n'.format(lib))
for lib in TESTlib:GNf.write('OHOSSOURCE += $(ROOT_PATH)/lib/ohos/{0}\n'.format(lib))
GNf.write('OHOSSOURCE += -Wl,--no-whole-archive\n')
GNf.write('\n')GNf.write('OHOSSOURCE += -Wl,--start-group\n')
for lib in RTOSlib:GNf.write('OHOSSOURCE += $(ROOT_PATH)/lib/ohos/{0}\n'.format(lib))
GNf.write('OHOSSOURCE += -Wl,--end-group\n')GNf.write('#\n# end of file\n#\n\n')

win下make menuconfig问题建议用linux(能烧录哦)

目前我用了
Cygwin
msys2 以及msys2中带的msys
都是同类型错误，建议看看其他坛友是否有方法
MinGW 未试

问题2分析

文件xr806_openharmony/device/xradio/xr806/xr_skylark/ohos.mk
默认有
OHOSSOURCE = -Wl,--whole-archive
OHOSSOURCE += $(ROOT_PATH)/lib/ohos/libapp_console.a
OHOSSOURCE += -Wl,--no-whole-archive
所以编译后能跑起来
libcopy.py 未能正确运行导致
文件未被更新如：
OHOSSOURCE = -Wl,--whole-archive
OHOSSOURCE += $(ROOT_PATH)/lib/ohos/libapp_console.a
OHOSSOURCE += $(ROOT_PATH)/lib/ohos/libapp_led.a
OHOSSOURCE += $(ROOT_PATH)/lib/ohos/libapp_WlanTest.a
OHOSSOURCE += -Wl,--no-whole-archive
所以 不管你怎么改都只是 支持libapp_console 设置
可手工添加（不建议。

hello 跑起来怎么改？
https://xr806.docs.aw-ol.com/study/soft_helloword/
给的文档已经过期不适合现在最新的gitee代码

修改
xr806_openharmony/device/xradio/xr806/ohosdemo/BUILD.gn
内容：
group("ohosdemo") {deps = ["hello_demo:app_hello","LED:app_led",#"iot_peripheral:app_peripheral",#"wlan_demo:app_WlanTest",]
}

如此这般hello_demo 就能愉快的跑起来了。
