Persistence subsystem 笔记

概述

Persistence subsystem 主要的功能就是处理持久化数据，持久化数据是在重启的时候存储在头部单元内，它包括信息娱乐系统生命周期内读取和修改的所有数据。持久化数据存储在非易失性存储器中，例如硬盘驱动器或闪存

Persistence Management 的几个组件：

Persistence Client Library

Persistence Administration Service

Persistence Common Object

Persistence Health Monitor

结构框架

组件1 Persistence Client Library

主要是提供API让外部的应用可以读写持久化数据，同时提供 API 插件，允许用户使用自定义存储解决方案扩展客户库

3.1 依赖

The client library has the following dependencies

build-time library dependencies;

automotive-dlt (http://projects.genivi.org/diagnostic-log-trace/)

Persistence Common Object (https://github.com/GENIVI/persistence-common-object.git) Add "--with_database=key-value-store" to the configure step The previous default backend Itzam/C and will not supported anymore.

dbus-1

check

unit test framework for C

used when configured with "--enable-tests" Ubuntu: use Synaptic package manager Or download http://check.sourceforge.net/

tools

autotools

libtool

3.2 编译

c 复制代码

# build in SDK
eval ${OECORE_NATIVE_SYSROOT}/usr/bin/autoreconf -vi
./configure --host=aarch64-oe-linux --prefix=${OECORE_NATIVE_SYSROOT}/usr
make CFLAGS="-O2" CXXFLAGS="-O2"
make install

流程：

c 复制代码

eval ${OECORE_NATIVE_SYSROOT}/usr/bin/autoreconf -vi

问题：

c 复制代码

./configure --host=aarch64-oe-linux --prefix=${OECORE_NATIVE_SYSROOT}/usr

报错：
configure: error: Package requirements (automotive-dlt
libperscommon
dbus-1) were not met:

No package 'automotive-dlt' found

解决：

persistence-client-library-1.2.1/configure.ac

删除automotive-dlt，后续做一个假的进去

c 复制代码

./configure --host=aarch64-oe-linux --prefix=${OECORE_NATIVE_SYSROOT}/usr

No package 'libperscommon' found

解决：

pkg-config 配置文件没有办法找到

方法一: 修改 PKG_CONFIG_PATH，新增新的查找路径

c 复制代码

export PKG_CONFIG_PATH=${OECORE_NATIVE_SYSROOT}/xxx:$PKG_CONFIG_PATH

方法二：安装common的时候指定安装路径，这个路径是被 PKG_CONFIG_PATH 包含的

问题：

c 复制代码

make

报错:
fatal error: persComRct.h: No such file or directory
但是persComRct.h在下面的路径里是存在的
../../sysroots/x86_64-oesdk-linux/usr/lib/include/persComRct.h
../../sysroots/x86_64-oesdk-linux/usr/include/persComRct.h

解决:

c 复制代码

# 临时通过 make 命令指定CPPFLAGS路径
make CPPFLAGS="-I${OECORE_NATIVE_SYSROOT}/usr/include"

问题：

c 复制代码

make CPPFLAGS="-I${OECORE_NATIVE_SYSROOT}/usr/include"

报错：
fatal error: gnu/stubs-32.h: No such file or directory
7 | # include <gnu/stubs-32.h>

代码或某个依赖库试图编译 32位 代码（如 -m32 选项被启用）。

但你的 交叉编译工具链（aarch64-oe-linux）是纯 64 位环境，没有安装 32 位兼容库（multilib 支持）。

解决

c 复制代码

# 创建一个空的 stubs-32.h 文件
mkdir -p ${OECORE_NATIVE_SYSROOT}/usr/include/gnu
touch ${OECORE_NATIVE_SYSROOT}/usr/include/gnu/stubs-32.h

问题：

c 复制代码

make CFLAGS="-O2"

persistence_client_library_dbus_cmd.c:224:35: error: 'fsync' undeclared (first use in this function)
224 | list_iterate(&gOpenFdList, &fsync);

解决：

c 复制代码

先注释掉对应的行

问题：

c 复制代码

sudo make install

libtool: install: aarch64-oe-linux-ranlib /home/nio/nioworkspace/SDK_ahsoka/sysroots/aarch64-oe-linux/usr/lib/libpersistence_client_library.a
../libtool: line 1886: aarch64-oe-linux-ranlib: command not found

解决：

c 复制代码

which aarch64-oe-linux-gcc
检查 $PATH 是否包含工具链路径

export PATH=/home/nio/nioworkspace/SDK_ahsoka/sysroots/x86_64-pokysdk-linux/usr/bin/aarch64-oe-linux:$PATH

组件2 persistence-administrator

4.2 依赖

json

node-state-manager

libsystemd

4.3 编译

c 复制代码

./autogen.sh --host=aarch64-oe-linux --prefix=${OECORE_NATIVE_SYSROOT}/usr

报错

c 复制代码

configure: error: Package requirements ( json >= 0.9 ) were not met:

No package 'json' found

4.3.1 Json 包集成

git仓库：https://github.com/json-c/json-c

c 复制代码

mkdir build
cd build
../cmake-configure --prefix=${OECORE_TARGET_SYSROOT}/usr
make install

问题：

c 复制代码

make

make[1]: *** No rule to make target '/org.genivi.NodeStateManager.Consumer.xml', needed by 'NodeStateConsumer.c'. Stop.

解决:

问题:

c 复制代码

做了上述操作后报错：
Administrator/Makefile.am:80: error: comment following trailing backslash
Administrator/Makefile.am:33: warning: source file 'src/ssw_pers_admin_access_lib.c' is in a subdirectory,
Administrator/Makefile.am:33: but option 'subdir-objects' is disabled

解决:

c 复制代码

这个错误是由于 Makefile.am 中存在格式问题（反斜杠 \ 后跟注释）和未启用 subdir-objects 选项导致的

问题:

c 复制代码

make

报错：src/ssw_pers_admin_backup.c:59:1: error: parameter 'gSharedPublicRelativePath' is initialized
59 | const char* gSharedPublicRelativePath = PERS_ORG_SHARED_FOLDER_NAME PERS_ORG_PUBLIC_FOLDER_NAME_;

解决:

把下面这个注释掉,需要确保变量是全局作用域,如果这些变量出现在函数参数列表，例如

c 复制代码

void some_function(
const char* gSharedPublicRelativePath = PERS_ORG_SHARED_FOLDER_NAME PERS_ORG_PUBLIC_FOLDER_NAME_, // ❌ C 不允许参数默认值
const char* gSharedGroupRelativePath = PERS_ORG_SHARED_FOLDER_NAME PERS_ORG_GROUP_FOLDER_NAME_ "/" // ❌
) { ... }

问题:

c 复制代码

make

报错
src/ssw_pers_admin_common.c:598:5: error: format not a string literal and no format arguments [-Werror=format-security]
598 | snprintf(pchParentPath, sizeof(pchParentPath), compressFrom);

解决:

c 复制代码

//没有加 "%s"
snprintf(pchParentPath, sizeof(pchParentPath), "%s", compressFrom);

问题：

c 复制代码

make

/home/nio/nioworkspace/SDK_ahsoka/sysroots/aarch64-oe-linux/usr/include/json/config.h:8:10: fatal error: cstddef: No such file or directory
8 | #include <cstddef>

解决：

c 复制代码

cstddef是c++的库,persistence是C, 引用的也是json-c,include错了
修改：#include <josn/json.h> 改成 #include <json-c/json.h>
