移植speexdsp到OpenHarmony标准系统④

2024-09-09 21:33:56 浏览数 (1)

五、在OpenHarmony编译体系下增量编译Speexdsp

建议先增量编译生成三方库的动态链接库和可执行文件,验证是否成功把三方库加入OpenHarmonybian编译体系。

  • 成功编译出so和可执行文件,即成功把三方库加入到ohos编译体系。之后还要验证三方库在ohos运行,功能是否正常。功能正常才能视为移植成功。

推荐增量编译出三方库的动态链接库和测试用例,不推荐的做法是把三方库加入openharmony编译体系后全量编译出烧录ohos用的固件。

  • 第一是因为全量编译ohos对电脑的性能,特别是内存要求比较高(笔者的笔记本上的虚拟机内存给到了32G,对学生开发者来讲,编译ohos的硬件门槛还是有点高的。)增量编译对内存要求不是特别高。(笔者的8G内存二合一笔记本都可以编译出来,并且虚拟机内存只给到了4GB左右
  • 第二是因为全量编译花费时间较多(笔者完整编译出一个固件需要3个小时左右。)增量编译需要的时间相对较少(笔者大概只需要花费9分钟左右

全量编译和增量编译概念全量编译是将所有文件重新编译,重新生成解决方案就是全量编译 增量编译只对改动的文件进行编译,执行生成解决方案就是增量编译

  • ohos3.2beta1版本开始新增特性,支持64位系统的编译,默认情况下编译的都是32位系统,在编译命令中添加--target-cpu arm64即可构建64位系统,编译so和可执行文件的执行语句更改为:

在源码目录执行如下命令,进行增量编译:

代码语言:shell复制
./build.sh --product-name rk3568 --ccache --build-target=speexdsp --target-cpu arm64

加快本地编译的一些参数

编译时,适当选择添加以下的编译参数可以加快编译的过程。添加–ccache参数:原理:ccache会缓存c/c 编译的编译输出,下一次在编译输入不变的情况下,直接复用缓存的产物。 安装:快速安装:执行sudo apt-get install ccache命令。 使用:执行./build.sh --product-name 产品名 --ccache命令。 添加–fast-rebuild参数原理:编译流程主要分为:preloader->loader->gn->ninja这四个过程,在本地没有修改gn和产品配置相关文件的前提下,添加–fast-rebuild会让你直接从ninja编译开始。 使用:执行./build.sh --product-name 产品名 --fast-rebuild命令。 添加enable_notice_collection=false参数原理:省略掉收集开源软件模块的license的过程。 使用:执行./build.sh --product-name 产品名 --gn-args --enable_notice_collection=false --ccache命令。 添加–build-target参数该参数用于指定编译模块,如何找模块的名字: 相关仓下BUILD.gn中关注group、ohos_shared_library、ohos_executable等关键字。 ./build.sh --product-name 产品名 --build-target 模块名 --build-only-gn生成build.ninja,然后去该文件中查找相关模块名。 使用:执行./build.sh --product-name 产品名 --build-target ark_js_host_linux_tools_packages命令。

解决编译报错

(笔者理解移植过程肯定不会是一帆风顺的)

执行编译命令后,有部分报错

1.部分头文件缺失报错

‘speexdsp_config_types.h’ file not found

编译找不到third_party/speexdsp/include/speex目录下的speexdsp_config_types.h文件。

代码语言:shell复制
../../third_party/speexdsp/include/speex/speexdsp_types.h:122:10: fatal error: 
'speexdsp_config_types.h' file not found

解决办法:

  • speexdsp_types.h 是由linux下编译生成的,因此需要在Linux下编译整个Speexdsp源码,然后把在speexdsp原生库目录下build/include/speex目录生成的speexdsp_types.h文件拷贝到要ohos源码下的third_party/speexdsp/include/speex目录下,

2.json文件语法发生错误。

解决方法:

查看out/rk3568目录下build.log文件,检查源码/build/subsystem_config.json文件语法

笔者出现这个问题的原因是json文件语法发生错误,在subsystem_config.json文件第一行的{没有匹配},添加上去就没问题。

编译成功

解决完编译报错后,再次执行编译命令。

代码语言:shell复制
./build.sh --product-name rk3568 --ccache --build-target=speexdsp --target-cpu arm64

编译成功,终端打印信息如下:

下面只选取关键的一小部分,实际打印出来的信息有两千行左右。)

验证编译结果

编译speexdsp生成的动态链接库和测试用的可执行程序,在openharmony源码目录的out/rk3568下。

out/rk3568/speexdsp目录结构如下:

代码语言:shell复制
├── libspeexdsp_share.z.so # 动态链接库
├── testdenoise            # 测试用例 
├── testecho               # 测试用例 
├── testjitter             # 测试用例 
├── testresample           # 测试用例 
└── testresample2          # 测试用例 

六、API接口导出

在源码third_party/speexdsp目录下新建export_api文件夹。

1.在export_api目录下新建allHeads.h文件

该头文件中包含所有库对外导出的头文件。speexdsp有5个测试程序testdenoise、testecho、testjitter、testresample、testresample2。

查看这五个测试程序的源文件testdenoise.c、testecho.c、testjitter.c、testresample.c、testresample2.c。

其用到的libspeexdsp_share.z.so的头文件如下:

代码语言:c复制
#include "speex_preprocess.h"
#include "speex_echo.h"
#include "speex_jitter.h"
#include "speex_resampler.h"

2.新增allDySos目录,该目录下放置生成的动态库:

3、新增allTests目录,该目录下放置所有生成的测试文件:

4、新建自动化测试脚本export_interface.sh,如下所示:

其中cxx="0"表示根据.c文件进行导出,cxx="1"则表示根据.cpp文件进行导出(如果导出c 的三方库的api接口,使用该脚本就让cxx=1):

代码语言:c复制
#!/bin/sh
#C库
cxx="0"

mixed_api() {

    while read line
    do
        if [ $cxx != "1" -o "$4" == "1" ];then
            tmp=$line
        else
            tmp=`echo $line | sed "s/(.*$//g" | sed "s/^.*:://g"`
        fi
        res=`cat $2 |grep "$tmp" -F`
        if [ "$res" != "" ];then
            echo "$line" >> $3
        fi
    done < $1
}

remove_standard_api() {
    flag="0"
    while read line
    do
        tmp1=`echo $line |grep ".*#.*/usr/"`
        tmp2=`echo $line |grep ".*#.*[0-9].*".*""`
        if [ "$tmp1" != "" ];then
            flag="0"
        elif [ "$tmp2" != "" ];then
            flag="1"
        elif [ $flag == "1" ];then
            echo "$line" >> $2
        fi
    done < $1
}

src1="allHeads.h"
src2="allDySos"
src3="allTests"

if [ $cxx == "1" ];then
    flags_D="-DC"
    flags_DU="-DCu"
    CC=g  
else
    flags_D="-D"
    flags_DU="-Du"
    CC=gcc
fi

if [ ! -e $src1 ];then
    echo "$src1 is not exist!"
    exit 1
fi

if [ ! -e $src2 ];then
    echo "$src2 is not exist!"
    exit 1
fi

if [ ! -e $src3 ];then
    echo "$src3 is not exist!"
    exit 1
fi

rm -rf $src1.i* $src2.txt $src3.txt export_api.txt tested_api.txt

$CC -E $* $src1 -o $src1.i

if [ "$?" != "0" ];then
    exit 1
fi

remove_standard_api $src1.i $src1.i.tmp

nm $src2/* $flags_D | sort -u | grep " T " | sed "s/^.* T //g" >> $src2.txt
nm $src3/* $flags_DU | sort -u | sed "s/^.* U //g" >> $src3.txt

mixed_api $src2.txt $src1.i.tmp export_api.txt 0
mixed_api export_api.txt $src3.txt  tested_api.txt 1

rm -rf $src1.i* $src2.txt $src3.txt

执行脚本导出api接口

执行该脚本导出api接口时,需要给脚本传入编译头文件的参数。(运行此api接口导出脚本在PC端)

  • 例如./export_interface.sh -I 头文件所在路径 -D宏定义(编译所有动态库时,cflags/cflags_cc中的参数)
    • 头文件所在路径为绝对路径
    • D宏定义指的是(编译所有动态库时,cflags/cflags_cc中的参数)

笔者导出speexdsp API接口,在export_api文件夹下打开终端输入了如下命令:

代码语言:shell复制
chmod 777 export_interface.sh
./export_interface.sh -I/home/jiajiahao/Desktop/OpenHarmony/sources/third_party/speexdsp/include/speex 

结果是生成export_api.txt(导出so对外api接口)与testd_api.txt(导出测试程序所用到so对外导出api接口 )。

export_api.txt文件内容如下:
