更新librga库

测试环境：

  • LKD3576: OpenKylin 2403
  • 内核版本: 6.1
  • 开发板上安装编译工具：
sudo apt update  
sudo apt-get install python3 python3-pip python3-setuptools \  
                       python3-wheel ninja-build  
sudo pip3 install meson  
  
export PATH=/usr/local/bin:$PATH  
source ~/.bashrc

查询当前librga库版本是1.8.1_[5]

neardi@kylinos:~# strings /usr/lib/aarch64-linux-gnu/librga.so.2 | grep rga_api |grep version  
rga_api version 1.8.1_[5]

编译librga​

1. 准备工作 将 linux-rga 源代码复制到开发板的 /home/neardi 目录：

cp -r SDK/external/linux-rga /home/neardi/

2. 编译 进入linux-rga 目录，使用 meson 进行编译：

neardi@kylinos:~$ cd ~/linux-rga  
neardi@kylinos:~/linux-rga$  meson setup builddir  
neardi@kylinos:~/linux-rga$  ninja -C builddir  
neardi@kylinos:~/linux-rga$  sudo ninja -C builddir install

3. 更新库

neardi@kylinos:~/linux-rga$  sudo cp /usr/lib/aarch64-linux-gnu/librga.so.2.1.0 /usr/lib/aarch64-linux-gnu/librga.so.2.1.0.bak  
neardi@kylinos:~/linux-rga$  sudo cp /usr/local/lib/aarch64-linux-gnu/librga.so.2.1.0 /usr/lib/aarch64-linux-gnu/  
neardi@kylinos:~/linux-rga$  cd /usr/lib/aarch64-linux-gnu/  
neardi@kylinos:~/usr/lib/aarch64-linux-gnu$  sudo ln -sf librga.so.2.1.0 librga.so.2  
neardi@kylinos:~/usr/lib/aarch64-linux-gnu$  sudo ln -sf librga.so.2 librga.so  
neardi@kylinos:~/usr/lib/aarch64-linux-gnu$  sudo ldconfig

再次查询当前librga库版本是1.10.1_[10]

neardi@kylinos:~# strings /usr/lib/aarch64-linux-gnu/librga.so.2 | grep rga_api |grep version  
rga_api 1.10.1_[10]
