RISC-V平台编译 state-thread x264 ffmpeg zlog

1.state-threads

源码下来之后 

直接 make linux-debug

目录下生成了对应的.a 和 .h文件 

gcc test.c -o test -l st -L .

用网络助手测试下正常

2.x264  

默认的官网的不支持risc-v平台  去下面链接下载支持此架构的

Jiayan Qian / x264-riscv-dev · GitLab (videolan.org)






 

./configure \
        --prefix=./ubuntu \
        --enable-static \
        --enable-shared \

如上图所示生成了对应的.a文件 和头文件

3.ffmpeg

执行 脚本 

打了一大串信息
