live555 交叉编译 移植到rk3588s

下载

wget http://www.live555.com/liveMedia/public/live555-latest.tar.gz

解压

tar xf live555-latest.tar.gz

切换到源码目录

cd live

准备配置文件

在 config.armlinux 基础上改

cp config.armlinux config.armlinux-rk3588s

给 config.armlinux-rk3588s 增加写入权限

chmod u+w config.armlinux-rk3588s

编辑 config.armlinux-rk3588s，写入以下内容

生成Makefile

./genMakefiles armlinux-rk3588s

编译

make -j

安装

make install

BasicTaskScheduler.cpp 191 行处源码

#ifndef NO_STD_LIB
      if (fTriggersAwaitingHandling[i].test()) {
	fTriggersAwaitingHandling[i].clear();
#else
      if (fTriggersAwaitingHandling[i]) {
	fTriggersAwaitingHandling[i] = False;
#endif

由于进入了第一个分支导致报错，所以需要定义 NO_STD_LIB ，让其走第二个分支

-DNO_STD_LIB

编辑 config.armlinux-rk3588s，增加 -DNO_STD_LIB

COMPILE_OPTS =          $(INCLUDES) -I/home/lingke/projects/rk3588s_install_path/openssl/include -I. -O2 -DNO_STD_LIB -DSOCKLEN_T=socklen_t -DNO_SSTREAM=1 -D_LARGEFILE_SOURCE=1 -D_FILE_OFFSET_BITS=64
