我正在尝试安装 libdvd_pkg 来播放受 DRM 保护的 DVD。dpkg-reconfigure 给出了一些线索，表明问题出在构建 libdvdcss2 上。也许我的 gcc 版本 10.3.0 有问题？还有其他方法可以在 Ubuntu 21.04 上安装 libdvdcss2 吗？
构建日志文件如下

答案1
我忘记了在某个时候我在 .bashrc 中设置了一些编译器标志。还没有调查哪个标志是问题的根源，但删除它们似乎可以解决问题。我知道这不是 -j 标志，这当然是我的第一个想法。
谢谢您的帮助，对于造成的打扰我深感抱歉。
供您参考，标志设置如下：
# export CFLAGS="-O2 -g0 -march=native -pipe -fomit-fame-pointer"
# export CXXFlAGS="$CFLAGS"
# export MAKEFLAGS="-j11"
