命令：emerge qtwebengine
COMMON_FLAGS="-march=native -O2 -pipe"
MAKEOPTS="-j3"
USE="-bindist"
内存：4 GB
我尝试过删除 -pipe，并设置 -j1，还将 -jumbo-build 添加到 USE 标志，但不能同时执行这两项操作。dmesg | grep oom没有任何结果
x86_64-pc-linux-gnu-g++: fatal error: Killed signal terminated program cc1plus

答案1
/var/tmp/portage 是一个 tmpfs，对吧？在编译之前卸载它，工作数据将存储在磁盘上。
