LDFLAGS是刚刚从一兄弟的帖子里学来的

不知道--as-needed是什么意思

怎么config.log里面 给弄成--fas-needed?

贴emerge --info

看置顶，报告问题这一步是必需的

我这边 发帖子的时候刚开始 编辑框只有一个字符宽度 所以每次我都是先写几个字 发表后再编辑

zhllg

就是这个错了
-Wl,--as-needed
-Wl,表示这个参数是传递给ld的

-Wl,--as-needed
-Wl,表示这个参数是传递给ld的

主要是参考了一些文章中:
LDFLAGS="-Wl,-O1,-Wl,--as-needed,Wl,--***"
LDFLAGS="-Wl,-O1 -Wl,--as-needed"

如上这两种设置在我这是错误的

LDFLAGS="-W1,O1,--as-need"
这样才能工作
！！-W1 只能出现一次后面还得带逗号
传递给ld的参数也用逗号分隔
！！！

nonplus

cat /etc/make.conf |grep LDFLAGS
LDFLAGS="-Wl,-O2 -Wl,--as-needed"

正常工作。。。或者你直接复制粘贴重新试试？
