fedora 下 make 失败

[siliconrecycle]

make menuconfig 是成功的，但是接下来 make 编译的时候失败了，根据提示在 script/build.mk 第 54 行添加了 -fPIE。但是，依然报了同样的错误，我对 gcc 不是很熟悉，关于这个错误，我该怎么解决它呢？

OS: fedora36 llvm: 14.0.0 gcc: 12.1.1 g++: 12.1.1

修改 script/build.mk 中的 CFLAGS 和 LDFLAGS 似乎也没有作用。

试了下 -no-pie 还是有问题。【躺倒】

问题已经解决了。需要把 -fPIE 加在后面，这里的 makefile 的报错不是是否 shared 的意思。

我遇到了和你一样的问题，感谢你的解答，我将会在slackware下尝试它，希望它有效

管用，我的deepin20,也是这个问题，添加f-PIE后make成功
