sudo apt-get install install flex

wupaul2001 · 2019-10-22 16:08:54

显示已经是最新版本

晕哥 · 2019-10-22 16:09:36

那 make clean 重来吧。

wupaul2001 · 2019-10-22 16:10:31

remove后，还是一样

wupaul2001 · 2019-10-22 16:11:21

make clean，试了N次，一样的结果

晕哥 · 2019-10-22 16:28:38

/usr/bin/gcc 是什么版本的？

wupaul2001 · 2019-10-22 16:40:31

7.4

wupaul2001 · 2019-10-22 16:41:26

现在用回buildroot的toolchain，把gcc调到6.x，正在编译

晕哥 · 2019-10-22 16:48:41

https://bugs.openwrt.org/index.php?do=details&task_id=1003

Same issue here. Can't build the toolchain on Arch with gcc 7.2.0 due to this flex bug.

上面说 gcc 7.2 有问题？

wupaul2001 · 2019-10-22 16:54:36

嗯，也测试了按commit修改，还是不行

wupaul2001 · 2019-10-22 18:03:59

修改两个文件，编译过了。遇到有朋友可以借鉴一吓

修改后再不行，请sudo apt-get install help2man

ffplay · 2019-10-22 18:46:54

还有这种操作

wlcccccc · 2019-12-29 16:48:47

我把GCC降级成4.8 就好了

淡定 · 2020-08-03 11:14:08

output/build/host-flex-2.6.4的makefile DEFS添加 -D_GNU_SOURCE

kesion · 2020-08-03 11:46:24

host-flex有什么用？

建议直接换2018.2的buildroot
