编译linux内核报错

1、/bin/sh: 1: flex: not found

scripts/Makefile.lib:202: recipe for target 'scripts/kconfig/zconf.lex.c' failed
make[2]: *** [scripts/kconfig/zconf.lex.c] Error 127
Makefile:514: recipe for target 'silentoldconfig' failed

$ sudo apt-get install libssl-dev 

3.make menuconfig显示错误“Your display is too small to run Menuconfig!”

 

如果在终端执行 make menuconfig ,显示错误：
Your display is too small to run Menuconfig!
It must be at least 19 lines by 80 columns.
make[1]: *** [menuconfig] Error 1
make: *** [menuconfig] Error 2
表示终端窗口太小。解决办法可以是把终端窗口适当的调大（或是直接最大化）就行了。
 

3、Linux内核编译时出现fatal error: openssl/opensslv.h: No such file or directory错误的解决办法
