linux内核编译

Posted 2023-05-08

编译时，提示如下错误和警告，请问是什么原因，该如何才能解决呢？
/arm2410/kernel/include/linux/mtd/nand_ids.h:55: warning: `nand_smc_info' defined but not used
make[4]: *** [nand.o] Error 1
make[4]: Leaving directory `/arm2410/kernel/drivers/mtd/nand'
make[3]: *** [first_rule] Error 2
make[3]: Leaving directory `/arm2410/kernel/drivers/mtd/nand'
make[2]: *** [_subdir_nand] Error 2

make[1]: *** [_subdir_mtd] Error 2

错误已经给你指出来了那：
nand_ids.h:55: warning: `nand_smc_info\' defined but not used
“nand_smc_info”定义了，但不能使用。

你可以到nand_ids.h去看一下是不是定义错了 参考技术A warning 那句没什么问题，就是你定义了，没用上。就怕你写成这样，你用的时候不是这样，是不是书写失误啊！！！

一、安装 OpenSSL

---

参考 【错误记录】编译 Linux 内核报错 ( fatal error: openssl/opensslv.h: No such file or directory ) 博客 , 编译内核时 , 由于没有安装 OpenSSL 报错 ;

执行

sudo apt-get install libssl-dev

命令 , 安装 OpenSSL ;

安装过程如下 :

二、安装其它依赖库

---

编译 Linux 内核还需要安装如下软件包或依赖库 :

• gcc
• libncurses5-dev
• build-essential
• kernel-package
• libssl-dev
• kernel-source-**
• libc6-dev tk8.*
• fakeroot
• bin86

执行

sudo apt-get install gcc libncurses5-dev build-essential kernel-package libssl-dev kernel-source-** libc6-dev tk8.* fakeroot bin86

命令 , 安装上述 $9$ 个依赖库 ;

三、Linux 内核编译完成

---

在 Linux 内核源码根目录中 , 执行

sudo make

命令 , 等待几小时后 , 在最后打印出如下内容 , 期间没有报错 , 即表示编译完成 ;
