linux 驅動程式 3/e書上的範例

[shihyu]

代碼: 選擇全部

#include <linux/init.h>
#include <linux/module.h>
MODULE_LICENSE("Dual BSD/GPL");

static int hello_init(void)
{
        printk(KERN_ALERT "Hello, world\n");
        return 0;
}
static void hello_exit(void)
{

        printk(KERN_ALERT "Goodbye, cruel world\n");
}

module_init(hello_init);
module_exit(hello_exit);

這是linux 驅動程式 3/e 中的範例 ....
我用gcc 直接編譯不可以編譯成功 .. 請問要編譯這是不是需要安裝什麼模組之類的???

謝謝

Kernel modules programming is a bit different from the application programming does. You can take a look at illustration on the TLDP document - http://www.tldp.org/LDP/lkmpg/2.6/html/index.html

Below is the sample Makefile required

代碼: 選擇全部

obj-m := dev_ex.o

all:
        make -C /lib/modules/$(shell uname -r)/build M=$(PWD) modules

clean:
        make -C /lib/modules/$(shell uname -r)/build M=$(PWD) clean

請加上 #include <linux/kernel.h> 試看看, 因為 printk 放上 kernel.h 裡宣告.

另, 如果你的 kernel 版本比書上的版本還舊, 有可能在後面的章節, 在使用 remap_pfn_range 時無法編譯(我的是 2.6., 較早期的 kernel 是使用 remap_page_range, 一種方式是 patch, 之前用 google 有找到過, 另一種方法是更新 kernel 版本.

Sorry, 版本變表情符號了.
是 2. 6. 8

加上#include <linux/kernel.h> 還是跟之前一樣出現一堆錯誤 , 因為我不太懂驅動程式是怎樣 , 錯誤訊息我也搞不清楚??

知道的朋友可以教一下是哪邊有問題??

謝謝

[訪客]

是用 make.

你可參考 shogun1234 回覆的內容, 在你的原始碼同一目錄下, 建立 Makefile, 然後用 make 編譯.

在後面的 Compiling Modules 有提到喔.

[shihyu]

恩~~

我把 書上程式碼 vim dev_ex.c //命名 dev_ex.c 這樣對嗎??
因為shogun1234 中的 make 是dev_ex.o 所以我命名dev_ex.c

下面是我執行步驟 及錯誤訊息

debian:~# vim dev_ex.c
debian:~# vim makefile
debian:~# make all

make: *** /lib/modules/2.6.8-2-386/build: 沒有此一檔案或目錄. Stop.
make: *** [all] Error 2

[訪客]

確定一下是否有 build 這個檔案.
它是連結到你的 kernel 原始碼所在目錄, 如果沒有的話, 你需要安裝對應於目前使用的 kernel 版本的原始碼, 如果是以 deb 方式安裝, 沒記錯的話, 壓縮檔就放在 /usr/src, 解壓縮放在 /usr/src 目錄下, 比如說是 /usr/src/kernel-source-2.6.8, 你可以在 -C 參數後直接指向 /usr/src/kernel-source-2.6.8, 一般會建議建立一個檔名 linux 連結到解壓縮後的那個目錄, -C 參數後指向 /usr/src/linux 即可.

[shihyu]

請問哪邊可以下載到原始碼???
還有kernel 版本的原始碼是要下載我系統版本一樣??
我看了 我 /usr/src/ 裡面是空的

謝謝

[shihyu]

我下載kernel-source-2.6.8 後解壓縮
把檔名改成 資料夾linux

obj-m := dev_ex.o
all:
make -C /lib/modules/$(shell uname -r)/build M=$(PWD) modules
clean:
make -C /lib/modules/$(shell uname -r)/build M=$(PWD) clean


改成

obj-m := dev_ex.o
all:
make -C /usr/src/linux

clean:
make -C /usr/src/linux

你可以用 insmod 和 rmmod 工具來測試這個模區塊. 注意只有超級用戶(root)可以加載和卸載模區塊.

[訪客]

剛下載解壓縮後是沒有 .config 這個檔案的, 在 /usr/src/linux 目錄下, 執行 make oldconfig 或 make xconfig套用目前的 config, 在 /boot 下可找到目前 kernel 使用的 config.
若用 make xconfig 須事先安裝相關的套件, 這部份可查詢 build kernel 相關文章.

M=$(shell pwd) modules 還是要加喔.

[shihyu]

我用make menuconfig ... 但裡面選項很多我用預設的
是不是要編譯書上驅程式程式碼前要先 "核心的編譯與安裝"??

是不是使用下面三個指令進行核心編譯

[root@linux linux-2.6.14.2]# make clean
# 將以前曾經進行過的 *.o 檔案刪除掉，這樣比較不會產生新舊版本的誤差！
[root@linux linux-2.6.14.2]# make bzImage
# 製作出核心檔案！這個重要！過程很長啊！而且那個是大寫的 I 喔！
[root@linux linux-2.6.14.2]# make modules
# 製作出模組相關的檔案！


之後就可以編譯書上驅動程式代碼??

obj-m := dev_ex.o

all:
make -C /usr/src/linux M=$(PWD) modules

clean:
make -C /usr/src/linux M=$(PWD) clean

變成這樣就可以make all 嗎??

謝謝

[訪客]

若你使用的是 debian 官方 kernel 版本, 僅需下載相對應之 kernel 版本的原始碼, 引用 /boot 目錄下的 config 檔案存為 .config即可, 不需另行編譯 kernel.

[訪客]

不好意思, 還有另一種不需下載原始碼的方法, 直接安裝目前使用的 kernel 所對應的 kernel-headers.

make -C /lib/modules/`uname -r`/build M=`pwd` modules

[shihyu]

我剛剛編譯出的訊息

有多出這兩檔案 Module.symvers & .tmp_versions
這樣算是編譯成功嗎??

===================================

我改用下面方式去編譯這方法是我google 搜尋到
請問我用 gcc -D__KERNEL__ -DMODULE hello.c

會出現下面一常串錯誤訊息 , 是我參數下錯嗎??還是少下??
