        在x86上做出來了，但是在ARM上卻出現了很多問題，有核心程式碼準備的問題，有模組程式碼問題，也有Makefile的問題。看似不起眼的角色，出了問題也很糾結。

第一種：核心程式碼沒有準備好

[[email protected] module]# make make -C /opt/kangear/kernel/linux-2.6.32.2 M=/root/桌面/kangear/module modulesmake[1]: Entering directory `/opt/kangear/kernel/linux-2.6.32.2'  ERROR: Kernel configuration is invalid.         include/linux/autoconf.h or include/config/auto.conf are missing.         Run 'make oldconfig && make prepare' on kernel src to fix it.  WARNING: Symbol version dump /opt/kangear/kernel/linux-2.6.32.2/Module.symvers           is missing; modules will have no dependencies and modversions.  Building modules, stage 2./opt/kangear/kernel/linux-2.6.32.2/scripts/Makefile.modpost:42: include/config/auto.conf: 沒有那個檔案或目錄make[2]: *** 沒有規則可以建立目標“include/config/auto.conf”。 停止。make[1]: *** [modules] 錯誤 2make[1]: Leaving directory `/opt/kangear/kernel/linux-2.6.32.2'make: *** [all] 錯誤 2[
 
[email protected] module]# 

        其實看實質就是找不到auto.conf，這個其實已經有了，就是.config，但是如果不想手動來拷貝可以假裝make zImage（如下），這裡就可以了，完整的編譯一個核心只為了這個一個配置檔案，也太浪費了。

[[email protected] module]# makemake -C /opt/kangear/kernel/linux-2.6.32.2 M=/root/桌面/kangear/module modulesmake[1]: Entering directory `/opt/kangear/kernel/linux-2.6.32.2'  WARNING: Symbol version dump /opt/kangear/kernel/linux-2.6.32.2/Module.symvers           is missing; modules will have no dependencies and modversions.  CC [M]  /root/桌面/kangear/module/hello.o  Building modules, stage 2.  MODPOST 1 modulesWARNING: modpost: missing MODULE_LICENSE() in /root/桌面/kangear/module/hello.osee include/linux/module.h for more information  CC      /root/桌面/kangear/module/hello.mod.o  LD [M]  /root/桌面/kangear/module/hello.komake[1]: Leaving directory `/opt/kangear/kernel/linux-2.6.32.2'[[email protected] module]# lshello.c   hello.mod.c  hello.o   modules.order   paramhello.ko  hello.mod.o  Makefile  Module.symvers  symbol[[email protected] module]# 

        注意看hello.ko就出來了。

第二種錯誤：模組程式碼有異常

[[email protected] hello]# makemake -C /opt/kangear/kernel/linux-2.6.32.2 M=/opt/kangear/hello  modulesmake[1]: Entering directory `/opt/kangear/kernel/linux-2.6.32.2'  WARNING: Symbol version dump /opt/kangear/kernel/linux-2.6.32.2/Module.symvers           is missing; modules will have no dependencies and modversions.  CC [M]  /opt/kangear/hello/hello.o/opt/kangear/hello/hello.c:3: error: expected declaration specifiers or '...' before string constant/opt/kangear/hello/hello.c:3: warning: data definition has no type or storage class/opt/kangear/hello/hello.c:3: warning: type defaults to 'int' in declaration of 'MODULE_LECENSE'/opt/kangear/hello/hello.c:3: warning: function declaration isn't a prototype/opt/kangear/hello/hello.c:17: error: redefinition of '__inittest'/opt/kangear/hello/hello.c:16: note: previous definition of '__inittest' was here/opt/kangear/hello/hello.c: In function '__inittest':/opt/kangear/hello/hello.c:17: warning: return from incompatible pointer type/opt/kangear/hello/hello.c: At top level:/opt/kangear/hello/hello.c:17: error: redefinition of 'init_module'/opt/kangear/hello/hello.c:16: note: previous definition of 'init_module' was heremake[2]: *** [/opt/kangear/hello/hello.o] 錯誤 1make[1]: *** [_module_/opt/kangear/hello] 錯誤 2make[1]: Leaving directory `/opt/kangear/kernel/linux-2.6.32.2'make: *** [default] 錯誤 2[[email protected] hello]# make

        這大多是模組程式碼的錯誤，裡邊有中文相關的一些東西了，一些符號。程式碼是在部落格上拷貝的或者是在win下用ue編輯的，直接拷貝到Linux中就會有這種問題。唯一的辦法就是重新打一編程式碼了。目前還沒有找到合適的方法。（語法問題就不提了）

第三種：模組Makefile語法錯誤

[[email protected] hello]# makemake: Nothing to be done for `default'.[[email protected] hello]# 

default:make -C $(KERNELDIR) M=$(PWD)  modules
