现象

从 svn 仓库check out 一份内核， 然后make (该配置内置了initramfs 文件系统)，第一次make 成功， 但是此后再也不行了！make , make clean 等后都会出错。给开发带来极大麻烦。   出错信息如下： 20081007_kernel>make   CHK     include/linux/version.h make[1]:`include/asm-arm/mach-types.h' is up to date.   CHK     include/linux/utsrelease.h   CHK     include/linux/compile.h /home/zjujoe/svn/mhlv_2.6/working/songlixin/20081007_kernel/usr/Makefile:41:*** multiple target patterns.  Stop. make: *** [usr] Error2   20081007_kernel>make clean   CLEAN   arch/arm/boot/compressed   CLEAN   arch/arm/boot   CLEAN   /home/zjujoe/svn/mhlv_2.6/working/songlixin/20081007_kernel   CLEAN   arch/arm/kernel   CLEAN   drivers/char   CLEAN   init   CLEAN   lib /home/zjujoe/svn/mhlv_2.6/working/songlixin/20081007_kernel/usr/Makefile:41:*** multiple target patterns.  Stop. make: *** [_clean_usr] Error2   20081007_kernel>makedistclean /home/zjujoe/svn/mhlv_2.6/working/songlixin/20081007_kernel/usr/Makefile:41:*** multiple target patterns.  Stop. make: *** [_clean_usr] Error2    

问题解决

(同时打算再仔细研究一下 Makefile 语法:P) google 了一下， 查到文档: http://www.ibm.com/developerworks/cn/linux/l-debugmake.html   该文档说make 时使用  -d 参数可以看到大量信息， 试着用 make–d, 最后几行： This program built fori486-pc-linux-gnu Reading makefiles... Reading makefile`scripts/Makefile.build'... Reading makefile`include/config/auto.conf' (search path) (don't care) (no ~expansion)... Reading makefile`scripts/Kbuild.include' (search path) (no ~expansion)... Reading makefile`/home/zjujoe/svn/mhlv_2.6/working/songlixin/20081007_kernel/usr/Makefile'(search path) (no ~ expansion)... Reading makefile`usr/.initramfs_data.cpio.gz.d' (search path) (no ~expansion)... /home/zjujoe/svn/mhlv_2.6/working/songlixin/20081007_kernel/usr/Makefile:41:*** multiple target patterns.  Stop. Reaping losing child 0x080af520PID 6349 make: *** [usr] Error2 Removing child 0x080af520 PID6349 from chain.   看一下，usr/.initramfs_data.cpio.gz.d 为initramfs 的目录列表， 试着删除文件 usr/.initramfs_data.cpio.gz.d 再 Make, 居然不出错了！！！   20081007_kernel>rm -fusr/.initramfs_data.cpio.gz.d 20081007_kernel>make   CHK     include/linux/version.h make[1]:`include/asm-arm/mach-types.h' is up to date.   CHK     include/linux/utsrelease.h   CHK     include/linux/compile.h   MODPOSTvmlinux   Kernel:arch/arm/boot/Image is ready   Kernel:arch/arm/boot/zImage is ready   Building modules, stage2.   MODPOST 33modules
