linux 编译kernel与svn版本冲突解决方法

现象

系统本来可以正常编译linux系统kernel,但在安装svn后,kernel编译出错。

  CHK     include/linux/version.h
  CHK     include/generated/utsrelease.h
make[1]: `include/generated/mach-types.h' is up to date.
  CALL    scripts/checksyscalls.sh
  CHK     include/generated/compile.h

原因分析

定位到 drivers/gpu/mali/ump/Makefile.commondrivers/gpu/mali/mali/Makefile 两个文件中都有关于SVN_REV:=xxxx的语句,正常情况下SVN_REV:=为空,当检查到svn版本后,SVN_REV:=有了值,导致脚本中判断走入错误分支。

解决方法

将两个文件中的SVN_REV值都赋值为空“”即可。

drivers/gpu/mali/ump/Makefile.common:

 16 # Get subversion revision number, fall back to 0000 if no svn info is available
 17 #SVN_REV:=$(shell ((svnversion | grep -qv exported && echo -n 'Revision: ' && svnversion) || git svn info | sed -e 's/$$$$/M/' | grep         '^Revision: ' || echo ${MALI_RELEASE_NAME}) 2>/dev/null | sed -e 's/^Revision: //')
 19 SVN_REV:=""

drivers/gpu/mali/mali/Makefile:

117 #SVN_REV := $(shell (cd $(DRIVER_DIR); (svnversion | grep -qv exported && svnversion) || git svn info | grep '^Revision: '| sed -e 's/        ^Revision: //' ) 2>/dev/null )
119 SVN_REV := ""
