cdrtools-3.02 arm7 交叉编译通过

1) uname -a  查看 armv7l 内核2.6
Linux dvr 2.6.37 #57 Fri Aug 14 10:35:26 CST 2015 armv7l unknown
设置编译环境：

export PATH=/home/yod/workbench/github/out_project/2016-01-25/toolchain/bin/:$PATH
export CONFIG_RMTDEBUG=true
export CONFIG_RMTCALL=:
export CC=/home/yod/workbench/github/out_project/2016-01-25/toolchain/bin/arm-linux-gcc
export CONFIG_RMTHOST=NONE
export SYSROOT=/home/yod/workbench/github/out_project/2016-01-25/toolchain/arm-none-linux-gnueabi/libc

编译：
make ARCH=armv7l OSNAME=linux CCOM=gcc "CC_COM=$CC"
会报错，
然后开始查找错误：
主要是以下为空或者不存在，
incs/armv7l-linux-gcc/align.h
incs/armv7l-linux-gcc/avoffset.h

修改步骤：
a)
diff --git a/RULES/rules.inc b/RULES/rules.inc
 15 index e0c3ea8..fe790c4 100755
 16 --- a/RULES/rules.inc
 17 +++ b/RULES/rules.inc

b)拷贝如下到板子上，
./inc/OBJ/armv7l-linux-gcc/align_test > align.h        
./inc/OBJ/armv7l-linux-gcc/avoffset  > avoffset.h
分别运行 生成对应头文件，然后copy回来，放到 incs/armv7l-linux-gcc/

c) cdrtools-3.02 源码，重新从解压处获取一份。然后make，直接在linux下编译，应该是直接编译过去的。然后对比xconfig.h 文件；
/home/yod/workbench/github/out_project/arm/new_0127/cdrtools-3.02/incs/armv7l-linux-gcc/xconfig.h
/home/yod/workbench/github/out_project/cdrtools-3.02_linux/cdrtools-3.02/incs/x86_64-linux-cc/xconfig.h
主要修改
#define SIZEOF_CHAR  1
#define SIZEOF_SHORT_INT 2
#define SIZEOF_INT 4
#define SIZEOF_LONG_INT 4
#define SIZEOF_LONG_LONG 8
#define SIZEOF___INT64 0
#define SIZEOF_CHAR_P 4

#define SIZEOF_DOUBLE 8
#define SIZEOF_LONG_DOUBLE 8

#define SIZEOF_SIZE_T 4

#define SIZEOF_MODE_T  4
#define SIZEOF_UID_T 4
#define SIZEOF_GID_T 4
#define SIZEOF_PID_T 4
请参考align.h  里面的sizeofint等，


然后再
make ARCH=armv7l OSNAME=linux CCOM=gcc "CC_COM=$CC"
这次应该成功了。







sudo make install  ARCH=armv7l OSNAME=linux CCOM=gcc "CC_COM=$CC"
