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_UNSIGNED_CHAR 1

#define SIZEOF_UNSIGNED_SHORT_INT 2

#define SIZEOF_UNSIGNED_INT 4

#define SIZEOF_UNSIGNED_LONG_INT 4

#define SIZEOF_UNSIGNED_LONG_LONG 8

#define SIZEOF_UNSIGNED___INT64 0

#define SIZEOF_UNSIGNED_CHAR_P 4

#define SIZEOF_FLOAT 4

#define SIZEOF_DOUBLE 8

#define SIZEOF_LONG_DOUBLE 8

#define SIZEOF_SIZE_T 4

#define SIZEOF_SSIZE_T 4

#define SIZEOF_PTRDIFF_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"
