一、参考文章：
1. 有谁编译过canutils-4.0.6的吗？
http://bbs.csdn.net/topics/390465516
2. AM335X DCAN Driver Guide
http://processors.wiki.ti.com/index.php/AM335X_DCAN_Driver_Guide#CAN_Utilities
3. AM335x DCAN driver compile issues

二、最后编译出来简略的3层文件结构（tree -L 3):

三、libsocketcan make install 问题：
1. 出错现象：
Qt@zengjf:~/practice/c/canTest/libsocketcan-0.0.8$ make install
Making install in include
make[1]: Entering directory `/home/Qt/practice/c/canTest/libsocketcan-0.0.8/include'
make[2]: Entering directory `/home/Qt/practice/c/canTest/libsocketcan-0.0.8/include'
make[2]: Nothing to be done for `install-exec-am'.
test -z "/home/Qt/practice/c/canTest/libsocketcan-0.0.8/include" || /bin/mkdir -p
"/home/Qt/practice/c/canTest/libsocketcan-0.0.8/include"
/usr/bin/install -c -m 644 libsocketcan.h can_netlink.h
'/home/Qt/practice/c/canTest/libsocketcan-0.0.8/include/.'
/usr/bin/install: `libsocketcan.h' and
`/home/Qt/practice/c/canTest/libsocketcan-0.0.8/include/./libsocketcan.h' are the same file
/usr/bin/install: `can_netlink.h' and
`/home/Qt/practice/c/canTest/libsocketcan-0.0.8/include/./can_netlink.h' are the same file
make[2]: *** [install-nobase_includeHEADERS] Error 1
make[2]: Leaving directory `/home/Qt/practice/c/canTest/libsocketcan-0.0.8/include'
make[1]: *** [install-am] Error 2
make[1]: Leaving directory `/home/Qt/practice/c/canTest/libsocketcan-0.0.8/include'
make: *** [install-recursive] Error 1
2. 解决方法：
export GNUEABI=arm-linux-gnueabihf
export CC=$GNUEABI-gcc
export LD=$GNUEABI-ld
export NM=$GNUEABI-nm
export AR=$GNUEABI-ar
export RANLIB=$GNUEABI-ranlib
export CXX=$GNUEABI-c++filt
export INSTALL_PATH=$PWD
export PREFIX=$INSTALL_PATH/
export CROSS_COMPILE_PREFIX=$PREFIX
export PATH=$TOOL_CHAIN_PATH/bin:$PATH
#./configure --host=arm-linux --prefix=$PREFIX --enable-debug
# 官网给出的安装目录出错导致的，给出合适的安装路径
./configure --host=arm-arago-linux --prefix=$PREFIX/install --enable-debug
四、canutils 找不到 libsocketcan 问题：
1. 错误现象：
checking for pkg-config... /home/Qt/ti-processor-sdk-linux-am335x-evm-01.00.00.00/linux-devkit/sysroots/i686-arago-linux/usr/bin/pkg-config
checking pkg-config is at least version 0.9.0... yes
checking for libsocketcan... no
configure: error: *** libsocketcan version above 0.0.8 not found on your system
2. 解决方法：
export GNUEABI=arm-linux-gnueabihf
export CC=$GNUEABI-gcc
export LD=$GNUEABI-ld
export NM=$GNUEABI-nm

export INCLUDES="-I$LIBSOCKETCAN_INSTALL_DIR/include"
#./configure --host=arm-arago-linux --prefix=$PREFIX --enable-debug
# 加上libsocketcan库的位置
./configure --host=arm-linux --prefix=$PREFIX/install --enable-debug libsocketcan_LIBS=-lsocketcan LDFLAGS="-L$PWD/../libsocketcan-0.0.8/install/lib" libsocketcan_CFLAGS=-I$PWD/../libsocketcan-0.0.8/install/include
五、canutils 安装权限不足：
1. 错误现象：
Qt@zengjf:~/practice/c/canTest/canutils-4.0.6$ make install

2. 解决方法：
export GNUEABI=arm-linux-gnueabihf

export NM=$GNUEABI-nm
export AR=$GNUEABI-ar
export RANLIB=$GNUEABI-ranlib
