I have downloaded the toolchain from following link
https://launchpad.net/gcc-arm-embedded/5.0/5-2016-q1-update/+download/gcc-arm-none-eabi-5_3-2016q1-20160330-linux.tar.bz2
在ng-grid中显示数据我制作了一个脚本，将其添加到环境路径
export INSTALL_ROOT=`pwd`
TOOLS_PATH=$INSTALL_ROOT/
CROSS_PATH=$TOOLS_PATH/arm-none-eabi/bin
export PATH=$TOOLS_PATH/bin:$CROSS_PATH:$PATH
# Path to cross-tools
export CROSS_COMPILE=arm-none-eabi-
export CROSS_COMPILE_APPS=arm-none-eabi-
但如果我在交叉编译中使用它，即使用./configure --error来
./configure --host=arm-none-eabi
checking build system type... i686-pc-linux-gnu
checking host system type... arm-none-eabi
checking target system type... arm-none-eabi
checking for arm-none-eabi-gcc... arm-none-eabi-gcc
checking whether the C compiler works... no
aconfigure: error: in `/home/sameer/Downloads/pjsip_experiment/0706/pjproject-2.4.5':
aconfigure: error: C compiler cannot create executables
See `config.log' for more details
如果我只是编译一个helloworld程序，那么也会出现错误
arm-none-eabi-gcc hello.c -o out
