When I install GCC5.4 followed the dev guide, It seems not succeed.
tar -jxf gcc-arm-none-eabi-5_4-2016q2-20160622-linux.tar.bz2renyusang@ubuntu:~$ exportline=“export PATH=$HOME/gcc-arm-none-eabi-5_4-2016q2/bin:$PATH”
if grep -Fxq “$exportline” ~/.bash_profile; then echo nothing to do ; else echo $exportline >> ~/.profile; fi
grep: /home/renyusang/.bash_profile: No such file or directory
arm-none-eabi-gcc --version
bash: /home/renyusang/gcc-arm-none-eabi-5_4-2016q2/bin/arm-none-eabi-gcc: No such file or directory\
