I have compiled gcc 4.9 in CentOS 6.5 which had gcc 4.4.7 by default. the default gcc is contained is /usr/bin directory. I have compiled a newer version gcc 4.9 in /usr/local/gcc4.9 directory and added this path in .bashrc as folllow export PATH=$PATH:/usr/local/gcc-4.9.1/bin export LD_LIBRARY_PATH=$LD_LIBRARY_PATH:/usr/local/gcc-4.9.1/lib/ But still the Linux find the gcc4.4.7 version and unable to find the newly compiled one.
