Not able to point GCC specific version

Question

I followed these steps for installing a gcc 8.4 version on a custom folder (--prefix = /FOLDER/)

https://www.hongliangjie.com/2012/07/20/how-to-install-gcc-higher-version-in-alternative-directory/

But I'm not able to use the new gcc 8.4. Everywhere I do 'gcc -v' I get gcc version 4.8. I've tried also in /FOLDER/, /FOLDER/bin but no way. Neither 'gcc-8'

I'm working on my pivate space on a cluter via 'ssh', so no root permission.

I saw previous question but using

export LD_LIBRARY_PATH=$LD_LIBRARY_PATH:/FOLDER/libexec/gcc/powerpc64le-unknown-linux-gnu/8.4.0

not working.

Any help?

Either you call this gcc with an absolute path,

/FOLDER/bin/gcc --version

or you add its location to your PATH:

export PATH=/FOLDER/bin:$PATH
gcc --version

Unix does not add the current directory to PATH as Windows does, so to run the new gcc from /FOLDER/bin you'd have to specify to search from the current location:

cd /FOLDER/bin
./gcc --version
