gcc is not using /tmp for temporary files

Question

I am using Ubuntu Linux.

gcc is not using /tmp for temporary files (.i, .o, .s).

I exported environment variable TMPDIR like this:

export TMPDIR=/tmp

however gcc still tries to create tmp files in ./ so, if there is no W permission, gcc fails.

So I want to fix the gcc temporary file path to /tmp/ however, gcc is ignoring the TMPDIR .

What would be the problem here?

Answer 1

Adding the:

export TMPDIR=$HOME/temp;

line to ~/.profile file and then running:

. ~/.profile

command followed by a system restart did the trick for me in case anyone comes across this.
