I am not trying to install anything. But the error message

gcc: error: unrecognized command line option ‘--showme:link’

pops up as the first line in my terminal whenever I launch it.

The problem existed in 14.04 and still exists after upgrading to 16.04.

Any idea why this happens and possible solutions?

    Does commenting out source /opt/openfoam30/etc/bashrc solve it?

Your ~/.bashrc has the following line at the end:

source /opt/openfoam30/etc/bashrc

i.e. bash will source /opt/openfoam30/etc/bashrc while starting an interactive session.

And in that file you have the potential problem as other portions seem fairly normal. But the interesting thing is that file does not directly call gcc but it sources so many other files, it really hard to get to the specific file/line that is causing this issue.

Instead, as an trial and error method (and also being confident that this should be the problematic one), you can comment out the line from ~/.bashrc:

# source /opt/openfoam30/etc/bashrc

And as per your comment, it worked !! The error message is gone.


For future, the first step to debug these sort of bash session starting related issue, check if the relevant files have anything:

For Login Interactive session of bash:

grep -Hn 'gcc' ~/.bashrc /etc/bash.bashrc ~/.profile /etc/profile

For Non-login Interactive session of bash:

grep -Hn 'gcc' ~/.bashrc /etc/bash.bashrc

If not, read the relevant files, you should get a hint to debug further.
