[QE-users] issue installing qe-6.4.1 in Mac OS, "/lib/cpp fails sanity check"

[Seyed Mohammad Farzaneh]

Greetings,

I had the same problem with the configure. I was able to resolve the issue
by changing the PATH variable.
I guess, there are two paths for gcc and cpp on your mac machine:
usr/local/bin/ and usr/bin/
If you put the usr/bin/ upfront in the PATH variable the error will
hopefully go away.
You can do this by adding the following at the end of your .bash_profile:
export PATH=/usr/bin:$PATH

Best,
SMF
