[Gmsh] Gmsh Tutorial 1 fails...?

[Zuheyr Alsalihi]

Dear gmsh Community,

I am using the following executable downloaded today, 24/06/2018:
gmsh-3.0.6-Linux64/bin/gmsh


I copied and pasted the t1.geo from Prof. Geuzaine's gmesh Website which 
is attached.
I seem to do a mistake as I get errors which are saved and attached here 
in error.txt file.

In view of my other problems for which I have been asking your valuable 
help, perhaps
I am doing some fundamental mistakes as I am a beginner but we would 
like to use gmsh at our Institute.

Thank you very for reading.

Kind regards,
Zuheyr
