I installed the free version of juliapro-mkl in manjaro. When using julia from the terminal by typing

> julia -O3 test.jl

I got "ERROR: julia: invalid argument to -O (3 test.jl)

when I type

> julia --math-mode=fast test.jl

I got "ERROR: julia: invalid argument to --math-mode (fast tdse.jl)  
when I type

> julia test.jl -O3

I got “ERROR: could not open file /home/cyb/test.jl -O3”
