Metaeditor build does not run in Metatrader

“Doesn't work” is meaningless — just like saying the car doesn't work. Doesn't start, won't go in gear, no electrical, missing the key, flat tires — meaningless.

There is no compiler in the terminal, you are talking non-sense.

@William Roeder #: There is no compiler in the terminal, you are talking non-sense.

I think the user is probably referring to the auto-compilation that the terminal carries out when it starts up and detects source files without the respective executable.
