What is the correct file structure?

[eabase]

I'm trying to run the Example "HelloWorld" code, but I keep getting errors about the correct path.

can't open "C:\Users\user\AppData\Roaming\MetaQuotes\Terminal\hash\MQL4\Include\Zmq\Zmq.mqh" include file HelloWorldClient.mq4

Currently it looks like this:

C:/Users/<user>/AppData/Roaming/MetaQuotes/Terminal/<hash>/MQL4/Include/Zmq (master)
$ tree -L 4 ./

Is this not correct?

No, you need to follow the instructions of the installation guide, coping the files from this repo to the respective folder of your MT source. https://github.com/dingmaotu/mql-zmq#files-and-installation

You need to copy the files and replace than respectively to the structure of your folder C:/Users/<user>/AppData/Roaming/MetaQuotes/Terminal/<hash>/MQL4/

@raulvictorrosa It would have been much easier to understand if you just posted the output of your structure with the tree command. Because to the looks of it, my shown above, is the same as yours. (I.e. What is wrong with my path?)

@eabase you should copy DLLs from MT4 OR MT5 and put them directly under your Library folder.
