Declaration of 'varaible 1' hides global variable (warning) Please help, cannot find the solution sine hours!

New comment
 
Hy guys, please help me the following issue. I researched for many hours already and cannot fix this issue.

mq4 file:


#include <TEST.mqh>

// Input parameters
input int variable1  = 10;

input double variable2 = 20;

No warning when I only compile the mq4 file(where I also use these variables) but when I include the TEST.mqh i get this Declaration of 'varaible 1' "variable2" hides global variable warning. 

TEST.mqh  code example

// -- Trade Logic -- 

ENUM_ORDER_TYPE GetTrade(int variable1, double variable2) 


I triple checked, there is no other declaration for these variables in another section of the code. 


Thank you very much for your support!

  1. In your function, you have a local variable (first parameter) and a globally declared variable with the same name.
  2. If you intend to only use the global ones, remove the parameters from your function definition.

In this case, TEST.mqh compilation errors will occur (when compiled separately from the mq4 file). I think it's better to just make the identifiers different

MQH indicates an include (header) file. You do not compile them, you include them.

I always compile mqh files so that the compiler can check them. I believe that every header file should compile without errors and warnings regardless of the mq4/5 file.

That is, when I write another mqh file, I compile this mqh file to immediately check the just written code for errors without having to return to the mq4 file, which often I don’t even have open.

This is what the mq4 file of the expert I'm working on at the moment looks like:

I don't need this file 99.9% of development time (thanks to the fact that I compile mqh files for the compiler to check for errors😄)
