Dear all
I want to use gretl library functions in mql4 programming mql4 can import .mqh or .dll file using following codes.I don't have much knowledge to convert the files, and decided to ask here to send me gretl dll library files.


Hi Yashar, I don't know what mql4 is, but when you talk about dll files I'm assuming you're on Windows.
So AFAICS the easiest way to get the gretl dll files is to install gretl on your machine with the standard installer from the sourceforge download page. Then in your install location you will have for example the file libgretl-1.0-1.dll, which is around 4MB here on my system.

Perhaps the following page could also be useful:
