When compiling an mq4 file to ex4 file, how does it affect the extension file. Or better still how can the extension file be compiled to become ex4 file too? I will appreciate an idea for a solution

I just want to know. I have been trying to use the metaeditor compiler or by pressing f5 to conver mq4 to ex4 file but it says "compiling .....My EAs name" and it is as if it will continue forever. How do I know when it has finish compiling the file and where can I locate it? Please, if anyone has the idea, he or she should tell me
