Error: collect2.exe: error: ld returned 1 exit status, how to fix?

Question

C++ / C#

I wrote in dev c++, the most common compiler, TDM GCC, wrote the code (first the necessary code, then just "Hello" to check). And every time this was output - c:\program files (x86)\dev-cpp\mingw64\x86_64-w64-mingw32\bin\ld.exe cannot open output file C:\Nurzhan\Programming\с++\main.exe : Permission denied
and this is C:\Nurzhan\Programming\c++\collect2.exe [Error] ld returned 1 exit status
Compiled via cmd too, but no result
How to fix this?
I'm a student!

Answer 1

ld.exe cannot open output file C:\Nurzhan\Programming\c++\main.exe: Permission denied
How do I fix this?

It looks like the executable file is running, so Windows does not allow it to be overwritten.
Kill the process started from main.exe, then compile.
