Sorry, typo. Semicolon is included in the file. DMD 2.060.

You druntime installation is bad due to some cruft left from a previous install (the installer obviously needs some work). If you used an installer, then uninstall dmd, make sure that it's completely removed, and then reinstall it. If you installed it manually, then make sure that you blow away druntime's import directory and then restore it with the current version of those files. - Jonathan M Davis

Thanks. Had not tried that and it sounds as a probable reason.

Reinstallation solved the case. Thanks for your prompt reply.

I am having this issue now. What else would I need to do other than uninstall and reinstall D on Windows to get it working? I tried that and it's not fixed it. Importing std.random in my own module which is in the project directory fails to find the symbol while importing std.algorithm works fine. Importing std.random in main.d works fine as well. Error 1 Error 42: Symbol Undefined _D7objects12__ModuleInfoZ

How do you build your program? Dmd, rdmd, Dub, etc.?

Dmd latest non-beta, with the latest VisualD. Debug build. Debug build and no additional or non default settings.

Hmm.. Did you verify that the D installation directory was completely empty after uninstalling? Does VisualD have some kind of verbose mode to show the exact command used to invoke DMD? What happens if you run rdmd on your main file?

It seems to work fine with RDMD. I don't know if VisualD has a verbose mode. Would this suggest the issue is with VisualD or with DMD settings in some way?
