digitalmars.D.bugs - [Issue 19291] New: undefined reference linker error with separate


          Issue ID: 19291
           Summary: undefined reference linker error with separate
           Product: D
           Version: D2
          Hardware: x86_64
                OS: Linux
            Status: NEW
          Severity: normal
          Priority: P1
         Component: dmd
          Assignee: nobody puremagic.com
          Reporter: zorael gmail.com

Manjaro/Arch x86_64, dmd v2.082.0, dub v1.11.0.

The code in the linkererror branch at
https://github.com/zorael/kameloso/tree/linkererror compiles in normal mode but
gives an undefined reference error when building with dub

The error disappears and compilation succeeds if a local import inside a
function (main) is moved up to module-level.

 $ git clone https://github.com/zorael/kameloso -b linkererror
 $ cd kameloso
 $ dub build --build-mode=singleFile
 /usr/bin/ld: .dub/build/application-debug-linux.posix-x86_64-dmd_2082-6DCE8163999240FCF02537A83F2B5
