http://d.puremagic.com/issues/show_bug.cgi?id=935 Summary: Extern Global C Variables Product: D Version: 1.00 Platform: PC URL: http://www.digitalmars.com/d/htomodule.html OS/Version: Windows Status: NEW Severity: normal Priority: P3 Component: www.digitalmars.com AssignedTo: bugzilla@digitalmars.com ReportedBy: torhu@yahoo.com Under the heading 'Extern Global C Variables', it's explained that you need to create an extra module that is not linked with, in order to avoid a multiple definition error. But given a C header file: struct Foo { }; struct Foo bar; It's enought just to have a single module, like this: struct Foo { } extern extern (C) Foo bar; The first 'extern' makes bar a pure declaration, and the definition in the C library will be used. Tested with dmd 1.0 and 1.004. -- |
