I've tried to start building my project with xfbuild today (running
everything through DMD was finally starting to get slow), and every so
often, Optlink dies with something like this:

To me, this looks like I'm somehow missing template implementations. When I
delete all the object files and build again, everything generally works. Is
there any reason this happens and/or a way to fix it?

 To me, this looks like I'm somehow missing template implementations.
 When I delete all the object files and build again, everything generally
 works. Is there any reason this happens and/or a way to fix it?

I think this is because DMD only output templates to one object file instead of to all object files. In addition to that there's now way to tell DMD or know in which object file it will output the templates. I think Walter has said that DMD will output templates to all object files if you compile with the -lib switch. You can try and see if you can modify xfbuild to use the -lib switch. -- /Jacob Carlborg

What was Walter's reasoning for this? Would he be willing to accept a pull request for a command line switch to output templates to all object files for situations like these? -- Robert http://octarineparrot.com/

I have no idea if he will accept a pull request for this. I think it would be great if DMD had a switch like that. This would make it easier to build an incremental build tool. Also pull request 11 would help a lot: https://github.com/D-Programming-Language/dmd/pull/11 -- /Jacob Carlborg
