Using 2.096.0, I'm getting a number of "undefined reference"
linker errors that I haven't been able to figure out how to
resolve.
The first linker error is undefined reference to
std.typecons.Typedef:
```
src/phobos/std/typecons.d:7569: error: undefined reference to
'_D3std8typecons__T7TypedefTmVmN1VAyaa20_466c617441646472657373436f6d706f6e656e74ZQCl6__initZ'
```
The module that I am compiling/linking imports std.typecons :
Typedef at the top of the file. I have compiled the file, run
`strings` on the output file, and grep'd the output for the
missing symbol reported by the linker and it is in the list of
symbols.
The second linker error is undefined reference to
core.internal.SwitchError:
```
src/phobos/std/range/package.d:9752: error: undefined reference
to '_D4core8internal7switch___T14__switch_errorZQrFNaNbNiNfAyamZv'
```
This shows up anywhere I have a `final switch` in the code. Like
the Typedef error, this symbol also shows up in the list of
symbols.
The third linker error I'm getting is undefined reference to a
function that is defined in the module and then referenced later
inside a class that is also defined in that module after the
function. Again, I'm not sure why the linker would think it is
undefined since it is defined in the same module. I did try
moving the function definition inside the class and the linker
errors associated with that function go away.
The code compiles and links with 2.091.1 but I'm not sure what
has changed since then that might cause this problem. I am
working on creating a reduced test case using Dustmite but
haven't been successful yet as it keeps reducing to an empty set.
Any tips on what to do/check?
Thanks!
