Some general advice:
1 - use `dub` from LDC's package (this may solve some arm64 vs
x86 issues when on Apple Silicon CPU)
2 - when you use a new or different compiler, you have to
rebuild _all_ packages. So clear your dub cache.
I think point 2 is causing your issues.

Hi again, I hate to repeat myself, but the linker issues on
MacOS keep happening, even after using this in the dub recipe:
```
lflags "-ld_classic"
```
Even though this helps, every now and then I am faced with a
horrible error like this (happened on multiple projects):
```
ld: warning: pointer not aligned at address 0x10017FA3A ('anon'
+ 115 from
../../../.dub/cache/prettyprint/1.0.9/build/library-unittest-zRys5rzGP6krRGvFrhQ1nw/libprettyprint.a(primitives_64_42b.o))
ld: warning: pointer not aligned at address 0x10017FACD ('anon'

../../../.dub/cache/prettyprint/1.0.9/build/library-unittest-zRys5rzGP6krRGvFrhQ1nw/libprettyprint.a(primitives_65_55a.o))
.... hundreds of lines just like this

```
It doesn't matter if I use LDC or DMD. Both cause the same
error.
I've tried cleaning the DUB cache like this:
```
rm -rf ~/.dub/cache
```
But it doesn't help.
It's very frustrating because I'm close to finishing my
project, but this kind of random error really delays me... it
seems that as I keep changing code, the linker eventually
starts working again! I must be hitting some "bad path" in the
compiler.
So, if anyone who understands about linking on MacOS could have
a look, here's a commit on the project I'm currently working on
which shows this problem:
https://github.com/renatoathaydes/dzipper/commit/54d1f90f18a17d87d71195df68d02089ca4cf27c
If you checkout this commit, just run `dub test` and you should
see the problem on MacOS Sonoma.
Notice that the current state of my code is "in progress" so
some stuff may not even be working properly yet, the tests may
not even be passing, that's fine (if I only I could run the
tests)... but as the error is on the linker, I believe it's
compiling properly and there should never be any linker errors
like this.
dub might not be passing this flag down to dependencies..
Try this env variable:
``LDFLAGS="$LDFLAGS -Wl,-ld_classic" dub build``
If that doesn't work, try this one:
``MACOSX_DEPLOYMENT_TARGET=11 dub build``
