I have two project I want to compile and both times get this error:

Undefined symbols for architecture x86_64:
 "_dyld_enumerate_tlv_storage", referenced from:
     __d_dyld_getTLSRange in libphobos2.a(osx_tls.o)

I'm wondering where this comes from as I didn't see it in the past. Any idea?

I had the same missing symbol at runtime, when trying to run an already compiled binary (LDC 1.16 I think) after a Catalina update. In that case, recompiling (LDC 1.17 or DMD 2.088.0) was apparently enough to mitigate the issue.

Ah, I should have read this before replying; that's precisely the issue I had.

Any D application needs to be compiled with DMD 2.087.1 or later or the corresponding version of LDC to be able to run on macOS Catalina. That includes DMD itself. The oldest version of DMD that runs on Catalina is 2.088.0, since any given version of DMD is compiled with the previous version.

That means that all D applications out there for macOS needs to be recompiled.

I think I had an older one like 2.085 or so. I updated to 2.088 and it now seems to work.

I'm on OSX 10.14.6, so this might not be directly related to Catalina but maybe more to the XCode Version installed:

| => xcrun --show-sdk-version
10.15

So, it's possible to run 10.14 with SDK version 10.15 which seems to trigger the problem.

Thanks for the hints.

No, I don't think that's the problem. I have the same setup and I don't have this problem.

What result do you get if you run the following command:

nm /usr/lib/system/libdyld.dylib | grep _dyld_enumerate_tlv_storage

I get this since Catalina:

Joel-Computer:VacSpace joelchristensen$ dub
Failed to invoke the compiler dmd to determine the build platform: dyld: lazy symbol binding failed: Symbol not found: _dyld_enumerate_tlv_storage
  Referenced from: /usr/local/bin/dmd
  Expected in: /usr/lib/libSystem.B.dylib

dyld: Symbol not found: _dyld_enumerate_tlv_storage
  Referenced from: /usr/local/bin/dmd
  Expected in: /usr/lib/libSystem.B.dylib


Joel-Computer:VacSpace joelchristensen$

I use Home Brew (brew upgrade dmd, and brew upgrade dub)
Brew is only up to 2.087.1 at the moment - John Colvin seems to be the man that mantains dmd with brew.

Interesting... but the update seems to have solved the problem. Maybe some old DMD compiler stuff lying around got in the way.

=> nm /usr/lib/system/libdyld.dylib | grep _dyld_enumerate_tlv_storage
0000000000017eca T _dyld_enumerate_tlv_storage

I confirm that DMD downloaded from the official script works like charms on Catilina. You can rely on that right now ...
