---|---|---|---|---|
| ||||
Glad to announce the first beta for an exciting LDC 1.21 release: * Based on D 2.091.0; LLVM upgraded to v10.0.0-rc4. * Experimental iOS/arm64 support. * Initial support for GCC/GDC-style inline assembly syntax, primarily for portability across GDC and LDC (and GCC-style C). * Android improvements, incl. an important fix for x86 architectures, usability of the ld.gold linker and no more D `main()` requirement. * Important AArch64 bugfix, especially for unoptimized code. Full release log and downloads: https://github.com/ldc-developers/ldc/releases/tag/v1.21.0-beta1 Please help test, and thanks to all contributors! |

Are you sure you are linking with that `kdtree` module?
Upgrading the compiler often uncovers latent linking dependency bugs (possibly 1.20 optimizes / codegens things slightly different).

Well, thx for giving it a try, but that's hardly useful (just looks like a `kdtree` module not being compiled) - firstly, try to check whether that's LDC-specific (i.e., doesn't happen with the corresponding DMD version 2.091.0), and if so, please file a GitHub issue with reproduction steps.

It was a dependency bug in my build process uncovered by the new LDC, as Johan suggested. In my superficial scan of the source code, I did not find any kdtree module and so was thinking (incorrectly) that it might be a compiler-supplied module. Turns out that it was a module recently added by a colleague. LDC 1.21.0-beta1 was correct to identify it as missing from the build. Interestingly, DMD 2.091.0 built the code without complaint.
Apologies for the bother but thank you for all of the work on LDC (and for the gentle replies to my report).
