#18553) This PR disables passing `-dead_strip` to the native linker in case of NativeAOT runtime to prevent build failures. Additionally, this change affects the size of the application in the following way - measured with `dotnet new maui` app version `8.0.0-preview.7.23359.1`: | MAUI iOS | -dead_strip | no -dead_strip | diff (b) | diff (Kb) | diff (%) | |----------|--------------|----------|----------|-----------|----------| | .ipa (b) | 13377583 | 13435276 | 57693 | 57,693 | 0,43% | | Size on disk (b) | 41883897 | 42038873 | 154976 | 154,976 | 0,37% | | binary (b) | 39614336 | 39769312 | 154976 | 154,976 | 0,39% | Even though the size of the application regresses, with this change we have a more stable product. Finally, once this PR gets merged we can open a tracking issue to solve the size regression either by fixing: - dotnet/runtime#88032 or - by manually removing the dead code as proposed by @filipnavara here: dotnet/runtime#88032 (comment) --- Fixes: #18552

Description
As reported in: dotnet/runtime#88032 NativeAOT can produce object files which cause the native linker to seg fault during linking when
-dead_stripis enabled.This issue is reproducible with
.NET8 preview 6release: https://github.com/xamarin/xamarin-macios/tree/release/8.0.1xx-preview6 when buildingMAUI Podcast appwith NativeAOT, resulting with build failures.Proposal
As a workaround, do not include
-dead_stripas an optimisation switch to the native linker in case of NativeAOT runtime, so we ship a more stable product in.NET8 preview 7releaseThe text was updated successfully, but these errors were encountered:
