Hello Jakob, Many thanks. I haven't yet read the workflow you referenced. I will though.
Regarding the quick try of adding `v8_optimized_debug = false` to my gn gen line - that did not help. ie.: `gn -v gen out/arm64.debug --args='is_debug=true target_cpu="arm64" v8_target_cpu="arm64" is_component_build=true v8_optimized_debug=false'` On Wednesday, July 10, 2024 at 5:22:53 AM UTC-4 Jakob Kummerow wrote: > You may be missing the v8_optimized_debug = false build flag. > Debug symbols are controlled by the symbol_level flag, which should > default to 2 in debug builds, but it might help to manually set that.
