When I get a build error there are text files I could potentially upload with my forum post when asking for support, but that option isn’t allowed.
for example when running ./gradlew dist distPlatformLibs and compilation fails for me then ./kotlin-native-1.4.0/libclangext/build/tmp/compileClangextStaticLibraryClangextCpp/output.txt and options.txt might be useful to whoever decides to help me.
