Migration to .net 6 Unable to load ICU library

Question

I am getting this error

Exception message: Unable to load ICU library.;
Inner exception: ;
StackTrace: at DevExpress.Text.Interop.ICUInterop.LoadSharedLibrary(NativeLibraryLoader libraryLoader)
at DevExpress.Text.Interop.ICUInterop.<>c.<.cctor>b__9_0() 

during converting html to pdf in my app after migration to.Net 6

I am running .NET 6.0.7 in docker container alpine.3.16-x64

FROM mcr.microsoft.com/dotnet/aspnet:6.0.7-alpine3.16

ARG APP_DIRECTORY

WORKDIR /app

RUN apk add --no-cache harfbuzz-icu ttf-opensans && \
    apk add --no-cache --repository http://dl-cdn.alpinelinux.org/alpine/v3.8/main libcrypto1.0 libssl1.0 && \

ENV DOTNET_SYSTEM_GLOBALIZATION_INVARIANT=true

My runtimeconfig.json

{
  "configProperties": {
    "System.Drawing.EnableUnixSupport": true,
    "System.Globalization.Invariant": true
  }
} 

Does anybody faced the same problem during upgrading from 5.0 to 6.0?

Answer 1

The problem is in ICU library. Alpine3.16 has icu version 71

https://github.com/unicode-org/icu/releases/tag/release-71-1

So we downgraded to alpine3.15 which has icu version 69 and everything works.
