Hi, While attempting to build "secret-project" I encountered this [ 7 of 10] Compiling Installer.UI ( Installer/UI.hs, .stack-work/dist/x86_64-linux-nopie/Cabal-1.24.2.0/build/propellor-config/propellor-config-tmp/Installer/UI.o ) /home/stappers/src/secret-project/Installer/UI.hs:228:14: error: Not in scope: ‘UI.loadFile’ Module ‘Graphics.UI.Threepenny’ does not export ‘loadFile’. -- While building custom Setup.hs for package secret-project-0.0 using: /root/.stack/setup-exe-cache/x86_64-linux-nopie/Cabal-simple_mPHDZzAJ_1.24.2.0_ghc-8.0.2 --builddir=.stack-work/dist/x86_64-linux-nopie/Cabal-1.24.2.0 build exe:propellor-config --ghc-options " -ddump-hi -ddump-to-file" Process exited with code: ExitFailure 1 From I understand that a UI patch to threepenny-gui is needed. But I don't understand that request. How to patch the threepenny-gui?? Cheers Geert Stappers
