secret-project and Module ‘Graphics.UI.Threepenny’ does not export ‘loadFile’.

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 )

From http://propellor.branchable.com/forum/secret-project_and_type_constructor_or_class___8216__PartSpec__8217__/#comment-179662ace1bc9a24782d60e73f2a5a4e 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

There was another error before the error reported above. It was

Error: While constructing the build plan, the following exceptions were encountered:

needed since secret-project is a build target.

My workaround was

That because stack.yaml has a package line

where I think/assume the 0.7.0.1 comes from.

The zip file pointed to by the stack.yaml file contains a patched version of threepenny-gui 0.8.0.0, the same as the cabal file requires.

Downgrading the dependency won't work, thus your build problems. All I can tell you is it's built successfully with stack every time I've tried to build it, and stack pins all package versions to ensure a reproducible build.

It may be that you're using too old a version of stack or something like that; I've used stack 1.1.2.

threepenny-ui in cabal

Without a version for threepenny-ui in secret-project.cabal gets 0.7.0.1 installed by stack build.

Where 0.7.0.1 comes from is unclear to me. Downloading and unzipping https://github.com/joeyh/threepenny-gui/archive/59242cf93bdb8eaa805f5c2b0241e9a1cba9a70f.zip didn't reveal any 0.7.0.1.

Having threepenny-gui (>= 0.8.0.0) in secret-project.cabal gives this compile error:

Error: While constructing the build plan, the following exceptions were encountered:

In the dependencies for secret-project-0.0:
    threepenny-gui-0.7.0.1 from stack configuration does not match (>=0.8.0.0) (latest matching version
                           is 0.8.2.0)
needed since secret-project is a build target.

Some potential ways to resolve this:

  * Recommended action: try adding the following to your extra-deps
    in /home/stappers/src/secret-project/stack.yaml:

- threepenny-gui-0.8.2.0

  * Set 'allow-newer: true' to ignore all version constraints and build anyway.

  * You may also want to try using the 'stack solver' command.

Plan construction failed.

I hope it is reproduceable and that it can be fixed.

You need this for it to build with the newer stack:

However, that won't work with the stack currently in debian and since secret-project later installs that version of stack and runs it against the same stack.yaml file, I can't commit that change until Debian gets around to upgrading haskell-stack

Asked the stack developers and found a stack.yaml that I think worked with both versions of stack. At least both can build with it, have not tried running secret-project again.

Clean build

Yes, with the updated stack.yaml I do get a clean build upon stack build.

Yeah
