The still open question is how to generate the Haskell source without
writing into odd place of the file-system.

Can 'export_code' do that, with a slight modification to produce formal
exports via Export.export?

[isabelle-dev] System migration

2018-10-09 Thread Lars Hupel
Dear Isabelle developers and users,

we will perform a large-scala system migration over the next 24–48
hours. The purpose is to move towards the latest Ubuntu 18.04 LTS.

Affected will be continuous integration, the AFP, and the AFP submission
service.

Expect intermittent unavailability and HTTPS errors.

I will update as soon as the migration is completed.

Cheers
Lars

Compiling a binary in HLDE was a mere experiment on our side too. So I
also do not mind much to remove this again from the AFP.

I would however like to keep theory Solver_Code and still let it
generate Haskell source code (that is required for the handwritten Main.hs).

Then the task of setting up a proper Haskell environment and compiling
an executable is moved to prospective users. Which is fine with me.

cheers
