Comment:
This isn't a GHC bug but an ImplicitCAD one. It's the result of me being
sloppy when merging someone's work into master: they created a file
(Graphics.Implicit.Export.TextBuilderUtils) and I forgot to add it to
ImplicitCAD's cabal file. Thus cabal didn't install that module and so
ImplicitCAD seems to install fine, but if you try to build something using
ImplicitCAD, part of it is missing and so it fails in linking.
If you look carefully at the error messages from ld, you'll see:
{{{
implicitzm0zi0zi2_GraphicsziImplicitziExportziTextBuilderUtils_zdwbuildTruncFloat_closure
Graphics Implicit Export TextBuilderUtils
buildTruncFloat
Graphics.Implicit.Export.TextBuilderUtils
(buildTruncFloat)
}}}
which is the missing file and exports a function buildTruncFloat.
You don't see this if you work in the ImplicitCAD folder because it uses
the local copy, so this didn't get caught earlier.
Sorry about any confusion and thanks for catching this bug!
