Dear List -

I'm working to get a package of mine that was archived last year back on to
The epanet2toolkit provides an R interface to the EPANET simulation engine
that is written in C.

The latest development version of the package builds and checks ok on mac
and linux but fails to
compile and install on windows with a bunch of errors like:

undefined reference to `_imp__*`

where * is some function defined in a header file and implemented in the
corresponding source file.

Am i missing a compiler flag or something?

Current output from winbuilder :
or https://pastebin.com/8JQNpNKp

source code: https://github.com/bradleyjeck/epanet2toolkit/tree/v22dev

Any insights appreciated.
