Hi all,
I am the author of FLTKHS (http://github.com/deech/fltkhs) which aims to make it easy to install, write and deploy a native GUI application in pure Haskell. It is already able to build static executables on Linux, *BSD and OSX (Yosemite & El Capitan).

However a smooth GHCi experience across platforms is still lacking due to some outstanding issues that I am unable to figure it out. I have written up the issues in the documentation [1]. I could use some help specifically with running a REPL with a C++ shared library in GHC 7.10.3. It works fine in 7.8.4. This is documented in the section titiled "GHCi (Linux, *BSD & OSX Yosemite)" in the link below. There is also a mysterious GHCi error on Windows that I can't seem to figure out. It is documented in "GHCi (Windows only)" section.

Any help or pointers are appreciated.

Thanks!
