hie-0.1.0.0 doesn't compile on windows 10 (due to text-icu-0.7.0.1)

[hanjoosten]

I am still on ghc 8.0.2 and unfortunatly currently not able to upgrade. I need hie to work with vscode. So I followed the installation instructions:

1. I cloned haskell-ide-engine into c:\hie
2. checkout branch hie-0.1.0.0
3. update the submodules
4. fire up a cli and fired the command stack --stack-yaml=stack-8.0.2.yaml install --extra-lib-dirs="C:\icu\icu4c-60_2-Win64-MSVC201" --extra-include-dirs="C:\icu\icu4c-60_2-Win64-MSVC2015\include"

I get the following error message:

C:\hie>stack --stack-yaml=stack-8.0.2.yaml install --extra-lib-dirs="C:\icu\icu4c-60_2-Win64-MSVC201" --extra-include-dirs="C:\icu\icu4c-60_2-Win64-MSVC2015\include"

    Cabal-simple_Z6RU0evB_1.24.2.0_ghc-8.0.2.exe: Missing dependencies on foreign
    libraries:
    * Missing C libraries: icuuc, icuin, icudt
    This problem can usually be solved by installing the system packages that
    provide these libraries (you may need the "-dev" versions). If the libraries
    are already installed but in a non-standard location then you can use the
    flags --extra-include-dirs= and --extra-lib-dirs= to specify where they are.

C:\hie>

It is obvious that there is something wrong with the missing libraries. However, that is why I give the switches --extra-lib-dirs="C:\icu\icu4c-60_2-Win64-MSVC201" and --extra-include-dirs="C:\icu\icu4c-60_2-Win64-MSVC2015\include". This is where these files are. I am not familiar with using non-haskell stuff. What could be wrong?

What is suspicious is the MSVC version of ICU. If you use precompiled versions, then MSVC import library format is incompatible with using GHC (which internally uses MinGW which is GCC).

I don't know how supported is that, but you can do the following:

• go to %USERPROFILE%\AppData\Local\Programs\stack\x86_64-windows\msys2-20150512\
• run msys2_shell.bat
• in the shell run pacman -Sy mingw-w64-x86_64-icu
• then it should run out of the box (i.e. without passing pathes anywhere)

If you run into troubles, e.g. if you use 32-bit GHC, you can do pacman -Ss icu to see the various icu-related packages available

Also test my instruction and report if anything is wrong with it :)

Thanks @nponeccop This really made my day. It works as a charm 😄
