Re: [Haskell-beginners] Missing C libraries on windows

note that they also add extra-libraries: so that's also worth adding. On 7 May 2015 at 11:35, Elise Huard wrote:

Hi Cameron,

which error message do you get? I've hacked my way through such issues by manually adding an extra-lib-dirs: with the _absolute_ path in the executable or library section of the cabal file, so that could be something to try. It's not a final solution obviously, but it would allow you to check whether it works at all. An example on github of this https://github.com/nikki-and-the-robots/nikki/blob/master/src/testsuite/test...

I'm not sure if this is the right place for this, but I've repeatedly run into issues when installing packages through cabal. It complains about missing C libraries and then explains that I can solve the problem by "installing the system package that provides this library". This has never worked for me and so I assume I'm not doing it correctly.

For example, I am currently trying to install ftgl. Using --extra-include-dirs and --extra-lib-dirs to point at the lib and include of the c source folder of ftgl doesn't seem to work. Neither did putting the dll's in the path.

The tutorial linked from the wiki:[https://noamlewis.wordpress.com/2012/12/16/cabal-install-ftgl-on-windows-and...]

also doesn't work for me. And so I was wondering if anyone has had more recent success with that library and more generally if there were any suggestions as to what I might be doing wrong.
