Linux 64 bit not working

[urs-of-the-backwoods]

HGamer3D Linux is not working (at least also not tested) on Linux 64 bit

[deepfire]

What is the way to debug that, for somebody who can run GDB/strace, but other than that has no experience in Haskell FFI debugging?

My assumption would be that somewhere in the process of creating bindings and compiling them there might be a 32/64 bit missmatch, but this is not secured it is just a vague idea. The process of going into the details of the bindings is pretty involved, some small hints here: http://www.hgamer3d.org/BindingToolchain.html.

Today I tried to start myself wth Ubuntu 14.04, 64 bit, but Ogre 1.8.1 does not compile on it (could not find Freetype although it is present). Working on it.

In branch "feature-64bit" you can find a fix, which makes Graphics3D and Ogre Bindings runnable on 64 bit ! Since it is not in the main branch and on hackage, you need to compile HGamer3D-Data and HGamer3D-Graphics3D manually, by entering the respective directories and applying scons. In additions the Ogre bindings needs to be re-build. It has been tested on Ubuntu 14.04 LTS 64 bit successfully. The BlueCube example works.

Note: the other bindings still needs to be tested.

How to debug: you can use ghci to debug HGamer3D. There are a few things to note, before this works:

• start GHCI the following way "LD_LIBRARY_PATH=~/.HGamer3D/lib ghci -i../Graphics3D"
• in ghci load graphics3d and your example, like ":load HGamer3D.Graphics3D Graphics3D/BlueCube.hs" (assumed you are in Examples folder)
• before starting ghci copy Examples/build/.HGamer3D/config/* to ~/.HGamer3D/config, this is neccessary since FindBin does not find the executable in ghci and the second alternative to look for config files is ~/.HGamer3D/config but it needs to be populated

With all that, you can debug in ghci with :trace, :list, :step and so on.
