lukexi / openvr-hs Goto Github PK

I tried building the test cases using cabal test. cabal test cubes didn't work either.

I managed to get as far as this output, after altering the cabal file for openvr-hs to point its extra include and extra library dirs at the spot where my OpenVR install was placed.

The resulting linker errors are below and relate to the functions VR_GetGenericInterface and VR_GetVRInitErrorAsEnglishDescription.

This may or may not be related to a separate problem: When I first tried to build the openvr-hs library, I ran into a complaint here in openvr_capi_fixed.h:

// #if defined( __WIN32 )
// typedef char bool;
// #else
#include <stdbool.h>
// #endif

Without the commenting-out, the compiler complains that bool is already defined, and it fails to even build, much less install, openvr-hs. But perhaps this is causing problems for the linker later on.

Advice?

After some cabal file hacking, I got around this I think. I'm having a different issue with linking, which I will post separately, which I hope you can help me resolve.

For the record, I just had to tell the gl library to accept a wider range of allowable dependencies for the directory library.

Hi! I'm just getting together the necessary tools and dependencies to try out your OpenVR/Haskell linkages. I think I'm almost there. I managed to build your lens-extra and linear-extra packages.

However, when I tried to build your gl-pal package, I encountered the errors below. I could fight with tracking down the offending library lines, but I thought I'd ask if you'd encountered this yet, and how to quickly fix it.

Looking forward to experimenting with Haskell based VR. :)
