Failure to compile on OSX El Captain about cuda

[tmcdonell]

Thanks for the report. I haven't had a chance to upgrade to El Capitan yet. I'm travelling the next few days, but will try and have a look soon.

In the meantime you could try copying the cuda.buildinfo.generated file to cuda.buildinfo and see what extra flags are needed to get it to compile.

@tmcdonell thanks, I will try. I am not sure what's going on here. __WATCHOS_PROHIBITED is a macro defined in Availability.h but it doesn't seem to get expanded if I do gcc -E -I. -I/usr/local/cuda/include ./Foreign/CUDA/Runtime/Exec.chs.h.

...

ahhh

cbits.h does some patching around OSX macros, most likely it doesn't handle the new macros for WatchOS

/*
 * We need to work around some shortcomings in the C parser of c2hs by disabling advanced attributes etc on Apple platforms.
 */
#ifdef __APPLE__
#define _ANSI_SOURCE
#define __AVAILABILITY__
#define __OSX_AVAILABLE_STARTING(_mac, _iphone)
#define __OSX_AVAILABLE_BUT_DEPRECATED(_macIntro, _macDep, _iphoneIntro, _iphoneDep)
#define __OSX_AVAILABLE_BUT_DEPRECATED_MSG(_osxIntro, _osxDep, _iosIntro, _iosDep, _msg)
#endif

preprocessing seems to work removing that block entirely but building still fails. I'll report back.

EDIT: it builds correctly on El Captain without that block. Perhaps now c2hs has removed the shortcomings mentioned in the comment above?

[andreabedini]

yep, according to haskell/c2hs#85 the workaround is not needed anymore

[tmcdonell]

Ah, great! I have removed that block so hopefully all is good now. I haven't tested on El Capitan but it at least works on Yosemite.
