Failure to compile cairo on macOS Sierra

[andreabedini]

I'm a newbie so I am not familiar with the whole stack. But I have this problem.

$ stack build cairo

gtk2hsC2hs: Error in C header file.

/usr/include/stdio.h:133: (column 19) [FATAL] 
  >>> Syntax error!
  The symbol `_close' does not fit here.

line 133 of stdio.h is

typedef struct __sFILE {
        ... omiss ...
        int     (* _Nullable _close)(void *);
        ... omiss ...
} FILE;

apparently _Nullable is defined in /usr/include/sys/cdefs.h.

I've got the same problem. Any ideas?

[loisch]

I don't have macOS Sierra. I only installed XCode 8.

[loisch]

I've found a workaround: I installed an old SDK from https://github.com/phracker/MacOSX-SDKs.

@loisch How did you make the build process point to the old SDK?

[agrafix]

@timbod7 you download the SDK and then SymLink it. The only annoyance is that you will have to rebuild everything...

[agrafix]

Btw the bug is probably something related to:

gtk2hs/tools/c2hs/c/CParser.y

Line 868 in b66eedc

-- parse C structure declaration (C99 6.7.2.1)

[hamishmack]

Sorry for the delay fixing this. It turns out this error only happens when building from clean. Fixed version of cairo (cairo-0.13.3.1) is now in hackage. Just uploading fixes for the other Gtk2Hs packages now.

@hamishmack Thanks for this. Switching to the new packages solved my issues with xcode 8.
