error: no member named 'st_atim' in 'struct stat'

[ryandesign]

Hello, we have an old version of mg in MacPorts which I'm trying to update to your latest version 20180927. I'm trying to build it on macOS High Sierra.

First, it told me to install libbsd. I tried to build libbsd, but it failed. I reported that to the developers of libbsd. Then, since macOS is based on BSD, I tried patching your makefile so that it would not require a separate libbsd.

That got me further, and now it fails to build for me with this error:

fileio.c:282:20: error: no member named 'st_atim' in 'struct stat'
        new_times[0] = sb.st_atim;
                       ~~ ^
fileio.c:283:20: error: no member named 'st_mtim' in 'struct stat'
        new_times[1] = sb.st_mtim;
                       ~~ ^
2 errors generated.

I've run into this problem with other projects as well. Seems this is just one of those things that different operating systems do differently: macOS doesn't use the names st_atim, st_ctim, st_mtim, but instead uses st_atimespec, st_ctimespec, st_mtimespec.

Since the last release, I see you've added cmake support. Maybe you could have cmake detect which time fields to use on the current OS.

First hit on google for: “error: no member named ‘st_atim’ in” :-)

	#if defined(__APPLE__)
		new_times[0] = sb.st_atimespec;
		new_times[1] = sb.st_mtimespec;
	#else
		new_times[0] = sb.st_atim;
		new_times[1] = sb.st_mtim;
	#endif

I built this for iOS, encountered the same thing.

Hi there @blanxd,
thanks for your suggestion. Could you make a pull request out of that?

Cheers!

Just a heads up, this applies to NetBSD as well. In my port of mg I use the following in defs.h:

#if defined(__APPLE__) || defined(__NetBSD__) 
#define st_atim st_atimespec
#define st_ctim st_ctimespec
#define st_mtim st_mtimespec
#endif
