Fails to build on Mac

[jenstroeger]

Today I wanted to build i3status from source because it doesn’t seem to be available from MacPorts (whereas i3 is, albeit not maintained).

So, following the instructions got me a few warnings and then

FAILED: i3status.p/src_print_disk_info.c.o 
cc -Ii3status.p -I. -I.. -I../include -I/opt/local/include -I/opt/local/include/yajl -fcolor-diagnostics -Wall -Winvalid-pch -std=c11 -O0 -g -Wunused-value -D_GNU_SOURCE -D_REENTRANT -MD -MQ i3status.p/src_print_disk_info.c.o -MF i3status.p/src_print_disk_info.c.o.d -o i3status.p/src_print_disk_info.c.o -c ../src/print_disk_info.c
../src/print_disk_info.c:138:16: error: use of undeclared identifier 'path'
    if (statfs(path, &buf) == -1)
               ^
1 error generated.

and it seems the __APPLE__ code is the culprit:

i3status/src/print_disk_info.c

Lines 135 to 141 in 30ea2d2

	#if defined(__DragonFly__) || defined(__APPLE__)
	struct statfs buf;
	if (statfs(path, &buf) == -1)
	return;
	mounted = true;

Changing path to ctx->path compiles and seems to run:
