Hi! I'm trying to use this - updated the icu4c version to 58.2, the php version to 7.0.20, and to no-debug-non-sts-20151012 . . .

I get this error:

In file included from /Users/adamdarby/intl-3.0.0/php_intl.c:25:
In file included from ./php_intl.h:34:
./intl_error.h:24:10: fatal error: 'ext/standard/php_smart_str.h' file not found
#include <ext/standard/php_smart_str.h>
         ^
1 error generated.
make: *** [php_intl.lo] Error 1
cp: modules/intl.so: No such file or directory

Any ideas? I'm running MAMP 4.2.

@kyds3k did you find solution?
