I use:
-Cocos2d-x 2.2.6
-Latest version of Smartfox C++ client
-Boost 1.55
-NDK r10d
-XCode 6
It's painstaking hard. MAYBE BECAUSE I AM NOT C++ EXPERT.
A lot of thing here and there to fix to get it working ranging from compiling Boost to work on both iOS/Android and correct version of C++ to get it compiled with ton of warning. With so many paths to explore and failed.
I have to change some Smartfox C++ client code to get it working.
The C++ sample(FullHouse) on Smartfox Download section used old version of C++ client which doesn't support Unicode and that cause me a lot of headache because my App need Unicode.
Thanks;
