Join them; it only takes a minute: Sign up Trying to use size_t in an Android NDK project up vote 0 down vote favorite I'm compiling an Android C++ project using android-ndk-r8e, and am getting an error: "Type "size_t" could not be resolved." Here's my code: #ifndef RESOURCE_H #define RESOURCE_H #include #include #include using namespace std; class Resource { public: Resource(android_app*, const char*); const char* getPath(); bool open(); void close(); bool read(void*, size_t); private: const char*path; AAssetManager* assetManager; AAsset* asset; }; #endif I'm guessing I'm missing an include, but I can't figure out what it is, and googling has been no help. Anyone have any advice? Thanks! c++ android-ndk include size-t share|improve this question asked Jun 4 '13 at 0:50 John Hansel 63 Did you try to swap and ? Maybe the Android header is doing something weird and redefining something. Also, you should not be using using namespace std; in header files, it is mostly considered as bad practice. –jcxz Jun 4 '13 at 1:16 Still doesn't work unfortunately... thanks though. Also thanks for the note about using namespace std, I guess the alternative is writing std::size_t (once I can get size_t working...)? –John Hansel Jun 4 '13 at 1:19 hm, sorry, then I am of no more help here. I do not use Android NDK, this was just a thing that popped into my mind, so I wrote it. One more idea I have, is to run your header file through C preprocessor. This way you could see, whether size_t gets defined or not, which would exclude any header file problems ... –jcxz Jun 4 '13 at 1:30 Please paste the compiler output. Which line does it complain about? It may also be useful to run ndk-build V=1 to see how exactly the compiler is invoked. –Alex Cohn Jun 4 '13 at 9:14 I think this is solved, it work for me. check sta

Without that it would be difficult to understand. If u have VS editor, try to run same on that as well. This will help u to identify whether it is coming because eclipse editor or not as u mentioned in your question. –Nipun Jul 3 '14 at 10:44 | show 3 more comments 1 Answer 1 active oldest votes up vote 1 down vote You're missing include an in your second.cpp file. Try to add i.e.: #include in this file. Then size_t should be resolvable. The header files within size_t is defined are the following: See also: here In case you don't use using namespace std; you have to write std::size_t though. If you want size_t in your global namespace, you can include instead - but I would advise against it, because it's deprecated and pollutes the global namespace. share|improve this answer edited Jul 3 '14 at 11:01 answered Jul 3 '14 at 10:41 Constantin 4,41084080 MSDN says STDDEF.H for size_t –Nipun Jul 3 '14 at 10:46 stddef.h is deprecated in C++, because it places each name in an global namespace. It's better to use instead. See also
