Problem with thread when porting game to windows phone 8

phuongitbk · May 17, 2013, 8:01am

Hi all,
I have a problem when porting game to windows phone 8. In project win32 I use pthread.h but it not working in windows phone 8.
And I find in CCTextureCache of core cocos2d-x, all variable and funtion related to pthread has been put in comment.
eg: in CCTextureCache.cpp
//static pthread_mutex_t s_asyncStructQueueMutex;
//static pthread_mutex_t s_ImageInfoMutex;
or:

//pthread_mutex_lock(&s_asyncStructQueueMutex);

How can i solve this problem?

I found wp8 use function in CCPThreadWinRT.h instead of pthread. It seems ok now. Any detail of function that you need?

How do you change HttpClient.cpp from pthread to CCPThreadWinRT?

Thanks!!!

You can simply use std::thread, transition is usually pretty straight-forward.

And I recommend C++ REST SDK (casablanca) as a replacement for HTTPClient.

but std::thread is not only for c++11? can I set c++11 in visual studio to compile my project and cocos2.2.3?

eh, but I have used HTTPClient in my android and iOS project… I want leave the same code… if is possible.

I tried include CCPThreadWinRT, but, what do you have inserted instead pthread_create, pthread_exit?

bye and thanks!!

Hi @lordubik, there is a pr about httpclient, libcurl, libwebsocket: https://github.com/cocos2d/cocos2d-x/pull/5098, I added some fix to let it auto-merged and will merged soon. And httpclient works well. Thanks.

Yes, it’s c++11 only. There is no switch to choose between c++ standards in VC, c++11 is default and only once since VC10.

I looked the HTTPClient changes and I have applied the changes… but pthread_create is a empty function:

define pthread_create(w,x,y,z) 1
define pthread_detach(x)

I have wrong something?

Thanks for help!!

yes I have taken the same code; but where is pthread_create? because inside CCPThreadWinRT.h there is a empty declaration…
I need httpclient for take a file from a website.

Thanks!

chenjc · March 21, 2014, 2:03am

@lordubik, it is not use pthread_create but use create_task to call sendRequest.

I think cocos v2 should create class thread for cocos. so, we can use same code for thread on all platfrom

chenjc · March 21, 2014, 3:17am

@dungmv @lordubik, do you use pthread function in your other game codes frequently? If so, Maybe we need to create implements for pthread function like pthread_create…

dungmv · March 21, 2014, 4:28am

yes. AI of game need multi thread

Hi, thanks for help me.
I don’t use pthread and createtask works well!

Thanks!

chenjc · March 26, 2014, 2:32am

@dungmv I replace pthread with std::thread and test ok, using macros.

dungmv · March 26, 2014, 4:28am

thank you
