@dbest10 i agree with you



I know that today, the new version of the curl come out.
New curl is applied cocos version is come out?
Because Ipv6 issue, I have not yet released the app.


@GwangSeok as you can see here, new version is not released.


curl is already released, when will the cocos version comes out?


v3.13 will be release on Aug 22. But i will upgrade CURL soon, then you can replace it.


iOS, Mac and Android are upgraded to v7.50.0 in


@GwangSeok could you please have a try?


I got an error “size of array ‘curl_rule_01’ is negative”

I still use cocos v2


@x10ng how does the error happen? I think CURL is cocos2d-x version free.


it happens on compile time, I don’t really know what’s wrong


Hey there. I updated the 3rd party libraries and resubmitted the app. It was rejected due to not supporting IPV6.

@dbest10 but i don’t change the compiling flags, just upgrade the version. And as you can see the compile flag, IPv6 is enabled, and in curl.h, curl is enabled too. You can set up your environment to test it according Apple’s doc.

And i can’t find the reason according the crash log. In your game, does only use CURL that is network related?


I only use cocos2dx and sdkbox. I have a feeling that the error is due to a game center call based on SDKBOX Play.


Did you use CURL yourself? cocos2d-x doesn’t uses CURL on iOS anymore.


I try to upgrade the version I have.
Doing so can I pass on its normal policy?


@fafriday i think you can just update CURL, if you meet compiling error, may be CURL break compatibility. Current CURL version is 7.50.0.

@slackmoehrle any update of you re-submit?


upgrade curl 7.50.0 version.

but i’am meet other error.

“Manifest.cpp” file.

No member named ‘MemberEnd’ in ‘rapidjson::GenericValue<rapidjson::UTF8, rapidjson::MemoryPoolAllocatorrapidjson::CrtAllocator >’; did you mean ‘MemberonEnd’?

No member named ‘MemberBegin’ in ‘rapidjson::GenericValue<rapidjson::UTF8, rapidjson::MemoryPoolAllocatorrapidjson::CrtAllocator >’; did you mean ‘MemberonBegin’?

What should i do ?


CURL is nothing related with rapidjson. Did you update other libraries too?


sorry… I did not check properly.

error is this.

i using cocos2d-x 3.12 version.

and i update cocos2d-x-3rd-party in curl forder and websocket forlder.

but, "AssetsManager.cpp"
No matching function for call to 'curl_easy_setopt’
No matching function for call to 'curl_easy_perform’
No matching function for call to ‘curl_easy_cleanup’

please. what should i do ?


@fafriday AssetsManager.cpp doesn’t use CURL, are you sure you uses v3.12?
