我在Xcode的other linker flag里增加了-ObjC -all_load后,编译cocos2d-x项目,提示错误:
duplicate symbol _SHA1 in:
/Users/Jack/workspace/cocos2d-x-2.2.1/external/libwebsockets/ios/lib/libwebsockets.a(sha-1.o)
/Users/Jack/workspace/cocos2d-x-2.2.1/cocos2dx/platform/third_party/ios/libraries/libcurl.a(sha1_one.o)
ld: 1 duplicate symbol for architecture i386
clang: error: linker command failed with exit code 1 (use -v to see invocation)
请问这个问题应该怎么解决?
