c++ - CMake 编译失败

Question

我正在尝试在 openSUSE 13.2 上编译 cocos2d-x 3.5，但在 .log 文件中出现以下错误:

Determining if the pthread_create exist failed with the following output:

我手动安装了依赖项和库，但仍然出现此错误。有谁知道这是怎么回事吗？

注意:当我尝试编译时，前两行是:

~/android-dev/cocos2d-x-3.5/cocos2d-x-3.5/build/linux-build> cmake ../..
CMake Error at CMakeLists.txt:35 (cmake_policy):
  Policy "CMP0054" is not known to this version of CMake.

谢谢:D

已解决，我只是在 CMakeList.txt 文件中注释了这一行

#if(CMAKE_VERSION VERSION_GREATER 3)
    #cmake_policy(SET CMP0054 NEW)
#endif() 

但是现在，当我使用 make 命令(无论在哪里，使用 NetBeans 或终端)时，它以 98% 的错误结束(大约 15 分钟编译后)

[ 98%] Built target cocos2d
[ 98%] Built target MyGame_CORE_PRE_BUILD

有什么想法吗？？

已解决，如果有人遇到同样的问题，只需使用带有参数 -pthread 的 cmake，然后您就可以使用 make 进行构建。如果你想使用 NetBeans 构建，你必须只保留 -G "Unix..."参数并在 CMakefile.txt 中添加以下行:set(-pthread) - 我确实在顶部添加了它 - 就是这样一切，应该一切都好 :D 干杯!
