Question

我的程序（QT / C ++）正在使用python模块从Google驱动器下载一些视频，它工作得很好，但是我无法针对树莓派pi3进行交叉编译。我是树莓QT Cross Compile的新手，在任何地方都找不到此错误的解决方案：

 #define _POSIX_C_SOURCE 200112L

Answer 1

基于此问题Python compilation error: "LONG_BIT definition appears wrong for platform"的解决方案。我在 lib / python2.7 / Include / pyconfig.h 中更改了此行#define SIZEOF_LONG 8，并在此行{{1 }}（说明：“ 32位为'4'，64位为'8'）

但是现在我有一个新的错误，我不理解:::

#define SIZEOF_LONG 4

任何人都可以看到此错误的含义吗？
