我的程序（QT / C ++）使用python模块从谷歌驱动器下载一些视频，它的工作非常好，但我无法交叉编译它为覆盆子pi3。我是QT Cross Compile for raspberry的新手，我无法在任何地方找到此错误的解决方案：
#define _POSIX_C_SOURCE 200112L

基于这个问题的解决方案Python compilation error: "LONG_BIT definition appears wrong for platform"。我在lib / python2.7 / Include / pyconfig.h中改变了这行#define SIZEOF_LONG 8再见这行#define SIZEOF_LONG 4（解释：'4为32位，'8'为64位）。
但现在我有一个我不明白的新错误:::

任何人都可以这个错误是什么意思???
