无法编译需要C99编译器（AFAIU）的pyethash python包。错误 - 无法打开包含文件： 'alloca.h'

Question

问题

当手动或使用PIP我得到相同类型的错误安装pyethash：

fatal error C1083: Cannot open include file: 'alloca.h': No such file or directory error: command 'C:\Program Files (x86)\Microsoft Visual Studio 9.0\VC\BIN\amd64\cl.exe' failed with exit status 2

相关和已经尝试过：

• error: Unable to find vcvarsall.bat
• Errors while building/installing C module for Python 2.7

类似的问题没有答案：

• comment42289832_26127562
• Setup script exited with error cl.exe' failed with exit status 2

其他事实：

• 成功安装加密和scrypt需要C++编译器。
• 有在pyethash core.c源文件头提到的另外3个文件，这是我的硬盘上的任何地方缺席：
  • alloca.h
  • stdint.h
  • stdlib.h中

问题

我如何编译这个包？ （请帮帮忙，这是第4天了！）

Answer 1

alloca页头茨一个 utomatic存储器和延Gustedt指出的不规范。

MSVCRT在<malloc.h> header中声明它。它在Windows上的实现与UNIX系统上的常见行为一致，因此它应该按预期工作。代码的其他部分可能与UNIX更紧密地耦合，可能需要重写。

另外两个头文件是标准C头文件，应该在您的编译器自动搜索的INCLUDE目录中。
