7.python环境打包32位:nuitka、Cython使用WinGw32进行32位编译打包

---

前言

由于系统内部分电脑需要使用32位windows，导致平时64位系统打包都失效。
这个时候在64位环境换成32位，遇到一些问题（由于windows系统安装不了vs相关编译模块，不得已采用wingw替代），导致必须使用WinGw32进行打包。

准备清单：python 32位版本、winGw32，由于我采用nuitka进行打包，可以使用nuitka第一次打包提示下载的winGw32版本进行安装。具体配置看：
一文讲清nuitka打包
6.Cython使用WinGw编译pyd

---

需求：使用Cython把python单个文件编译位pyd文件

一、基础安装一笔带过

下载python32位版本、根据项目需求安装对应包；

二、Cython使用wingw32遇到问题

看到“C:\mingw64\bin\gcc.exe”这个一脸懵逼，实际我用到是32位，而用到了64位去；网上搜索很多解决办法。
其中比较关键的一句话,引起了我注意，与64环境的编译语句不一样

32位:
python setup.py build --compiler=mingw32
64位:
python setup.py build_ext --inplace -DMS_WIN64

我把调度语句改成32位的，还是一样的提示。为什么？

三、修改python内部调度，可行不？

这个可能可行，我看了一下代码，有点复杂。暂时放弃

四、昨夜思考改名怎么样

把wingw32改成wingw64，path配置也改掉，是不是就可以了？

测试执行“python setup.py build_ext --inplace -DMS_WIN64”提示不对；
测试执行"python setup.py build --compiler=mingw32"编译通过

需要验证：nuitka打包是否存在问题呢？如果存在，以后打包就比较麻烦，需要来回改路径名称 wingw32<–>wingw64

五、取余、取模符号不认识

编译pyd文件之后，调用提示：

ImportError: DLL load failed while importing py_dynamicEncryption: 找不到指定的模块。

看了下程序运行imort部分代码，再调用这个模块之前已经import过其他模块，由此可见，以上步骤是可以编译出可以运行的pyd文件的；
针对次文件进行问题点位，发现一行代码操作则不能够import进来:

salt = math.round(math.random() * 1000000000) % 100000000

解决办法：使用下面函数替代这个 % 符号即可import成功。

# 取模，Python中可直接用%，计算模，r = a % b
def mod(a, b):
    c = a // b
    r = a - c * b
    return r

# 取余
def rem(a, b):
    c = int(a / b)
    r = a - c * b
    return r
def test():
	#s = math.round(math.random() * 10000) % 10000
	s = mod(math.round(math.random() * 10000), 10000) # 具体使用mod还是rem自己验证一下
