Problems of windows compilation errors

[molimolihon]

I pull the code down from GitHub and follow the steps.When I run the ‘python3 setup.py build_ext -i’，it shows some errors like C2059,C2334,C7586.And when I run the python script , it shows me 'No module named ‘seal’ '.And my compilation environment is Windows VS Native2019 x64.Please give the advice, thank you！

Sorry, for some reason(may caused by the latest VS 2019 building requirements), you need to update to pybind11-2.6.1, I will commit it later.

[molimolihon]

I have updated to pybind11-2.6.1 ，but it also shows the same errors

[Huelse]

Can you put screenshots? or more details?

[molimolihon]

My environment is win10 vs2019+python 3.6.8 ，a new version. And I want to say what's the version about release ?3.4.5?or 3.3.2.1?

[molimolihon]

Can I speak Chinese with you？

[Huelse]

Obviously, you didn't reference the pybind11-2.6.1 successfully.
Please check out your native files /pybind11.
You will get the obj named like seal.cp37-win_amd64.pyd if compile well, and paste it into the tests and run.

可以打中文，只是用英文更方便后来者参考。

I need to run the ‘setup.py’ at first ,and then i may get the obj named likeseal.cp37-win_amd64.pyd.But now I can't run the 'setup.py'

看上面的报错，应该是没有把pybind11-2.6.1引用成功，所以不行。

我都是按照步骤操作的，请问这个问题可能出现在哪个环节呢？

报错在哪里问题肯定就在那里啊，你是怎么替换pybind11的？2个版本的pybind11.h的837行内容完全不一样。

现在提示这个：
warning LNK4098: 默认库“MSVCRT”与其他库的使用冲突；请使用 DEFAULTLIB:library

重新跑了一次又报这个错误：

这个报错信息也很清楚啊，你重新按要求编译就行了，实在不行就全部删了重来。

您重新拉下来跑是没问题的么？请问是什么系统平台环境？

[Huelse]

就win10或者ubuntu,python任意版本都可以啊

1. generate the seal.lib
   
2. pip install numpy or pip install -r requirements.txt
3. python .\setup.py build_ext -i
   
4. copy the seal.<version>.pyd to the tests and run
   

[molimolihon]

我的步骤跟您的一样，环境也一样，您这个是在本地跑的还是在这个git上拉下来跑的呢？我看目录好像不太一样～

[Huelse]

和目录没关系，我就是复制了git仓库一份到新建的tests文件夹里给你演示了下。
你看不懂报错吗？这个和目录没关系的，目前我看到的就是你的pybind11有问题，或者编译器问题。
这种自己环境上的问题请自行解决。

[molimolihon]

问题解决了，之前只是分别pip 了requirements里面的内容，但是不是pip install -r requirements.txt这样操作的，不知道问题出在了哪里，但是现在解决了。谢谢您。

[Huelse]

嗯，自己总结下吧，确认没问题后记得关闭此issues。
