Problems of windows compilation errors about seal-python HOT 20 CLOSED

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.

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

from seal-python.

Can you put screenshots? or more details?

from seal-python.

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?

from seal-python.

Can I speak Chinese with you？

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？

from seal-python.

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
   

from seal-python.

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～

from seal-python.

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。

from seal-python.

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。

嗯，自己总结下吧，确认没问题后记得关闭此issues。
