Installing rvo2 for windows

[pedroveloso13]

I have the following problem when I try to build or install. Apparently, everything works well until it tries to build the rvo2 extension:

Can you post the entire output of the build? Also, please place it between triple backticks to mark it up properly (I've done that with your first post as an example of what I mean, click on the little "edit pencil" to see it).

[pedroveloso13]

Any suggestion?

[sybrenstuvel]

I don't develop on Windows, so I have hardly any experience there. Since it can't find RVO.lib, I would suggest following that lead. See whether the file actually exists (but in a different location than expected by the build script) or whether it doesn't exist at all (and in that case, which files of a similar nature do exist).

[Dostoyewski]

I have the same problem. But when I added in appveyor.yml line '- Visual Studio 2019', error LNK1181 disappeared. Yet I have another problem - error LNK1112.

[ZC119]

@Dostoyewski Did you solve this problem? I can't install on Windows either. Could you give me some advise?

[Dostoyewski]

No, the problem is not solved. I use this version of RVO2: github.com/jimfleming/rvo2

你好，你是怎么解决的，我遇到了相同的问题，求教

i got the same question;and i found the RVO.lib in the directory 'F:\python_program\Python-RVO2\build\RVO2\src\Debug', along with 'RVO.pdb'.so in this situation,how to solve this problem?thanks

I found it too，and I changed the "library_dirs=['build/RVO2/src']" to "library_dirs=['build/RVO2/src/Debug']",but it didn't work.
Have you solved it？Can you give me guidance if you solve it?

[Dostoyewski]

@Dostoyewski Did you solve this problem? I can't install on Windows either. Could you give me some advise?

No, i have installed it on WSL with Ubuntu 18.04.

refer to this link: https://juejin.cn/post/7297130301289332771
find the file RVO.sln (/build), change with release model to run and you can get the file RVO.lib (build/src/Release/RVO.lib)
copy this file to root directory (where setup.py and CMakeLists.txt is located)
in terminal to run python setup.py build and python setup.py install
