Error when trying to setup Ultimate ALPR on windows server

[Patrik Gillebo Olsen]

Hello. When trying to build Ultimate on our two Windows Server OS, we encounter an the same error message. Are you familiar with how to fix this issue?

The error message:

Hello,

Check https://stackoverflow.com/questions/40018405/cannot-open-include-file-io-h-no-such-file-or-directory there are several propositions on how to solve the issue.

You probably didn’t install all C++ dev components as explained at https://learn.microsoft.com/en-us/answers/questions/1386273/io-h-not-found.

- If io.h is under C:\Program Files (x86)\Windows Kits\10\Include\<version>\ucrt ,then make sure to ref the folders as per https://stackoverflow.com/a/56520573

- if io.h isn’t under …, then you haven’t installed all C++ comps

Very important: Do not reply to me but to douba...@googlegroups.com. Otherwise it'll go to spam and be deleted after 48hr. Also, no need to put my email in CC, otherwise I'll get it twice.

To clarify: this is *not* an issue in our product. You'll have same errors if you try to build any other python extension. It's important to clarify because it means you can google the error as well to try to get help from elsewhere.

This said, your dev env looks incomplete. 

Did you reboot your PC after installing MSVC?

The stackoverflow link I shared has multiple possible solutions, did you try them?

Did you install Microsoft SDK?

On my PC when I go to "C:\Program Files (x86)\Windows Kits\10\Lib" I have 2 folders: "10.0.10240.0" and "10.0.17763.0"

Same for "C:\Program Files (x86)\Windows Kits\10\Include"

"10.0.10240.0" is a slim version a has almost nothing in it while "10.0.17763.0" has all libs and headers.

From your logs the toolchain is using MSSDK from "C:\Program Files (x86)\Windows Kits\10\Lib\10.0.19041.0", make sure "10.0.19041.0" isn't a slim version and is the one you have installed.

You should not need to update the paths to have it working.

1/ Undo your changes.

2/ Look you're using MSVC2019. On the same console you're trying to build the extension; run "C:\Program Files (x86)\Microsoft Visual Studio\2019\Community\VC\Auxiliary\Build\vcvarsall.bat" to set all var envs

3/ Try to build the extension again. If it fails, then you'll have to re-install MSVC and  MSSDK and make sure you've selected all required comps. Then, reboot

Thank you, I did as requested, and added the paths to INCLUDE and LIB, and it got further. However, I met another error message. Maybe I'm missing other paths?. The error is as follows;
