libuv doesn't build in VS2017

[RikVerbrugge]

I am running Windows 10 Creative Update with VS 2015 update 3 and latest versions of cmake and git. But every time I try to build the SDK on Windows 10 I get these errors:

   "C:\tmp\azure-iot-gateway-sdk\build\azure_iot_gateway_sdk.sln" (default target) (1) ->
       "C:\tmp\azure-iot-gateway-sdk\build\proxy\modules\native_module_host\native_module_host.vcxproj.metaproj" (defau
       lt target) (29) ->

       ) (46) ->

       sdk\build\core\gateway.vcxproj]

I have created several clones on different machines, but every time the same error. The directory where the libuv.lib should stay is also empty. I did a build --rebuild-deps, but got the same error

[zafields]

Can you specify exactly which versions of git and cmake you are using, so we can reproduce your error?

[fedeoliv]

I'm getting the same issue, using git (2.12.2.windows.1) and cmake (3.8.0).

[zafields]

@fernandoBRS Can you also supply your version of Python? I will setup a VM and try to reproduce your error.

[fedeoliv]

@zafields My python version is 2.7.13. Seems that it's not installing libuv. I needed to copy the libuv.lib to the folder "build_libuv\dist\lib" at the right moment in the build to make it working.

[zafields]

Interesting. That copy is supposed to be happening right here.

[zafields]

I think I found the culprit...

azure-iot-gateway\tools\build.cmd
...
Cloning into 'libuv'...
Checking out files: 100% (351/351), done.
Switched to a new branch 'v1.11.0'
Warning: Visual Studio not found
...

I'll have an answer shortly.

[zafields]

vcbuild.bat from libuv does not currently support Visual Studio 2017. I have created an issue on libuv, and I am looking for a fix.

To work around this issue, you can call the build script with the --disable-native-remote-modules switch and you should be able to build normally.

[fedeoliv]

@zafields now it's working when I add --disable-native-remote-modules. Thank you!

[zafields]

@fernandoBRS They almost have the fix in place in libuv, to check status watch this issue -> libuv#1284: build: make libuv buildable with vs2017.

Once it is merged in and versioned, then we will start pulling it in.

Thanks for spotting this!

Hello,
I am using Windows 10 - 64 bit
Visual Studio 2017 Community (for student)
Python v3.6.0
CMake v3.8.1

I tried to build with tools\build_dotnet.cmd - this builds no problem
Again I faced the same issue that @RikVerbrugge has faced above for the clone I did last week (4-5 days before), I wonder if this issue has been fixed yet in Azure IoT Edge SDK project here?
I then did tools\build_dotnet.cmd --disable-native-remote-modules it builds (not sure what I exactly had happened under the cover). However, it gave me 39 Warnings, I am now worried why these warnings came at all. Please see the Warnings below:

1. The output you provided looks like it came from running tools\build.cmd, not tools\build_dotnet.cmd. Can you confirm?
2. You can get rid of the PDB warnings by adding the --rebuild-deps command, e.g.:

tools\build.cmd --disable-native-remote-modules --rebuild-deps

[zafields]

Also some of our configurations require Python2.7 instead of Python3.6
