Building in Visual Studio

@terrajobst

From @terrajobst on Mar 26

On a clean machine, opening the solution file and building in VS fails as the Tools folder doesn't exist. Just running init-tools.cmd doesn't fix it either as it now fails with malformed AssemblyInfo.cs files.
I'm still trying to get build working from the command line (where I get mostly actionable error messages, like Install CMake) this feels like the sort of thing that discourages contributors quickly. Ideally, you should be able to clone the repo, open the solution in VS, and building immediately.
Thoughts?

The error message you got told you to run build from the root of the repo first, right?
This is the same experience as dotnet/corefx

The error message you got told you to run build from the root of the repo first, right?

Ah yes. Here is the error:

The tools directory [P:\machinelearning\Tools/] does not exist. Please run build in the root of the repo to ensure the tools are installed before attempting to build an individual project.

I missed the "please run build in the root". So I take it back -- the error we provide is actually actionable, provided the person can read properly :-)

This is the same experience as dotnet/corefx

Yes, but in corefx it's mostly because for us there isn't necessarily a good way to build from the IDE. Other projects (like Roslyn and ASP.NET) allow for developing/building inside the IDE. I don't see why ML.NET has to be a CLI only build experience -- they sit on top of the platform.

Other projects (like Roslyn and ASP.NET) allow for developing/building inside the IDE.

These projects don't contain native code. And even harder, building native code cross platform.

I don't see why ML.NET has to be a CLI only build experience

It isn't a CLI only build experience. It is a "build from the CLI first" experience. After you build once from the command-line, you can then use the IDE until your heart is content.

That's fair.

It isn't a CLI only build experience. It is a "build from the CLI first" experience.

I see. I got the impression that you always have to run the build.cmd from the command line. For the initial prep, do I have to run build.cmd or should it be sufficient to just run init-tools.cmd? If not, maybe we should move init-tools.cmd out of the root.

@eerhardt

@eerhardt can this issue be closed?

@maryamariyan

@maryamariyan once build.cmd has run from the root, is the VS experience on csproj and .vcxproj satisfactory? If so, yes. If not, please update the issue with the problem.

When you just open the .sln in Visual Studio and try to build with a clean repo, you get the error:

Severity	Code	Description	Project	File	Line	Suppression State
Error		The tools directory [F:\git\machinelearning\Tools/] does not exist. Please run build in the root of the repo to ensure the tools are installed before attempting to build an individual project.	Microsoft.ML.Core	F:\git\machinelearning\Directory.Build.targets	4

Once you run build.cmd in the root of the repo, you are able to build and test in VS as expected.

Closing.

In order to build in the Visual Studio IDE, need to call “build.cmd” from the command line first.

The last 2 errors about not supporting .NET Core 3.0 shouldn't block you from building. They can be ignored.

The first screen shot you posted with 1000 errors - are you still getting those?

What does the "Output" window say when you build?

when I run "build.cmd" then doing some process and then getting below error at the end.

we are getting below error in Cmake:

@Hiren161 - can you try the following?

Close all applications.
From a command prompt in the root of your repo (looks to be D:/Git/ML:

Does that succeed? If it fails, what errors does it print?

Yes, I have tried this any getting below error:

Is cmake on your %PATH%? From that same command prompt can you tell me what cmake --version outputs?

@eerhardt

The issue is finally resolved now. Many thanks to @eerhardt
Now, this is for reference for future readers who might come across this link.
We are using Windows-10. Though we have downloaded CMake, but we have not set into an "Environment variable => %PATH%". After setting it, we were able to build the whole app.

As a side note, during the build, if you get an error like -

could not find any instance of visual studio.

Then follow the below steps:
1). Open Visual Studio
2). Go to Tools -> Get Tools and Features
3). In the "Workloads" tab enable "Desktop development with C++"
4). Click Modify at the bottom right.

Hi,
I tried above steps but still unable to build the solution. CMake is added in %Path% variable. Below are the steps I followed.
-Closed all Visual Studio instance( using Visual Studio 2017 version 15.9.4)
-CMake version: cmake version 3.13.4

Ran git clean-xdf.
Ran .\build.cmd from root folder (C:\My Data.net sample code\MachineLearning).
Getting below error on build command

After checking the folder I can see code in src\Native folder didn't build.
Can anyone please help.

Just a shot a in the dark - but can you try a folder without a space in it? We've had issues with having spaces in the repo path before:

C:\My Data.net sample code\MachineLearning\

try

C:\MyDataSampleCode\MachineLearning\

Thanks Eric, the shot in the dark was right on spot.
Is the space in repo path obstructing CMake?

Is the space in repo path obstructing CMake?

Yeah, we probably have some build logic that isn't quoting the path correctly. CMake does support spaces in the path name, if you do it right.

#2925 is an example of fixing such a build logic error.
