I am having trouble with the initial build. I think Qt, CMake, and Git are installed correctly. However, with Visual Studio, the instructions provided say “when configuring the installer, enable installation of Visual Studio 2019 (v142) toolset and component Programming languages / Visual C++ / Common Tools for Visual C++ (in some distributions, this option is not enabled by default)”. However, I do not see any option to select/install “component Programming languages / Visual C++ / Common Tools for Visual C++”, and I haven’t discovered anything online. I am unsure if this is related to my build failure but wanted to address this issue first.
The toolsets are optional things to install as part of the Visual Studio installation. In the Visual Studio Installer it looks like the following. I’ve highlighted the areas where you can select various toolkits.

Okay I included that one item checked off (MSVC v142 -VS 2019…) at the top in the installation process.
I am able to run this command without error -
“C:\Program Files\CMake\bin\cmake.exe” -G “Visual Studio 16 2019” -A x64 -DQt5_DIR:PATH=C:\Qt\5.15.0\msvc2019_64\lib\cmake\Qt5 “C:\D\S4”
The output is “Build files have been written to :C/D/S4D”
However, the second command yields errors and large output
“C:\Program Files\CMake\bin\cmake.exe” --build . --config Debug"
This isn’t the full output but some of the errors include:

I thought perhaps it was a proxy issue given that “no such host is known”. However, I don’t believe that to be the case. Thanks.
I have noticed other failures in regards to git. Here is some of the output.

In addition, here is a line from the output regarding skipping the compiler and not sure if this is relevant.

If anyone has any suggestions or insight into what the issue could be, I would appreciate it.
Thanks again.
These are all networking errors. Do you use VPN or corporate or hospital firewall to connect to the internet? If yes, follow these instructions.
I’ve moved past the networking errors (I believe). However, there is no “slicer.exe” file in my Slicer-build folder. Was the build not successful or am I missing something? I noticed there is a “SlicerPython.exe” in the “python-install\bin” folder
Note - there is a “slicer.exe” file in the “Program Files/Slicer 4.10.2” folder
Yes, you are expected to have a c:\D\S4R\Slicer-build\Slicer.exe file, which launches Slicer. If you don’t have it then it means that the build failed. Restart the top-level build and check for build errors.
- Are these below actual errors? And if so, what is their significance?

Also - it appears that I am getting LibArchive errors that are also present in a post that another individual had been receiving. So I can try that approach listed there.

Throughout the output I am seeing a lot of “not found” (below are just some of the few to give an example) and also some failed tests.

Are these “not found” indicative of a problem? Should there be zero “not founds” during the build? Or are they akin to warnings as opposed to errors?
Thanks again
None of these are errors. The Failed and not found messages are results of compile tests, which test features of the build environment. Errors are those that Visual Studio compiler reports as errors. You can show list of errors in Visual Studio menu: View / Error list.
Should I be opening the solution file in Visual Studio and building from there? I haven’t opened Visual Studio yet for this.
I was using the command line steps from the instructions:

@jrl What are your plans for development using Slicer? Are you planning to develop a new module? Customize a current module? Or just use python to code some commonly repeated steps in a workflow?
Develop a new module
A C++ based module or python? Have you tried out some python coding of various Slicer actions in the Slicer python interactor yet?
