Build issues

Ninja build crashes with error 0xC0000005

When compiling using the Ninja generator, an error occurs during compilation.

ninja: error: exception: 0xC0000005
ninja: warning: minidump created: <path>

The .ninja_deps file in the CMake build folder is likely stale. Remove the file, and re-run CMake configure and generate steps.

No script engine for file extension “.js”

When configuring the project, a cscript error occurs.

Input Error: There is no script engine for file extension ".js".
...
ConanException: Error 1 while executing cscript configure.js ...

This is typically caused by .js file associations. The recommended fix is to reset the file association from the command prompt.

> assoc .js=JSFILE

Visual Studio Preview non-existing installation error

When configuring the project using a Visual Studio Preview version, the project fails to configure.

ConanException: VS non-existing installation: Visual Studio 17

Conan must be explicitly given the path to a Preview installation, otherwise it will only look for release versions.

> conan profile update conf.tools.microsoft.msbuild:installation_path="C:\Program Files\Microsoft Visual Studio\2022\Preview" default

Depending on your installation method, the path to your preview installation may vary (e.g., Community folder instead of Preview).
