Scilab 2023 Xcos electrical demo does not work in Windows 10

Question

I've just installed Scilab 2023 in Windows 10 with Visual Studio Buildtools successfully:

--> haveacompiler()
 ans  =

  T

--> findmsvccompiler()
 ans  =

  "Visual Studio Build Tools 2022"

But when I try simulating Electrical Demo in Xcos, RLC, for example, this is the answer "

fatal error C1083: 'math.h': No such file or directory"

Can someone please help me. Thank you.

Answer 1

That may be due to a partial VS Studio installation. I suggest to select a msvc and maybe switch to a full Visual Studio installation.

On my machine, all works well with:

--> findmsvccompiler()
 ans  =

  "Visual Studio Community 2022"

Answer 2

I had the same problem when running a custom Xcos with electrical components.

As suggested by davidcl, I had to install more development packages in the Visual Studio Installer. More specifically, to avoid installing every packages,

1. Launch Visual Studio Installer
2. Click Modify
3. Under Workloads, select and install "Desktop development with C++"

Afterward, Scilab still dropped an error that seemed related to the PATH System variable. Uninstalling and reinstalling Scilab and rebooting my system fixed the issue for me.
