General Question How to configure VS to use single core?

[SpaceBoy2]

The instructions for building with the VS generator says to configure it to use single core. But how do I do this?

Thanks

To clarify, which instructions?

I can tell you for certain that both multithreaded compilation and multithreaded add-ons are possible.

I meant the build instructions for OpenOrbiter. I normally use Ninja so no problem. I asked the question out of curiosity, to see how you would do it to use the VS generator.

And what part of the code is not threadsafe? The integrator?

Thanks again

I have configured the VS generator to use multi-core build to greatly decrease build-time and it's been working just fine here. However, documentation build process could fail with multi-core. I have never tried to build documentation so far. If there is a problem then maybe the multi-core could be disabled if documentation build is enabled.
Multi-core build is enabled by "set(CompileFlags "/MP")" in CMakeLists.txt in the root folder.

Oh I see. Thanks for the information. But does that mean switching to single core is not necessary for building Orbiter? I have tried building with VS but it failed all the time so I thought it might be the configuration
P.S I never build docs too

Correct, no need to switch to single-core. Which part is failing ?

After building the Orbiter I have performed Install operation using "Tools/Command Line/Developer PowerShell"
like this "PS C:\Software\CleanBuild-VS> cmake --install C:\Software\CleanBuild-VS --config Debug"

The install destination must be configured when running the "CMake-GUI"

I forgot which part. Something related to CMake.
Thanks for that

Ah. I don't use CMake GUI now that I use to use Ninja. That might be it LOL

I succeeded in building it! Thanks. But I don't know what I did this time correctly. I still didn't use CMake GUI but used Ninja to set the variables and then switched to VS maybe that was it
