DX12 SDK Samples compilation: error C2102: '&' requires l-value

This error:

error C2102: '&' requires l-value

Can be resolved by setting the flag:

Configuration Properties->C/C++->Language->Conformance Mode->No

Instead of Yes (permissive)

Feynman quote

 i will do something with this later:

The problem often is not people being uneducated.

The problem is frequently that people are educated just enough to believe what they have been taught, and not educated enough to question anything from what they have been taught.

—Professor Richard Feynman

fun with HLSL memory barriers

 Great description/clarifications on HLSL memory barriers:

D3D12ReportLiveObjects

 needed to use ReportLiveObjects, was getting compile errors on DXGI_DEBUG_ALL.

capturing for future debug:

dxguid.lib;nvapi64.lib;d3d12.lib;dxgi.lib;d3dcompiler.lib;kernel32.lib;user32.lib;gdi32.lib;winspool.lib;comdlg32.lib;advapi32.lib;shell32.lib;ole32.lib;oleaut32.lib;uuid.lib;odbc32.lib;odbccp32.lib;%(AdditionalDependencies)

This order of these libs worked. investigate later, hypothesis is the dxguid.lib before d3d12.lib perhaps?

Adding static libs to github repo, next steps

 Not sure if git got confused or I did something wrong. I had to do a clone of the repository after uploading some static libs. The libs are required as this was the distribution mechanism for the files. May have just been a one time thing but writing this down in case it happens again.

had to manually populate with the github web interface, couldn't use the github desktop. might have been a .gitignore setting that i just couldn't see the files, investigate later.

where DOS cmd

 Not sure where you have been all my life, but the DOS 'where' cmd tells me which .exe is being pointed to (for example) when compiling so i don't have to guess:

https://ss64.com/nt/where.html

for example, 'where fxc'.

disabling profiling in visual studio 2019

 

Disable in Options->Debugging->General->

Enable diagnostic tools when debugging.

Startup and shutdown of apps during debug is much faster, especially on remote debug scenarios.

Bodyguard treadmill maintanance

After lubricating the treadmill also have to go into a menu called 'maintenance' and reset the average current or it will not compute a current based on the new lubricated treadmill.

this is not documented as far as I can tell.

Use up/down arrow keys on right hand side to go through the diagnostics menu until you find the current test, then select reset average.
