Comet Build
Full solution build (Release x64)
& "C:\Program Files\Microsoft Visual Studio\2022\Community\MSBuild\Current\Bin\amd64\MSBuild.exe" `
"C:\Work\Comet-master\Comet.sln" /p:Configuration=Release /p:Platform=x64 /m /nologo /v:minimal
Show only errors and C4-level warnings:
... 2>&1 | Where-Object { $_ -match "error|warning C4" }
Building from WSL (Bash tool)
MSBuild.exe is directly invocable from the Bash tool in a WSL session on this machine (no
powershell.exe/cmd.exe wrapper needed) — Windows interop lets WSL bash exec .exe paths
under /mnt/c/... directly:
"/mnt/c/Program Files/Microsoft Visual Studio/2022/Community/MSBuild/Current/Bin/amd64/MSBuild.exe" \
"/mnt/c/Work/Comet-master/Comet.sln" /p:Configuration=Release /p:Platform=x64 /m /nologo /v:minimal
Use forward-slash /mnt/c/... paths (not C:\...) when invoking from bash. This means a WSL-based
Claude Code session can build and verify the Windows/VS side of a change directly, not just the
Linux make build — don't assume Windows-only code (e.g. /clr files, CometWrapper,
RealtimeSearch) is unverifiable just because the working shell is bash.
After building: copy the wrapper DLL
CometWrapper.dll must be manually copied after each build for RealtimeSearch.exe to pick it up:
Copy-Item "C:\Work\Comet-master\x64\Release\CometWrapper.dll" `
"C:\Work\Comet-master\RealtimeSearch\bin\x64\Release\CometWrapper.dll" -Force
Build targets and outputs
| Project | Output |
|---|
| MSToolkit | x64\Release\MSToolkit.lib |
| CometSearch | x64\Release\CometSearch.lib |
| CometWrapper | x64\Release\CometWrapper.dll |
| Comet | x64\Release\Comet.exe |
| RealtimeSearch | RealtimeSearch\bin\x64\Release\RealtimeSearch.exe |
To rebuild only CometSearch + CometWrapper (fastest for C++ changes):
... /t:CometSearch`;CometWrapper
RTS_TIMING instrumentation flag
Location: CometSearch\CometSearch.vcxproj, Release config <PreprocessorDefinitions>.
RTS_TIMING_OFF — production build (default)RTS_TIMING — enables per-spectrum printf("TIMING\t...") in DoSingleSpectrumSearchMultiResults
Always disable before benchmarking. With 40k spectra and 20 threads, the stdout contention from printf adds ~8 seconds to the search time and makes Hz numbers meaningless for comparison.
C# language version
RealtimeSearch\RealtimeSearch.csproj targets .NET Framework 4.7.2. Both Debug|x64 and Release|x64 configurations have <LangVersion>7.3</LangVersion>. Do not use C# 8.0+ syntax (e.g., using declarations without braces) without bumping this.
