Aiding reproducibility in builds with MS Visual C++

<AdditionalOptions>%(AdditionalOptions) /d1trimfile:”$(SolutionDir)\”</AdditionalOptions> In your .vcxproj file or a Directory.Build.props when passed to the compiler (cl.exe, ClCompile) this should trim the leading path used for __FILE__.

Posted on 2023-01-23 by Oliver

Alright, I’ll admit it it: I am in team WinDbg. Sure, I’ll happily use WinDbgX — the “Preview” version of the “new” WinDbg which has been in preview for ages now — but I always was a bit unhappy with … Continue reading →

dumbin.exe, editbin.exe, lib.exe …

Posted on 2023-01-05 by Oliver

They’re all just slim wrappers around the actual link.exe, not using a common DLL or so, but actually invoking: dumpbin.exe simply invokes “link /dump” and failing that “link.exe link /dump” editbin.exe simply invokes “link /edit” and failing that “link.exe link … Continue reading →

Changing local Git clone from master to main

Posted on 2021-11-30 by Oliver

I never understood why Git chose master as the default branch name, MAIN in CVS seemed more sensible, but perhaps Torvald’s animosity towards CVS and SVN plays a role. Presumably trunk in SVN is a reference to the tree-like structure, … Continue reading →

So you have a WTL project but it’s not a COM server you’re writing?

Posted on 2019-09-11 by Oliver
