Bug 21194 – VisualD cannot build unit-threaded_property.lib: saying corrupt MS Coff object

https://github.com/atilaneves/unit-threaded/issues/213 I got this error, when build with VisualD-v1.0.1-dmd-2.093.1-ldc2-1.23.0.exe dmd: lib\unit-threaded_property.lib: Error: corrupt MS Coff object module obj\debug\dummy\dummy\dummy\dummy\dummy\dummy\unit-threaded_property\..\..\..\..\..\..\Users...\AppData\Local\dub\packages\unit-threaded-1.0.4\unit-threaded\subpackages\property\source\unit_threaded\randomized\benchmark.obj 320 lib\unit-threaded_property.lib: Error: corrupt MS Coff object module obj\debug\dummy\dummy\dummy\dummy\dummy\dummy\unit-threaded_property\..\..\..\..\..\..\Users...\AppData\Local\dub\packages\unit-threaded-1.0.4\unit-threaded\subpackages\property\source\unit_threaded\randomized\package.obj 320 Building lib\unit-threaded_property.lib failed! (I didn't add package unit-threaded myself, guess it's indirectly pulled in by some other packages.) How to fix this Coff object issues? (BTW, why there are so many \dummy... dirs?) I just completely deleted that packages dir, C:\Users...\AppData\Local\dub\packages<all_the_dirs> and the <proj_dir>/.dub dir, and also the app.sln file; then I start from scratch: dub.exe generate visuald But I got the exact same build error: corrupt MS Coff object. I think it's showhow caused by the build process itself, maybe just inside the unit-threaded-1.0.4 package, any suggestions where to check further? I just tried, using -m32: /mnt/c/project/dlang/dmd-2.093.1/windows/bin/sc.ini [Environment] DFLAGS="-I%@p%....\src\phobos" "-I%@p%....\src\druntime\import" "-d" "-m32" at least that error is gone, and I was able to build: .dub/lib/unit-threaded_property.lib So, looks like this unit-threaded_property.lib cannot be build with -m64, but I just wonder why? I think this could be a VisualD issue. I cannot build with VisualD, but I can build on Windows using command line: C:\project\dlang\dmd-2.093.1\windows\bin64\dub.exe test --build=unittest

I suspect there is some mismatch with some part build with -m32 (OMF object files) and -m32mscoff (COFF object files). This shouldn't be an issue with -m64, though. unit-threaded itself does not seem to have this problem. Please provide explicit steps necessary to reproduce the issue (I don't know too much about dub).

I just tried: dub init dub add unit-threaded dub generate visuald and building the resulting solution works just fine. Are you doing something else?

Cannot reproduce. Please reopen and provide more information if it still happens for you.
