msbuild verbosity is not passed to the Delphi command-line compiler any more, but for found units, you can use /p:DCC_OutputDependencies and for dfm/resource files /p:DCC_OutputDependencies

Posted by jpluimers on 2021/04/06

Last week, I wrote about msbuild verbosity levels. The post was both for my own documentation, but also out of need as I wanted to have way more verbose logging for a Delphi build process involving search path configurations.

When using my Delphi build script you can both pass msbuild options and Delphi compiler options:

Run-Dependend-rsvars-From-Path.bat 5 msbuild -verbosity:detailed "/p:DCC_OutputDependencies=true" MyProject.dproj

The bold one is the msbuild parameter, the italic one the Delphi compiler parameter for unit dependencies. They are directly passed to msbuild:

...\msbuild.exe /target:build /p:DCC_BuildAllUnits=true /p:config=Debug -verbosity:detailed "/p:DCC_OutputDependencies=true" MyProject.dproj

You can multiple options too:

Run-Dependend-rsvars-From-Path.bat 5 msbuild -verbosity:detailed "/p:DCC_OutputDependencies=true" "/p:DCC_Quiet=false" MyProject.dproj

In addition to unit dependencies, you can also get an overview of .dfm and other resource file dependencies by passing /p:DCC_OutputDRCFile=true on the command-line this will generate a DRC file that not just has all the resource string constants in it, but also a comment section specifying all resource files including these file types:

Both DCC_OutputDependencies and DCC_OutputDRCFile can also be set to true in a .dproj file and are configurable under two different project option paths:

  • DCC_OutputDependencies: “Project Options” -> “Delphi Compiler” -> “Compiling” -> “Output unit dependency information”
  • DCC_OutputDRCFile: “Project Options” -> “” -> “Delphi Compiler” -> “Linking” -> “Ouput resource string .drc file”

The -verbosity:detailed however, is not passed to the various Delphi DCC compilers, as somewhere along the line, the CodeGear.Delphi.Targets got changed to Quiet="true" somewhere in-between Delphi 2007 and Delphi 2010.

Delphi 2007 had from Borland.Delphi.Targets files containing from Quiet="$(DCC_Quiet)"; the file got renamed and changes likely in Delphi 2009. See these related posts:

This means as of then on, the DCC commandline compilers will always output non-verbose logging. Even specifying "/p:DCC_AdditionalSwitches=-Q-" will not help: you will just get blank lines.

In the past, one of the things the verbose DCC logging would help you to see which files where accessed using the actual build. This was a tremendous help when figuring out search path problems that kick in every now and then.

For units, there is a little trick you can use here: it’s the /p:DCC_OutputDependencies=true" option you see above.

It will output an additional file with the .d extension that:

  • on the first two lines are an empty line followed by lining having the the .dpr filenamea space and a backslash
  • continues with units in reverse order of dependency:
    • optional lines having two tabs, a full .dcu filename (even if the file was actually a .pas file), a space and a backslash
    • a final line having two tabs, a full .dcu filename (even if the file was actually a .pas file) but no space or backslash

That file is relatively easy to scan or parse for path problems.

Project settings

I am not sure at which Delphi version the depends feature became a project setting, but it is. The odd thing: it does not always work, at least not in the Delphi 102. Tokyo installations I have used.

In a .dproj file, it is inside this element: <DCC_OutputDependencies>true</DCC_OutputDependencies> just like the msbuild name.

In the UI, you can find it here:

msbuild verbosity levels

Posted by jpluimers on 2021/03/31

Passing verbosity levels to msbuild on the one hand can help to quickly locate issues that go otherwise unnoticed, but also make your output so large that it is hard to search through.

Some build targets (Delphi!) do not pass the verbosity to their underlying tools, so for those cases you have to find other means to increase underlying verbosity.

You can always pass msbuild options by using the commandline (even abbreviate them as described in [WayBack] MSBuild Command-Line Reference – Visual Studio | Microsoft Docs: You can specify the following verbosity levels: q[uiet]m[inimal]n[ormal]d[etailed], and diag[nostic]).

Often you also can use your IDE can also specify verbosity levels, for instance:

The currently specified verbosity values in ascending order according to [WayBack] LoggerVerbosity Enum (Microsoft.Build.Framework) | Microsoft Docs:

Quiet 0 Quiet verbosity, which displays a build summary.
Minimal 1 Minimal verbosity, which displays errors, warnings, messages with MessageImportance values of High, and a build summary.
Normal 2 Normal verbosity, which displays errors, warnings, messages with MessageImportance values of High, some status events, and a build summary.
Detailed 3 Detailed verbosity, which displays errors, warnings, messages with MessageImportance values of High or Normal, all status events, and a build summary.
Diagnostic 4 Diagnostic verbosity, which displays all errors, warnings, messages, status events, and a build summary.

Note that in the past, Detailed was called Details:

[WayBack] visual studio 2010 – What is output at the different MSBuild output verbosity levels? – Stack Overflow:

  • Quiet: only shows the result of your build.
  • Minimal: shows some configurations of your msbuild, and the CSC task.
  • Normal: This will show all the targets and its mainly steps.
  • Details: In addition to normal, this flag shows the task and it’s implementation within the each target.
  • Diagnostic: Contains all the information that a MSBuild need and produce, it’s switches, parameteres, prerequisites and etc. The input parameter of the target and task, and also contains the value of the input and output parameter, the detail steps of the task execution. The time execution for each task.

In matrix form, as per [WayBack] Obtaining Build Logs with MSBuild – Visual Studio | Microsoft Docs:

The following table shows how the log verbosity (column values) affects which types of message (row values) are logged.

Quiet Minimal Normal Detailed Diagnostic
High-importance Messages
Normal-importance Messages
Low-importance Messages
Additional MSBuild-engine information

Via [WayBack] Obtaining Build Logs with MSBuild – Visual Studio | Microsoft Docs:

If you need full debug output from msbuild, then append the -verbosity diagnostic parameter.

Like there was never an Office 13.0, there was no Visual Studio 13.0: see the below table from Microsoft Visual Studio – Wikipedia: History

This influences tooling that searches for specific versions of Visual Studio or MSBuild (which has been available since Visual Studio 8.0 and up: MSBuild – Wikipedia: History).
