Delphi 2009 using MSBuild in RAD Studio Command Prompt F1026 File not found

I have been struggling to get the MSBuild to successfully build my .dproj file for the last few days on a build machine.

First, I needed the EnvOptions.proj file from the developer's machine, which got me clear of the missing system.pas file, but now I am getting a compile error for a missing .dcu

C:\Program Files\CodeGear\RAD Studio\6.0\Bin\CodeGear.Delphi.Targets(123,3): error : myproject.dpr(17) Fatal: F1026 File not found: 'mymissing.dcu'

Now the path to "mymissing.dcu" is included in the Win32BrowsingPath of the EnvOptions.proj file, and I tried adding the path to the command prompt PATH which also does not work.

If I copy the .dcu directly into the working directory it can be found - but this is not much of a long term solution,开发者_运维知识库 as there are many other .dcu files that I would need to copy into the working directory.

Any ideas?

Try <DCC_UnitSearchPath> in your .dproj file.

Make sure that all the environment variables referenced in library search paths, e.g. $(BDS), are actually present in the environment of the command prompt.
