Thanks for trying OpenPetra on Ubuntu!
On Ubuntu, is NAnt installed to the GAC? I followed the instructions at nant.sourceforge.net/release/lat ... ation.html, and for Windows that means that NAnt.Core.dll is not part of the GAC. But I need that dll to compile the project csharp\ICT\PetraTools\NAntTasks\Ict.Tools.NAntTasks.csproj. That is the reason I put it into the git.
Ict.Common.DB should come from building "nant compileCommon", and that will run "nant compilePetraTools" already automatically, I think.
I recommend using nant over building from the solution files, at least the initial build.
Please let me know if you find more odd things, I hope we can resolve them quickly.
