#749 Cannot Build 0.91 Alpha 2

[Jimmy Sieben]

I downloaded 0.91 Alpha 2 source and extracted to clean directory.
Using Visual Studio 2008 I ran nmake /f Makefile.nmake to try and build. However the bootstrap NAnt fails to run (see below).

I am on Windows 7 x64. I am able to compile 0.90 just fine on the same machine.

D:\SFNant091alpha2>nmake /f Makefile.nmake

Problem is that log4net references the System.Web assembly, and this one is not included in the .NET 4.0 Client Profile.

We need to either work with the log4net team to split classes tha depends on System.Web into a separate assembly, or remove the log4net dependency altogether.

[Jimmy Sieben]

Looks like there is already an open issue in log4net about this:

I had the same error, it seems I didn't had the "whole" framework installed. Just like drieseng suspects (kind of).
So why not install let users install the needed frameworks themselves?
Put the link below on Nant's help or as an output suggestion in case of such failures maybe?

(Anyway, no reply needed; I also happen to google upon this bug; so my post can also help other people in worst case.)
