Hi,

This is probably a total newbie question, sorry for that - but I can't seem to see the answer...

We are looking to use NHibernate with our project, but we are already using log4net 1.2.10.0 (the one with the strong name change... http://marc.theaimsgroup.com/?l=log4net-user&m=115089697317244&w=2

I tried to run NHibernate with this version, but got this error:

Code:
Could not load file or assembly 'log4net, Version=1.2.9.0, Culture=neutral, PublicKeyToken=b32731d11ce58905'


So I thought, no problem I'll recompile NHibernate against the new version... I built NH using the 1.0.2 install no problem - so I switched the log4net.dll and got then this error during the build:

Code:
            build:

               [attrib] Setting file attributes for 1 files to Normal.
                  [csc] Compiling 478 files to 'C:\installed\nhibernate-1.0.2.0\build\nhibernate-1.0.2.0\bin\NHibernate.dll'."
                  [csc] fatal error CS0009: Metadata file 'c:\installed\nhibernate-1.0.2.0\build\nhibernate-1.0.2.0\bin\log4net.dll' could not be open
ed -- 'Version 2.0 is not a compatible version.'

            BUILD FAILED

            C:\installed\nhibernate-1.0.2.0\src\NHibernate\NHibernate.build(70,4):
            External Program Failed: c:\WINDOWS\Microsoft.NET\Framework\v1.1.4322\csc.exe (return code was 1)

            Total time: 1.4 seconds.


Any thoughts?

Thanks in advance,
Chris

You're building NHibernate against the 1.1 framework. So, quick sanity check, did you grab the log4net dll out of the 1.1 directory of the distribution? (log4net-1.2.10/bin/net/1.1/release/log4net.dll)

Thanks - that must be it - its the other way around - I am using .Net 2.0 - but using the 1.1 hibernate....

Told you it was a total newbie question!

Thanks.

How are you building this? MS Build or Nant?

I assumed you were trying to build with the 1.1 framework because of this line:

Code:
External Program Failed: c:\WINDOWS\Microsoft.NET\Framework\v1.1.4322\csc.exe

I am away from my desk now and so can't answer fully - but I am using nant and missed the bit you pointed out about the error coming from the 1.1 csc.exe.

Perhaps there is a flag in the nhibernate nant script I need to switch for 2.0 or something in nant to make it the default.

Thanks,
Chris

Do one of the following. Either add this at the top of the build file:

Code:
   <property name="nant.settings.currentframework" value="net-2.0" />



Or, invoke Nant like this:
Code:
>nant -t:net-2.0


Or, update your nant.exe.config from this:

Code:
    <nant>
        <frameworks>
            <platform name="win32" default="auto">


to

Code:
    <nant>
        <frameworks>
            <platform name="win32" default="net-2.0">

Hi,

It seems the nh 1.0.2 is not setup for .net 2.0 - I am going to try the 1.2 route instead - our DB is small and so the risk should be low.

Thanks for all the ideas
Chris
