[Mono-aspnet-list] Linq libraries missing?

Tue Apr 7 09:07:06 EDT 2009

-pkg:dotnet35 - Great thats two new commands you've taught me. Many thanks!

Unfortunately while working perfectly well on my local machine on my server
it reports that it cannot find this package.

Output:
Package dotnet35 was not found in the pkg-config search path.
Perhaps you should add the directory containing `dotnet35.pc'
to the PKG_CONFIG_PATH environment variable
No package 'dotnet35' found

Luckily I'm completely aware of the difference between an assembly and a
namespace. Sorry if you misunderstood me to imply that an assembly of
'System.Linq.dll' existed when I really meant that my file was using the
'System.Linq' namespace. Anyway I think we both understand this so its
really a moot point.

I've checked my Visual Studio and yes you are right it has a reference to
System.Xml.Linq.
Its path I find most odd: c:\Program Files\Reference
Assemblies\Microsoft\Framework\v3.5\System.Xml.Linq.dll

Shouldn't it be in my Gac and not Program Files? Bear in mind this is added
completely automatically by Visual Studio in all its wisdom and an no point
did I tweak this reference myself.

I've gone and copied System.Xml.Linq.dll to the bin folder of my website on
my server and with the inclusion of the -r:System.Xml.Linq it no longer
complains about Linq!!! :)

So thank you very much for your help. I guess that somehow the 3.5 version
of the framework files was included in the Mono2.2 installation on my Mac
OSX local machine somehow because I didn't explicitly install it myself.

Only one other problem remains which is the big compile error I've written
about in another thread which is rather more serious and sadly no one has
responded to it.
It can be found here: http://go-mono.com/forums/#nabble-f36223

Many thanks
Mark
