Not able to run SWIG C# examples in VS 2010
I am trying to get SWIG to work with Visual Studio and C#.
I downloaded swigwin-2.0.4.zip and converted the project to a VS 2010 project.
I am able to build the 'class' example. When I then try to run compiled build I get开发者_如何学Python the error
The type initializer for 'examplePINVOKE' threw an exception.
I haved googled the error, but have not found any suggestions on how to resolve it.
Hope somebody is able to help!
Thanks,
Christian
What worked for me was to:
- Go to Build->Configuration Manager. For the C# project change
AnyCpu
tox86
and rebuild. - Copy example.dll to bin\x86\Debug (Release).
Doesn't require CorFlags.
I got the following answer from Gregory Bronner on the swig-user mailinglist:
I had this issue as well (VS2010 , Windows 7, 64 bit computer, 32 bit mode dll, .NET 4) :
The problem actually relates to being unable to load the DLLs
There were two causes:
#1: All DLLs used by the C# assembly need to be in the same directory (or you need to change the lookup paths).
#2: The C# or the C++ DLL (I forget which) had incorrect CofFlags -- use CorFlags /32Bit+ *.dll or something like that. You could also try using /UpgradeCLRHeader
#3: You need to target the .NET 4.0 system in the project file, but 1 and 2 should get you started.
I will try these hints out and see whether they work and then post an answer if I am able to resolve the issue.
The solution for me was
- Move the used dll's to the Release (or Debug) directory
- Run CorFlags /32Bit+ file.exe
where file.exe is the executable produced by building the code.
