C# wrapper x86 #100

Closed jbres4 closed 3 years ago

jbres4 commented 3 years ago

Hi, I made C# development based on the C# wrapper included on the SDK. It's working fine. I was wondering if it would be possible to have a x86 version of the wrapper instead of the current x64 ? We have currently an existing project, which already uses different libraries all compiled in x86 (because one them come from third parties and only x86 versions are available). So to include our implementation of your C# wrapper in our project, we would need a x86 version. Thanks.

Hi, It is not officially supported, but you can try the following steps:

  1. Comment out the set(CMAKE_CSharp_FLAGS "/platform:x64") from the wrappers/csharp/CMakeLists.txt file
  2. cmake -G "Visual Studio 16 2019" -A Win32 -DRSID_PREVIEW=1

Hi, I've downloaded the latest release 0.23.0 today and tried what you suggested:

Then I tried to use these dll in my sample app (compiled in x86 in this case) which basically:

Preview, and enroll are working fine. But when I try to use Authenticator.Authenticate method, I see the red light of the camera and just after I get a System.AccessViolationException. StackTrace :

   at rsid.Authenticator.rsid_authenticate(IntPtr rsid_authenticator, AuthArgs& authArgs)
   at rsid.Authenticator.Authenticate(AuthArgs args)

Below is the CMake command output if it helps

The sample app is working fine when compiled in x64 and is using the released dll, or if if create the dll using CMake and default configuration.

Do you know what may cause this issue ?

Thanks.

Hard to tell. Like I said it is not supported. If you find a solution a PR would be welcome!

Hi @jbres4, I was wondering if you were able to use the SDK in x86, that would help us a lot!

jbres4 commented 2 years ago

Hi @luisruizlatic, no I was not able to have it work. And as the project is dead (the camera F455 is not available anymore since February 2022), I stopped looking at this...
