Use C++ dll in ARX

Rakusiri — Thu, 01 Jun 2023 03:49:45 GMT

I am stuck and need some help. I create a windows dll project with an exported method. Method does nothing but simply returns an int. Now when I create a ARX project and add this dll's path to the ARX's library directories, everything compiles great. However, when I load the ARX in AutoCAD, I get the following error

c:\users\rakusiri\source\repos\arxproject1\x64\release\adskarxproject1.arx cannot find a procedure that it needs. AcRxDynamicLinker failed to load 'c:\users\rakusiri\source\repos\arxproject1\x64\release\adskarxproject1.arx' c:\users\rakusiri\source\repos\arxproject1\x64\release\adskarxproject1.arxUnable to load ADSKArxProject1.arx file.

I have spend 2 days but can't get it to work. Can anyone please guide me. I am attaching the project and the ARX and DLL therein.

you can try adding the path to the DLL to "PATH" environment

Hope your dll-file was compiled and linked with the same options as main arx-file.

Thanks @daniel_cadext. That did the trick.

Thanks @Alexander.Rivilis I was making a static dll and that was causing the issue. Per your comment I matched the configuration to ARX project and then applied @daniel_cadext 's approach. That fixed everything. Thank you both.
