Getting started - able to use a custom windows dll on linux?

[magick93]

Hello

My story is - I have a windows dll (a client for a web service) that I am currently using on Ubuntu with aid of Wine. This works fine-ish.

However I am interested in a more lightweight solution that can be used in containers.

I tried to get started but I'm not sure how I should use loadlibrary.

I tried: ./mpclient service_client.dll And got:

main(): Scanning  service_client.dll...
EngineScanCallback(): Scanning input
EngineScanCallback(): Scanning archive member !Themida

Can you let me know if loadlibrary is able to provide a wrapper, or a way to run my dll on Linux? Any guidance is appreciated.

Thanks

Hey, do you have header files for this dll? This project provides a framework for using Windows DLLs in native Linux code, it's not really possible to automate this process - it just provides the tools to dlopen() the DLL and call routines in it.

If you don't have header files, it would still be possible but would require good knowledge of windows internals.

Yes I do have the headerfile.

@taviso is it possible to use a DLL that calls functions from other DLLs? i.e.: HelloWorld.dll calls functions from PrintFunc.dll. both are windows DLLs.

Hi @taviso

Can you give an example of how to call methods in the dll? As mentioned, I do have the header file.

@magick93 did you manage to make that work? I'm on the same boat

[magick93]

No, unfortunately I didnt.
