Hi all,

Apologies if this is a basic question! I am looking to call the ODE library as a dll within LabVIEW as it is done here https://lavag.org/files/file/155-lvode/ and am mostly interested in the collision detection functions. The example in the link is for 32-bit dll but our application is 64 bit.

Could any of your source code that is on Bitbucket be used to generate a dll file on Windows?

Many Thanks,

Riley

Hi Riley,

Yes, probably some could. What tools do you have for the compiling?

Hi Oleh,

Thank you for responding so quickly! I haven't done this before but it looks like there is enough information on how to compile it in Visual Studio IDE with C++ that I can follow. Would that work?

Many Thanks,

Riley

Yes, for Visual Studio there is build\premake4.exe executable to generate a solution for you. You have to run a command prompt and generate solution files. Check command line options (premake4.exe --help) and choose what you need to be included. It can generate vs2010 files you can then convert to the version you need with your Visual Studio. Build and use the DLL it will generate. If you would want to use the DLL from your program there are include headers in include\ode.

Hi Oleh,

Thank you for the instructions, that was very helpful. I generated the vs2010 file, converted it to 2019 and then built the dll with no issues.

I am still having trouble importing it into my program though as the declarations for a lot of functions and typedefs in particular cannot be found. Some of them like dReal I can define manually but not sure how I can do that with structures like dSpaceID. I have included the ode.h from the include folder which should include common.h where they are called. I am also including the paths to the ode src folder, VS tools and Windows SDK headers. Do you recognise anything I might be missing?

Many Thanks, Riley

It looks like the compiler doesn't load ODE's header. Do you also have an error message telling it can't locate the header? Another way to see this is to show the includes when compiling, and making sure the right files are included: https://docs.microsoft.com/en-us/cpp/build/reference/showincludes-list-include-files?view=msvc-160

Hi Vaillancourt,

I'm attaching a screenshots of the paths I've defined and the messages (in the last one) .

If I add dReal = double in the preprocessor definitions then the create box declaration is found but as void * dCreateBox(void *space, double lx, double ly, double lz); and then the return is of an undefined type for my application.

Thank you for your help!

Also, thank you for the link, when building it looks like it didn't have any issues finding the header -

Hi Riley,

Add dIDEDOUBLE to your defines. If you are using libCCD also add CCD_IDEDOUBLE.
You should not define dReal manually.

You should not import the library. Including ODE headers is enough to have all the functions and types declared.
You only have to add the DLL into the shared library list for your linker.

Hi Oleh,

Thank you! I'm not sure what you mean with the dIDEDOUBLE added to defines. Do you mean define it manually as double as I was trying to do with dReal? Apologies, I don't have much experience with this.

I thought that only dll and header would be needed too but I get the error in the screenshot below about additional deader files missing, that is why I added the additional items to the list.

Many Thanks,

Riley

Do it for each [Configuration X Platform] combination you have.

Hi Oleh,

Thank you for the screenshot and arrows. They were already defined and still cannot find dReal.

Many Thanks,

Riley

How could they get into your project settings if you were not adding them there?
