DLL Maker Error

Hi,

Building DLL on the FlexSim DLL maker in visual studio 2017 brings down the following error attached(I didn't write any new functions, only default ones). It notifies to install v120_xp toolset or retargeting the solution. Even after doing this, the same message appears.

Any idea ? Or Is it better to use visual studio express 2013 or 2015? Or Am I missing something?

Regards,

Arun KR

@Arun KR I do see in the screenshot you are compiling for 32 bits. Is that correct?

It should be enough to change the project toolset to one that you do have installed. For Visual Studio 2017 this is the v141. You can set it in the project properties:

Be aware that this change is saved in the .vcxproj so if you check this in to version control the next user to open it in Visual Studio 2013 will have the same issue in reverse.

I am facing some issues while building DLL with visual studio 2019 version.

Here's the error message.

Anyone having the same issues ?

I don't have VS2019 installed to test it (we're still using VS2017), but you can change declaration.h in your solution.

Change how it defines fabs() and round() so that it compiles. Or just take out the declaration of fabs() and round() so that it doesn't try to connect to versions of those functions.

Those function declarations are there in order to maximize compatibility with FlexScript functions (by making all the FlexSim commands available). If you aren't using fabs() or round(), you don't need to define them.

You can change your declaration.h in the DLL Maker to suit your needs for the DLL you are trying to build.

I've compiled a few modules in VS2019 and did not see this issue. So there is more to it than just the upgrade from '17 to '19.
