Support for 64-bit Windows in NI-CAN and/or NI-XNET APIs

[JaremyP]

Hello,

I was wondering if any new information for building 64-bit applications using NI-CAN and NI-XNET CAN devices was available. The driver package supports 64-bit Windows, but the programming library/DLL are still 32-bit only.

Thank you.

JaremyP,

That is still the case. This white paper points out that the NI-CAN and NI-XNET drivers are supported on 64-bit Windows, only while using using 32-bit Software.

Thanks,

I have the same question a year later. I would like to build a 64-bit windows executable that uses CAN. The white paper https://www.ni.com/en/support/documentation/compatibility/09/national-instruments-product-compatibil... seems to say that full 64-bit software support has been available for NI-XNET since version 14.0. However, I have NI-XNET 14.1 installed with the CAN compatibility layer, and I can only find a 32-bit version of nicanmsc.lib.

there is no 64bit support for NI-CAN available so far.

If you want to use CAN under 64bit applications you need to move entirely using NI-XNET hardware and driver software.

It looks like I'll have the same problem trying to use XNET directly. My NI-XNET installation contains only one version of nixnet.lib in C:\Program Files (x86)\National Instruments\Shared\ExternalCompilerSupport\C\lib32\msvc. How should I link my 64-bit executable?

I checked with NI-XNET 14.5 and there is a

Program Files (x86)\National Instruments\Shared\ExternalCompilerSupport\C\lib64\msvc\nixnet.lib

installed. Which XNET revision do you use?

I have NI-XNET 14.1 installed. I'll upgrade to 14.5 and see if I can find the 64-bit library. Thank you very much.
