Can I link 64-bit C code to LabView ?

[gdargaud]

Hello, hello,

I'm asking here because I'm doing the C code...

I just created a DLL for use in LabView, based on some 64-bit libraries, but the LV dev refused it, saying he needs a 32-bit DLL.

I feel stuck: I cannot recompile the undelying libs. Is there a way out ?

64-bit code can only be linked and executed by a 64-bit process. The LabVIEW user needs to install the 64-bit version of LabVIEW!

Yeah, I should have checked the download page of LV first ! Anyway, I'm currently discussing why they still use an antiquated version of LV...

32bit is not "antiquated", just a different flavor of the same vintage.

There could be many reasons to use 32 bit,

• not all addons or toolkits are available in 64bit (see links here for details).
• a 64bit application cannot run on 32bit windows, 32bit application run fine on 32 and 64bit windows.
• The free community edition is currently limited to 32bit.
• etc.

Maybe your libraries are also available in 32 bit?
