Compile Real Time dll in MSVS 2008

[jonasz]

I'm trying to compile a dll which is supposed to run as the startup dll on a LabVIEW RT target. For starts, I took code that works fine in LabWindows/CVI (i.e. it compiles, and the resulting dll runs on the RT target). I created a new project in MSVS using the LabWindows/CVI Project template, as dll. I copied the code from the LabWindows project, and all compiles well. However, when I copy the resulting dll onto the RT target and set it as startup dll, I get an error message ('cvirte.dll not found').

I assume this is because I don't iclude the RT runtime dlls correctly; how would I achieve this?

Thanks,

jonasz,

Did you already see this: http://digital.ni.com/public.nsf/allkb/C6E2279078DEABDC86256896005D8F02 ?

cvirte.dll should be in the C:\Windows\System32 folder

As a matter of fact, I have. However, that is not my problem. My problem is that I'd like to compile a library for use on a LV/LW Real-Time target. If I link against cvirte.dll (and copy it on the target), I run into other dependency issues, as this uses functions not supported by the RT system.

I got (what I think is) a step further, making sure my code is not linked against default libs (/NODEFAULTLIB flag in MSVC++). However, I still get unresolved external symbols (__fltused, __ftol, __RTC_CheckEsp, __RTC_Shutdown, _RTC_InitBase, ___security_cookie, @__security_check_cookie@4, and @_RTC_CheckStackVars@8).

Is there a sample MSVC++ project for a 'Hello World' dll that compiles for and runs on a real-time target?

Try verifying the Visual C++ built dll with this checker: http://digital.ni.com/public.nsf/allkb/0BF52E6FAC0BF9C286256EDB00015230
