Linker issues with "cargo build" in Windows?

[mattia-donato]

Hello,

I am trying to compile with the command cargo build your version of "ni-fpga-rs" and I get a linker error.

  = note: LINK : fatal error LNK1181: cannot open input file 'NiFpga.lib'
error: could not compile `integration` (bin "integration") due to previous error

Where I can get it? I can find only NiFpga.DLL in LabView folder.

Hello,
This project has primarily been developed to target Linux where a static version of NiFpga is available. Your best bet is probably trying to find a static version for Windows. If that's not possible, loading a DLL at runtime would require some changes -- mainly replacing FFI calls in session.rs with dynamic equivalants -- but nothing too different. Unfortunately I don't have a Windows machine with LabVIEW to test against, but a PR to conditionally use the dynamic approach on Windows would be welcome.

Thank you for your answer.
In the meanwhile, I could compile. I still have to test but googleing i found out that it is possible to convert a ".dll" to a ".lib" by the following by running on the cmd.exe inside Visual Studio environment the following:

echo LIBRARY NIFPGA > nifpga.def
echo EXPORTS >> nifpga.def
for /f "skip=19 tokens=4" %A in ('dumpbin /exports nifpga.dll') do echo %A >> nifpga.def

and then

lib /def:nifpga.def /out:nifpga.lib /machine:x64

This is fixed with #33. It now dynamically links to nifpga, which is installed on system32 on windows. @auscompgeek this should be closable now.

I'll bump the versions later today.
