Hi Zachary,

Unfortunately I recently realized that the pre-built version of the LightField driver won't work.

All of the other areaDetector pre-built applications are statically built.  The LightField driver cannot be statically built, because the Microsoft Common Language Runtime can only be used with dynamically built applications.  Because the LightField driver is dynamically built it depends on dozens of DLLs, including those from EPICS base, asyn, calc, autosave, etc.

LightField.dll is located in ADLightField/bin/windows-x64-dynamic, which is not distributed with the pre-built files (ADLightField/iocs/iocLightField/bin/windows-x64-dynamic is the directory with the LightFieldApp.exe application).  But even if LightField.dll were distributed you would then get more errors, because it would not find ca.dll, Com.dll, asyn.dll, etc.

I could write a script to include all of those DLLs, but I have not had a chance.

Meanwhile, you could build the LightField driver from the source code.

Mark

Subject: ADLightField Prebuilt - LightField.dll Not Found

Hi,

I've installed the pre-built binaries for Lightfield (upgrading from the Roper IOC I installed a while back for the WinView software) for the Princeton Quad RO detector, and on launch, LightFieldApp.exe crashes because it cannot find 'Lightfield.dll'.

The camera is functional in Lightfield.  The crash happens when running the start_epics.bat from either iocLightField or iocLightField2 included in the download.  The .dlls in the /bin/windows-x64-dynamic/ directory match the .dlls installed with the Lightfield software; I could not find a simply-named "Lightfield.dll" installed with the Lightfield software.

The dllPaths.bat has the appropriate path to the dll files that were included with ADLightField, and LightField also adds itself to Win7's PATH as well, so it should have proper direction to the Princeton.*.dlls if those are all the IOC should need.

Is there a specific Lightfield.dll, and where can it be found?

Thank you,

-ZB
