RE: areadetector on windows, xml2 done, now Lightfield

[Freddie Akeroyd - STFC UKRI via Tech-talk <tech-talk at aps.anl.gov>]

Hi,

 

In other situations I have seen DLL load errors caused by a dependency of the DLL in question not being found i.e. ARC_Instrument_x64.dll may be present in the right place but one of the DLLs it depends on (and is located via the PATH environment variable) might be either not found or an old/incorrect version of this required file was installed by another program which happens to be earlier in PATH and so is picked up instead. Programs like dependency walker   https://www.dependencywalker.com/  can help locate such clashes if that is the problem

 

Regards,

 

Freddie

Hi William,

 

I am trying to understand why you get that missing DLL error.

 

Can run the camera OK using LightField as a stand-alone application without EPICS?

 

Do you have more than one version of LightField installed?

 

ADLightField does not call that DLL explicitly, it just starts LightField in this line:

 

https://github.com/areaDetector/ADLightField/blob/3383118260b82d95255f303d673e04d4de0123c9/lightFieldApp/src/LightField.cpp#L410

 

The missing DLL is ARC_Instrument_x64.dll.  I have attached a screen shot showing the size and location of that file on my system.  What do you see on your system?

 

Mark

Hi Mark,

Heres mine:

(no phoebus screenshot since my IOC doesn't start properly because of the error)

Environment: LIGHTFIELD_ROOT exists and is set correctly.

 

and PATH:

have Lightfield 6.14

 

AD is master branch everywhere.

I also noticed that the ddlPath.bat clobbers the PATH with each IOC boot until windows complains that the PATH is too long.
(this of course only happens if you launch the .bat from commandline, if launched via double-click its fine)

I'd suggest a change in dllPath.bat:

REM only extend PATH if not already done. save original path in _OLDPATH

IF "%_OLDPATH%"=="" SET "_OLDPATH=%PATH%"

REM first, restore original PATH

SET "PATH=%_OLDPATH%"

SET "PATH=S:\TUFF\EPICS;P:\UTS\HERE"

Hi William,

 

I just checked one of our systems which is running ADLightField.  I have attached 3 screens shots:

 

Lightfield.png  This is the medm screen for ADLightField.  It shows we are running 6.4.1 of the Princeton SDK, and 2.6.0 of ADLightField.

 

ENVIRONMENT.png  This shows all of the system environment variables.  Note the value of LIGHTFIELD_ROOT.

 

PATH.png  This shows all of the entries in the PATH environment variable.   Note the two entries for Princeton Instruments.

 

How do these compare to your system?

 

Mark

Hi William,

 

What version of LightField are you running?

 

What version of ADLightField are you running?

I would like to warm that up again.

I want to use areaDetector with / for Lightfield, and I run into the following problem:

System.TypeInitializationException: The type initializer for 'PIActon.ExperimentControl.DeviceManager' threw an exception. ---> System.TypeInitializationException: The type initializer for 'PIActon.SpectralDevices.DeviceManager' threw an exception. ---> System.DllNotFoundException: Unable to load DLL 'ARC_Instrument_x64.dll': The specified module could not be found.

any advice on that?

putting the mentioned .dll into the bin/windows-x64 folder alongside the IOC's .exe or into ADLightfield\bin\windows-x64 doesnt help unfortunately.

Thanks!

Hi Mark,

thanks for pointing it out. I guess, RTFM for me ;)
Nevertheless, I'd suggest moving that section of the manual to the top, so the interested one can directly see what is required to build areaDetector from source.
Also, I'd suggest a copyFromExample.bat. (with COPY /Y instead of cp)

FYI, I copied

C:\EPICS\epics-support\areaDetector\configure>copy EXAMPLE_RELEASE.local RELEASE.local
C:\EPICS\epics-support\areaDetector\configure>copy EXAMPLE_RELEASE_LIBS.local RELEASE_LIBS.local
C:\EPICS\epics-support\areaDetector\configure>copy EXAMPLE_RELEASE_PRODS.local RELEASE_PRODS.local
C:\EPICS\epics-support\areaDetector\configure>copy EXAMPLE_CONFIG_SITE.local.WIN32 CONFIG_SITE.local.WIN32

and I specified AREA_DETECTOR=$(SUPPORT)/areaDetector in my $(SUPPORT)/RELEASE.local file.

then areaDetector compiled from the TOP directory.

thanks for the help!

Note that it first build xml2.lib and xml2.dll and then built nanohttp.stream.lib and .dll.

 

The only reason it would not do this is if you have not defined XML2_EXTERNAL=NO.

 

1.       I haven't configured CONFIG_SITE.local at all - NO seems to be the default. (?)

 

Did you install CONFIG_SITE.local from EXAMPLE_CONFIG_SITE.local as explained in the InstallGuide?  https://areadetector.github.io/master/install_guide.html#release-and-config-files

 

I think the behavior you see can only be explained if you don’t have an areaDetector/configure/CONFIG_SITE.local file at all, or if you do have that file but have modified it from EXAMPLE_CONFIG_SITE.local. 

 

EXAMPLE_CONFIG_SITE.local does define XML2_EXTERNAL=NO in this line: https://github.com/areaDetector/areaDetector/blob/78fae55898b9028e756eb080367cd6aad8913b54/configure/EXAMPLE_CONFIG_SITE.local#L115

Hi Mark,

1.       Is XML2_EXTERNAL defined to be NO in areaDetector/configure/CONFIG_SITE.local?

I haven't configured CONFIG_SITE.local at all - NO seems to be the default. (?)

1.       Just before you get that error do you see xml2.lib being built?  Does it exist in the ADSupport/lib/windows-x64 directory?

no, and no.

thanks for helping :)
