I did not change the Andor linux-x86_64 libraries between 1.8 and 2.1.  They are all 2.84.

I did upgrade to 2.98 for the upcoming 2.2 release.

Commenting out the install in the andorSupport directory is fine.  Alternatively I think you can add a line to your Makefile that tells it where to find the libandor.so file, probably andor_DIR=/usr/local or something.

I cannot explain why it would not work for you with 2.1 since I did not update the library, and in any event you should not be installing the library that comes with ADAndor anyway.

What is the contents of ADAndor/lib/linux-x86_64?

Subject: Area Detector and Andor

Hi Mark,
I returned to our Andor problem and now I mostly understand what is 
going wrong.
It turns out that the libandor.so library which comes with the Area 
Detector package does not work with our version of the Andor SDK, which 
is version 2.94.  Building Area Detector package puts libandor.so in 
lib/linux-86_64, the IOC when built, links to the library in Area 
Detector, and when started, loads this library and the IOC almost works 
with the exception that no image data are received from the camera.
If I remove the libandor.so library from the Area Detector, build my IOC 
it links to the libandor.so library in the locally installed SDK 
package.  When I start the IOC it loads the SDK library and everything 
works; the image data are received from the camera.

Presently we have AD version 1.8, 1.9.1, and 2.1 installed.  I have 
modified a Makefile in the andorSupport directory not to install the 
andor libraries.  I am not sure if this is the correct way to deal with 
our problem.

One more problem remains.  This fix works with AD 1.8 and 1.9.1 but not 
with 2.1.
The IOC built with AD 2.1, still exhibits the same problem, all seems to 
work except for getting the image data.  I wonder if there is another 
level if mismatch between AD 2.1 and our SDK?
Thanks,
Zen
