Re: ADEiger for EIGER2

Hi John,


lz4 and bitshuffle are both provided in ADSupport/supportApp/bitshuffleSrc.  I would strongly recommend using those, and not your system versions.


I don't know why that code for lz4 and bitshuffle was added to eigerApp/src/Makefile.  It should not be needed. I would try deleting it.

I get a build error related to the lz4 library (see below) I poked around and I am confused about where lz4 gets configured. I am using base-7.0.3 , areaDetector-master (is that a problem?)

On out SL7 systems

>locate lz4
/usr/lib/liblz4.so.1
/usr/lib/liblz4.so.1.7.5
/usr/lib64/liblz4.so.1
/usr/lib64/liblz4.so.1.7.5

but I also thought bitshhuffle from ADSupport provides LZ4.

Finally, I see that

areaDetector/ADEiger/eigerApp/src/Makefile contains a section

ifdef LZ4_LIB
  lz4_DIR  += $(LZ4_LIB)
  LIB_LIBS += lz4
  bitshuffle_DIR += $(LZ4_LIB)
  LIB_LIBS       += bitshuffle
else
  LIB_SYS_LIBS  += lz4
  LIB_SYS_LIBS  += bitshuffle
endif

not in other ADEiger installs I have.

Hi, here's another approach:

$ git clone https://github.com/areaDetector/ADEiger

$ cd ADEiger/

$ git fetch origin pull/30/head:pr-branch

$ git checkout pr-branch

I think this way you get the result of merging to the target branch

Kind Regards,
Emilio

Hi John,


You can clone the repository issuing that pull request and then checkout that branch:


git clone https://github.com/dls-controls/ADEiger/

cd ADEiger

All,

I have a new EIGER 2 detector. I understand that this

https://github.com/areaDetector/ADEiger/pull/30

is the appropriate ADEiger for an EIGER 2.  True?

Can someone tell me how to clone this pull?

Thanks,

John Dobbins
