Hi Pete,


> I'm having some trouble with EZCA. Does anyone else still use this?


Yes, we use it because it is part of the IDL EPICS interface.  It is also part of the matlab EPICS interface, which I don't use but I know that others do.


> Do we know if there are 64-bit issues with it?


I have been using it with 64-bit IDL for many years and have never seen any problems.


> Does it work with 3.15.5?


Yes.  Here is the output of ldd on my IDL shareable library for EPICS.

corvette:extensions/lib/linux-x86_64>ldd /usr/local/idl_user/epics/libezcaIDL.so_linux_x86_64
        linux-vdso.so.1 =>  (0x00007ffcaa342000)
        libezca.so => /usr/local/epics/extensions/lib/linux-x86_64/libezca.so (0x00007f077cbd5000)
        libEzcaScan.so => /usr/local/epics/extensions/lib/linux-x86_64/libEzcaScan.so (0x00007f077c9c9000)
        libca.so.3.15.5 => /usr/local/epics/base-3.15.5/lib/linux-x86_64/libca.so.3.15.5 (0x00007f077c75f000)
        libCom.so.3.15.5 => /usr/local/epics/base-3.15.5/lib/linux-x86_64/libCom.so.3.15.5 (0x00007f077c4ec000)
        libpthread.so.0 => /lib64/libpthread.so.0 (0x00007f077c2b9000)
        libreadline.so.6 => /lib64/libreadline.so.6 (0x00007f077c073000)
        librt.so.1 => /lib64/librt.so.1 (0x00007f077be6b000)
        libdl.so.2 => /lib64/libdl.so.2 (0x00007f077bc66000)
        libstdc++.so.6 => /lib64/libstdc++.so.6 (0x00007f077b95e000)
        libm.so.6 => /lib64/libm.so.6 (0x00007f077b65c000)
        libgcc_s.so.1 => /lib64/libgcc_s.so.1 (0x00007f077b445000)
        libc.so.6 => /lib64/libc.so.6 (0x00007f077b082000)
        /lib64/ld-linux-x86-64.so.2 (0x000055fd08911000)
        libtinfo.so.5 => /lib64/libtinfo.so.5 (0x00007f077ae57000)

So it is using the 3.15.5 versions of libCom and libca.


> I see wrong values from an ezcaGet of an array of long ints. The caget shell command gets the right values.


What version of ezca are you using?  The latest (though still over 4 years old) is on Github:

https://github.com/epics-extensions/ezca


You are referring to the function ezcaGet in the ezca library?  So you are calling this from an application you have written?


Can you send the source code for that application, and the incorrect output you are getting?


Cheers,

Mark

Hi Tech-talk,
I'm having some trouble with EZCA. Does anyone else still use this? Do we know if there are 64-bit issues with it? Does it work with 3.15.5? I see wrong values from an ezcaGet of an array of long ints. The caget shell command gets the right values.
Pete.
