Hi Patrick,
Which architecture you build EPICS base and extensions for is controlled by the environment variable EPICS_HOST_ARCH. I suspect you built libezca with EPICS_HOST_ARCH=linux-x86. For 64-bits you need it to be linux-86_64.
You can tell which version the .so file is with the Linux "file" command:
corvette:extensions_devel/lib/linux-x86>file libezca.so
libezca.so: ELF 32-bit LSB shared object, Intel 80386, version 1 (SYSV), not stripped
You can also just look at what directory it is in. EPICS puts 32-bit .so libraries in lib/linux-x86, while 64-bit libraries are in lib/linux-x86_64.

Subject: ezca libray
Hi,
I'm trying to use the ezca library in a C program, but when I execute it
I get the error:
error while loading shared libraries: libezca.so: wrong elf class:
ELFCLASS32
I guess this means that libezca was compiled as a 32 bit library, while
the program is 64 bit? I thought I had compiled ezca as 64 bit. Is there
some flag I am missing, either when I compile the libezca extensions or
the program itself?
Thank you,
Patrick
