Compilation worked very well and was extremely fast, however, it is not
64-bit. When the compilation is complete what you get is a 32-bit
application running on a 64-bit OS. So basically, when we run EPICS it
the linux OS is in 32-bit compatibility mode.
To achieve the 64-bit mode we will have to throw the "-m64" flag to the
GCC compiler.
This is my next step but I sense there will be trouble as some of my
colleagues have forewarned me.
Thanks for clear this up.
However, the binary I got, for example, 'file medm' shows
medm: ELF 64-bit LSB executable, AMD x86-64, version 1 (SYSV), for
GNU/Linux 2.6.0, dynamically linked (uses shared libs), not stripped
How can it be a 32-bit application?
Just start to play x86_64 linux, sorry for the "rudimentary" question.
